410cc Fuel Injectors

The Acura RDX 410cc Injectors are a direct upgrade for K-Series engines, offering a significant increase in fuel flow and improved spray pattern for enhanced engine performance. These genuine RDX OEM injectors are designed to provide the necessary fuel headroom for modified naturally aspirated K20 and K24 engines, particularly those with bolt-on modifications such as cams, intake, headers, or exhaust systems. Compared to stock Honda injectors, these 410cc units offer more consistent fueling at both low pulse widths and wide-open throttle (WOT). This leads to better atomization, resulting in stronger midrange power and sharper throttle response. The kit includes four genuine Acura RDX 410cc fuel injectors and four RDX injector clips with pins, ensuring a plug-and-play installation on most K-Series harnesses without the need for wiring modifications or adapters. These injectors are compatible with a wide range of Honda and Acura models featuring K-Series engines, including the 2007–2010 Acura CSX Type S, 2007–2012 Acura RDX, 2002–2006 Acura RSX, 2004–2008 Acura TSX, 2003–2007 Honda Accord (K24), 2002–2005 Honda Civic Si, 2006–2011 Honda Civic Si, 2002–2006 Honda CR-V, and 2003–2011 Honda Element. They are also suitable for any K-swap build utilizing these engines.
