Honda R18A1 Piston Kit — 81.00mm Standard Bore | OEM-Quality Rebuild
Bring your engine back to factory spec — without the factory price.
Built for standard engine rebuilds, this piston kit is manufactured to OEM specifications for the Honda R18A1 engine. Made from high-silicon aluminum alloy, it delivers the durability and fit of the original equipment, making it the reliable choice for daily-driven Civics that need a straightforward refresh rather than a performance upgrade.
Whether you're addressing worn cylinders, restoring compression, or doing a full engine rebuild, this kit is matched precisely to OEM tolerances for a trouble-free fit.
Why Choose This Kit
- OEM-Spec Fit — Matches Honda's original 13010-RNA-A01 reference for guaranteed compatibility
- High-Silicon Aluminum Alloy — Reliable strength and wear resistance for standard driving conditions
- Standard 81.00mm Bore — No boring or honing required for stock-spec blocks
- Rebuild-Ready — Ideal for routine maintenance, high-mileage refreshes, or worn-piston replacement
Fitment
- Honda Civic 1.8L (2006–2012)
Confirm your engine code (R18A1) before ordering — check your VIN or engine bay sticker if unsure.
