MRC Racing Components K20 K24 K-Series Tucked Engine Harness For Honda Acura

Clean up your K-swap engine bay with a purpose-built wiring solution. The MRC Racing Components K-Series Tucked Engine Harness is a premium replacement harness designed for 2002-2004 RSX Type-S applications and engineered to work seamlessly with most K-series swap builds. Every wire is shortened, re-routed, and tucked for a clean, professional-looking engine bay while maintaining full OBD2 compliance and reliable operation.

This is not a hack job or a budget splice harness. Every connection is purpose-built for the K-series engine, with proper wire routing that keeps things clean and organized. Designed for both performance and appearance, it is the harness your swap deserves.

Pro Tip: A clean engine bay starts with clean wiring. The tucked harness eliminates the biggest visual eyesore in most K-swap builds. If you are going through the effort of a swap, do it right from the start — retrofitting a tucked harness after the engine is already in is significantly more work than installing one during the build.
