K-Tuned RDX Injector Hats were designed to allow B and D series owners to install oem RDX Injectors on their older engine applications. This injector setup is a very cost effective alternative to expensive aftermarket injectors and is much simpler and better than the popular DSM injector modifications.

RDX Injectors are rated for 410cc (at 38 psi) and 550cc (at 70psi) and offer a much improved spray pattern over factory and most aftermarket injectors. These features offer your B or D series engine increased fuel flow and better fuel atomization.

They are the perfect upgrade for stock and modified engines. Stock bottom end motors with cams, valvetrain and upgraded intake manifolds may already be maxing out the duty cycle of the factory injectors, and turbo builds most certainly will. Sold as a set of four.

Note: (1) Injector clips change required (2) Engine management system required (Hondata S300 or AEM EMS) to modify injector rate settings (410cc).


We realize that returns and exchanges are a part of the purchasing process and we do our best to make it as easy as possible. If you are not 100% satisfied with your purchase, you can return your order to JHPUSA within 14 DAYS from the invoice date.
