 These are GENUINE DENSO Honda/Acura 550cc (K-series) saturated injectors. Theses comes with injectors Pigtails AND K Tuned Injector Hats to fit on Popular B/D/F/H Series Engines (Some Modifications have to be done with certain fuel rails). 

These are an affordable alternative fuel injector set that is highly regarded by the K-series enthusiast community! These are the same dimensions as the RDX injectors which provide 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 STYLE injectors. Some tuning may be required depending on engine application. The main reason is the better spray pattern/ atomization .. the finer the mist, bette the burn of the air fuel ratio. 0
