S58 / B58 Gen 2 High Flow Direct Injectors by Precision Raceworks

The Precision Raceworks B58/S58 Direct 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 B58/S58 engine.

These high flow injectors flow 26% over stock (S58) and 60% on the B58! This means that these can support up to *930 whp on gasoline or *840 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.  

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 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!

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