FAQs

Will this fit the factory trunk?

It's made for the vehicle fitment listed on this page. Confirm your model and trunk style before ordering, especially if your car has an aftermarket trunk or existing spoiler holes.

Will I need to drill into my trunk?

Some spoilers use 3M tape mounting (no drilling), others require bolt-through installation. The spec sheet tells you which. Once holes are drilled, they can't be undone.

Does it ship painted or unpainted?

Most ship unpainted and require paint to match your vehicle. A small number are available pre-painted in factory colors — the spec sheet tells you which.

Will a rear wing affect my backup camera or sensors?

Most wings sit above the trunk and don't interfere with backup cameras or parking sensors. Tall wings on hatchbacks may affect rear visibility — check the install photos to see how it sits relative to your rear glass.

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

Please review the product details and return policy for this item’s eligibility, conditions and exceptions. Contact us before ordering if any terms are unclear.

Read return policy · Contact us

This information does not change your existing purchase terms or statutory rights.

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.

What does your warranty cover?

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.

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.
