Acura RDX 410cc Injector Upgrade – OEM 410cc Fuel Injectors for K-Series Power Builds
If you're pushing your K-Series harder than stock, these Acura RDX 410cc fuel injectors are the go-to Honda injectors upgrade. They’re genuine RDX OEM injectors that drop into most K20/K24 setups and K-swaps and give you the fuel headroom you need without turning your car into a nightmare to tune or drive.
Compared to standard Honda injectors, these Acura 410cc fuel injectors flow more, have a cleaner spray pattern, and give more consistent fueling at both low pulse width and WOT. That means better atomization, stronger midrange, and sharper throttle response. These Acura K-Series high flow injectors work really well on cars with cams, intake, header, exhaust, or full bolt-on packages, while still keeping idle nice and stable. Each kit includes four RDX OEM injectors plus RDX injector clips included for plug-and-play on typical k series harnesses, so you’re not chasing wiring or adapters.
