JDC Titanium Valve Cover Hardware Kit | Mitsubishi Evo X

Replace rusty, corroded, or worn factory valve cover hardware on your Mitsubishi Evo X with the JDC Titanium Valve Cover Hardware Replacement Kit. Each fastener is precision CNC-machined from 6AL-4V Grade 5 titanium, giving your 4B11T engine bay a premium upgrade with exceptional corrosion resistance and the vibrant anodized finishes JDC Titanium is known for.

The valve cover bolts are engineered to match the critical depth and diameter specifications of the OEM hardware while incorporating JDC's custom-designed low-profile head for a cleaner, more flush appearance. The kit is compatible with both plastic and aluminum Evo X valve covers, with two kit configurations available depending on how much factory hardware you want to replace.

Whether you are restoring an aging engine bay or completing a full JDC Titanium dress-up package, this kit replaces ordinary factory hardware with purpose-built titanium fasteners designed specifically for the Evo X platform.

Key Features

  • Designed for Mitsubishi Evo X 4B11T applications
  • CNC machined from 6AL-4V Grade 5 titanium
  • Designed to match OEM valve cover bolt depth and diameter
  • Custom JDC low-profile head design for a cleaner appearance
  • Compatible with plastic and aluminum valve covers
  • Excellent resistance to rust and corrosion
  • Available in multiple JDC anodized titanium colors
  • Two kit configurations available

Torque Specifications & JDC Testing

The factory-recommended final torque specification for the Evo X valve cover hardware is 48.5 +/- 4.5 inch-pounds. Always use a properly calibrated inch-pound torque wrench and a 5mm Allen key when tightening the JDC valve cover bolts. Do not use a Torx bit.

JDC has physically torque-tested the Evo X titanium valve cover bolts to establish a substantial safety margin beyond the factory specification. During testing, the bolt head did not strip until approximately 14.5 ft-lbs, or 174 inch-pounds. This is more than three times the factory final torque specification. If you strip a bolt, you're doing something wrong.

Before Installation

Clean gloves are recommended when handling anodized titanium to prevent skin oils from transferring onto the finish. If gloves are unavailable, thoroughly wash and dry your hands before handling the hardware.

After installation, fingerprints or oils can be removed using mild soapy water, Windex, or our proprietary JDC Titanium Cleaner, and a clean microfiber towel. Avoid abrasive cleaners, water spot remover, or acidic cleaners that could damage the titanium finish.

Installation Instructions

Step 1: Remove all factory valve cover bolts except the bolts located in positions 1 and 2 on the factory torque diagram. Leaving these two bolts installed temporarily helps keep the valve cover properly centered. Install the remaining JDC titanium bolts and loosely tighten them by hand.

Step 2: Following the factory torque sequence, torque the valve cover bolts to 26.5 +/- 8.8 inch-pounds in the specified order. When you reach bolt 18, remove factory bolts 1 and 2 and replace them with the JDC titanium bolts. Continue the sequence beginning with bolt 3 and perform the final torque to 48.5 +/- 4.5 inch-pounds. Be sure to complete the final torque procedure on bolts 1 and 2 as well.

If you purchased the Basic Kit, installation is complete. If you purchased the Full Kit, continue with the following steps.

Step 3: Locate the four M6x20mm titanium bolts included for the ignition coil packs. Remove the original coil pack bolts and replace them with the new titanium hardware. Hand tightening is sufficient for these fasteners.

Step 4: Remove the three factory bolts securing the wire clips on top of the valve cover. Pinch and remove the black clip from the bracket to access the factory bolt with a 10mm socket. Replace the original hardware with the M6x12mm titanium bolts. Hand tightening is sufficient.

Step 5: Remove the two factory bolts located on top of the fuel rail and replace them with the supplied M6x12mm titanium bolts. Hand tightening is sufficient for these fasteners.

Step 6: Inspect your installation, clean any fingerprints from the titanium, and enjoy the finished engine bay. Take a few photos and tag @JD_Customs_USA for a chance to have your Evo X featured on our Instagram story.

Important Installation Notes

  • Factory final valve cover torque is 48.5 +/- 4.5 inch-pounds
  • Initial torque sequence is 26.5 +/- 8.8 inch-pounds
  • Use a 5mm Allen key for the JDC valve cover bolts
  • Do not use a Torx bit
  • Use an inch-pound torque wrench for accurate installation
  • Follow the factory tightening sequence to maintain even clamping pressure

JDC Titanium Colors & Care

Choose from a wide range of anodized finishes to coordinate your valve cover hardware with the rest of your engine bay. View our JDC Titanium Color Options for available colors and specialty finishes.

For cleaning recommendations and information on preserving your anodized finish, visit our JDC Titanium Maintenance and Care guide.

Why Choose JDC Titanium?

JDC Titanium hardware is designed for enthusiasts who care about the smallest details of their build. Rather than using generic titanium bolts, this kit was developed specifically around the Evo X valve cover with OEM dimensions, a custom JDC head profile, and hardware selected for the surrounding engine components.

From precision CNC machining and hand finishing to anodizing, assembly, and torque testing, JDC puts careful attention into every step of the process. The result is a purpose-built titanium hardware kit that combines fitment, durability, corrosion resistance, and the bespoke engine bay appearance JDC Titanium has become known for.

