The Precision Raceworks N55/S55 Upgraded DI Injectors are designed for customers looking to push the limits without port injection (or in addition to port injection).  Our high flow injectors were developed in a partnership with NHP, taking advantage of resources offered by both companies to produce the highest quality and highest flowing direct injector upgrade ever for the N55 engine.

These high flow injectors flow 55% over stock!  This means that these can support up to *950 whp on gasoline or *715 whp on E85 without PI!

Each injector is tested and calibrated using state of the art high pressure flow calibration equipment and then matched to a set of 6.  

Installation of these is a snap and is as simple as replacing your injectors, a little coding, and then checking a checkbox!  You can make installation even easier with our Direct Injector tool!

Can I run E85?  Of course!  Just like all other Precision Raceworks products our direct injectors are compatible with E85 and all other fuels as well!

Is it supported by tuners?  Absolutely!  The Precision Raceworks stage 2 direct injectors are supported by MHD, Bootmod3, Ecutek, and others.  If you need help beyond that just give us a shout and we will get you fixed up!

*Only works with cars with factory electronic wastegate

whp is a theoretical based on overall capability of injectors and with a fully built system and all supporting mods.
