Use these RDX Fuel injectors in your Honda Engine as an upgrade over the standard injectors. Great for boosted applications with higher fuel demands than stock injectors can provide.

These injectors are rated for 410cc (at 38 psi) and 550cc (at 70psi) and offer a much improved spray pattern over the factory non-turbo spec injectors. These features offer the K- and J-series engine increased fuel flow and better fuel atomization. They are the perfect upgrade for stock and modified engines, even under boost. Stock bottom end motors with cams, valvetrain and upgraded intake manifolds may already be maxing out the duty cycle of the factory injectors. Please note that Kpro, Flashpro, Ktuner, or other engine management is essential to control these higher flowing injectors.

These injectors are sold individually. Please order the qty needed for your engine. These injectors will require harness adapters for non-RDX applications because the RDX uses a different style of connector.

Customer Questions


I have a 2007 TL base model, do these injectors need to be modified at all to fit?




would using a fuel pressure regulator be sufficient enough to use these without having to use engine management?


The answer here is completely dependent on your setup and fuel needs. We would not recommend changing out fuel injectors without planning on tuning for them.


I'm not clear on one of the topic, but isn't OEM a genuine factory part? So is this part made from Honda/Acura factory OEM?


Yes OEM and Geniune are used interchangeably a lot of times. This is a GENUINE part, meaning it comes straight from Acura. Read more on this topic here: What is the difference between OE, Genuine, OEM, and OER/Aftermarket Parts?

Q: Should I go with an upgraded fuel rail when I change from the 310cc to the 410cc injectors?

No that is not necessary.

Q:Does this fit a 2008 Honda Accord J35z3? Also does this fit on stock J35z3 Fuel rails?

Yes these injectors will fit your engine, and will need the Toyota/Scion injector clips.