Took 2 weeks to deliver with standard shipping. But well worth the wait. Install took 25 minutes with minimal tools and the lights look amazing. Fitment is perfect and the quality is excellent. Its kinda pricey but you get what you pay for with ntxglow products. Highly recommend!

Customer photo review of Spec-D Projector Headlights Ford F150 (04-08) Mark LT (06-08) Halo Black / Smoked / Chrome

They look amazing, and after using ChatGPT to help me understand how to install them (because the instructions were not very helpful whatsoever), I’m glad with how they turned out. My problems are that the lights aren’t too bright, the instructions weren’t helpful, and the arrival date was wrong, even if they arrived early.

Customer photo review of 1993-1997 Honda Del Sol Redclear Tail Light Lenses

This isn’t on K2, but the lenses came In which I was thrilled about. I’d already removed my OEM lenses from their housings. The passenger side lense fit well and mostly flush. The driver side, however, looks like it was slightly warped and caused poor fitment and what looks like a small dip in the red portion of the lense. I had no choice but to use them, as my OEM lenses were no longer usable. It can be very difficult to get replacement lenses in a timely manner for a Del Sol. I drive my car everyday, so I had to just go with it. Again, not a K2 issue but presumably the manufacturer.

Customer video review of 2003-2008 Nissan 350Z N4 Style Rear Bumper Cover - FRP

This rear bumper fits great the only thing is the trunk button on the bottom is cut a little to wide but that’s an easy fix it looks great and definitely makes the rear look more aggressive. I love it!

Customer photo review of Upgraded VANOS Oil Supply Line – M52 / M54 Engines (E36, E46, E39, E60, X3, X5, Z3, Z4)

The box was a little crushed, but the line was packed well and it wasn't a problem. The instructions are 3 pages of color pictures and lots of explanations. Very nice. The line itself is a very nice bit of kit with a swivel AN line end that allows a No-tension install. No leaks so far and it looks great. It came with new banjo bolts and copper crush washers. The only criticism I have is that I would have liked this hose coated in black so it disappears like the original, but it does look good, so I don't mind.

Frequently Asked Questions

How do I know this will actually fit my car?

Every part listing shows compatible years, models, and trims. But here's the thing—trim packages and factory options can be confusing. If you're not 100% certain, text us at 772-277-2495 with your VIN or photos of your car. We'll verify fitment before you order so you're not stuck with an $800 part that doesn't fit. We've done this for 30,000+ builds. We've seen every weird trim combo and factory option. Takes us 2 minutes to verify, saves you weeks of headaches.

What if the part arrives damaged or is the wrong item?

We handle it. You don't fight with freight companies or file claims. Text us photos within 48 hours of delivery. If it's damaged or wrong, we ship a replacement immediately. You're not waiting 6 weeks for a freight claim to process. We eat the cost, not you. This is why we package everything like it's going to war. But if something slips through, we fix it ASAP. No forms, no back-and-forth, no "file a claim and wait." Just text us and we handle it.

Can I install this myself or do I need a shop?

Depends on the part. Emblems, front lips, some spoilers, bolt-on, DIY-friendly, you can do it in your driveway with basic tools. Full bumpers, hoods, wide-body kits, possible for experienced DIYers but most people take them to a shop for paint and install. Check the product description for installation difficulty. If you're unsure, text us. We'll be honest about whether you can handle it or if you should take it to a pro. We'd rather you know upfront than get frustrated halfway through.

What's your return policy if it doesn't fit or I don't like it?

Return policy

See the return policy for this item’s details. Questions? We’re happy to help before you order.

Read return policy · Contact us

Do you offer financing?

Yes. Affirm and Shop Pay available at checkout for orders over $50. Split payments over 3-12 months depending on order size. No hard credit check to see your options. Most people use this for big-ticket items like body kits, suspension setups, or wheel/tire packages. Rates vary based on credit. You see the monthly payment before you commit. Makes it easier to build now instead of waiting months to save up.

What if I have questions after I receive the part?

Text 772-277-2495. We don't disappear after you buy. Fitment questions, installation issues, "does this bolt go here" questions... we'll walk you through it. We've installed these parts ourselves or helped hundreds of people install them. You're not getting transferred to a call center in the Philippines. You're texting someone who's actually installed your part before. If we can't help remotely, we'll recommend a local shop that knows these parts.

Why should I buy from K2 instead of eBay/Amazon/other sites?

eBay and Amazon sellers don't answer fitment questions. They don't verify your VIN before shipping. They don't handle freight damage claims for you. If something goes wrong, you're filing disputes and waiting weeks. We're builders selling to builders. We verify fitment before you order. We handle damage claims same-day. We answer texts in minutes. We're not the cheapest, but you're not gambling $800 on whether a part fits. You're paying for support, verification, and someone who cares if your build goes sideways.

Shipping

Do you ship overseas?

Yes, we ship all over the world. Shipping costs will apply, and will be added at checkout. We run discounts and promotions all year, so stay tuned for exclusive deals.

How much does shipping cost and when will I see the total?

Depending on where you're located, small parts can ship free. Large parts like bumpers, hoods, and body kits require freight shipping. Uou'll see the exact cost at checkout before you pay. Freight usually runs $150-$300 depending on size and your location. We know it's expensive. We negotiate the best rates we can. If you're ordering multiple large parts, text us. We can sometimes combine shipping and save you money. We're not hiding fees in the final step. What you see at checkout is what you pay.

How long will it take to receive my order?

It depends on where you are. Orders processed here will take 5-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.
