Engine swap projects (K-swap, B-swap, H-swap, F-swap) on Honda EF \/ EG \/ EK Civic and DC2 Integra chassis universally require routing the engine harness through the firewall, and the factory rubber grommets are typically too soft, prone to wear, and create the cluttered \"racecar wiring through cracked rubber\" appearance that ruins otherwise clean engine bay builds. This billet aluminum grommet replaces the factory plastic\/rubber pass-through with a clean machined aluminum hole that protects the harness from rubbing while delivering motorsport-grade aesthetics. The 0.65\" smooth interior hole accepts standard engine harness diameters with proper clearance, while the anodized finish maintains its appearance over years of engine bay heat exposure.\u003c\/p\u003e\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003ePremium 6061-T6 aluminum construction – CNC machined from aircraft-grade aluminum for exceptional lightness, strength, and durability\u003c\/li\u003e\n\u003cli\u003eSmooth 0.65\" interior hole – allows clean harness pass-through while preventing wire rubbing that damages insulation over time\u003c\/li\u003e\n\u003cli\u003eAnti-rust anodized finish – delivers superior corrosion resistance for sustained underhood and weather exposure\u003c\/li\u003e\n\u003cli\u003eDirect firewall installation – fits factory firewall holes between 1.05\" and 1.25\" diameter\u003c\/li\u003e\n\u003cli\u003eBlack anodized color – clean motorsport-grade aesthetic that complements any engine bay color theme\u003c\/li\u003e\n\u003cli\u003eIncludes mounting hardware – complete kit ready for installation without additional sourcing\u003c\/li\u003e\n\u003cli\u003eWide compatibility – fits the most popular Honda chassis platforms for engine swaps and harness routing projects\u003c\/li\u003e\n\u003cli\u003ePermanent solution – will not crack, deteriorate, or fail like factory rubber alternatives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eSpecifications:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eCondition: 100% Brand New\u003c\/li\u003e\n\u003cli\u003eType: Firewall Wiring Harness Grommet\u003c\/li\u003e\n\u003cli\u003eMaterial: 6061-T6 Aircraft-Grade Billet Aluminum\u003c\/li\u003e\n\u003cli\u003eConstruction: CNC Machined\u003c\/li\u003e\n\u003cli\u003eSurface Finish: Anodized\u003c\/li\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003cli\u003eInner Hole Diameter: 0.65\" (16.5mm)\u003c\/li\u003e\n\u003cli\u003eFits Factory Firewall Holes: 1.05\" – 1.25\" (26.7mm – 31.75mm)\u003c\/li\u003e\n\u003cli\u003eItem Weight: 0.1 kg\u003c\/li\u003e\n\u003cli\u003eQuantity: 1 grommet per pack\u003c\/li\u003e\n\u003cli\u003ePosition: Firewall Pass-Through\u003c\/li\u003e\n\u003cli\u003ePurpose: Engine Harness Routing \/ Engine Swap Component\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eFitment:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eHonda Civic EF (1988 – 1991)\u003c\/li\u003e\n\u003cli\u003eHonda Civic EG (1992 – 1995)\u003c\/li\u003e\n\u003cli\u003eHonda Civic EK (1996 – 2000)\u003c\/li\u003e\n\u003cli\u003eAcura Integra DC2 (1994 – 2001) – Including Type R\u003c\/li\u003e\n\u003cli\u003eCompatible with factory firewall holes between 1.05\" and 1.25\" diameter\u003c\/li\u003e\n\u003cli\u003eSuitable for engine swap projects (K-swap, B-swap, H-swap, F-swap, etc.) requiring clean harness firewall routing\u003c\/li\u003e\n\u003cli\u003eConfirm vehicle model and firewall hole size before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eContents:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e1x Billet Aluminum Firewall Grommet\u003c\/li\u003e\n\u003cli\u003eAll necessary mounting hardware included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eImportant Compatibility Notes:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirewall hole size:\u003c\/strong\u003e This grommet is designed to cover factory firewall holes between 1.05\" and 1.25\" diameter.
