An affordable alternative fuel injector set that is highly regarded by the K-series enthusiast community! RDX injectors provide 410cc's and a unique spray pattern over regular factory K20A and K24A injectors.
Dyno tests have shown (via forums) a bolt-on performance gain of approx. 5hp by just switching over to RDX injectors. Some tuning may be required depending on engine application.
These also work for B/D/F/H-series engines with an aftermarket fuel rail (specifically made for RDX injector) along with an engine management system.
Sold as a set of 4 injectors.
