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.

Holds up to chewing, but squeaker didn't last.
Pattern Name: Pumpkin, Size: Large
This pumpkin dog toy for aggressive chewers has held up to the chewing, but the squeaker, which they boasted as indestructible didn't hold up. It lasted maybe 12 hours and now it no longer squeaks which takes away a lot of the fun for my dog.

Bully breed has not destroyed the toy yet
Pattern Name: Apple, Size: Large
Ordered this toy for my Doberman and beagle who destroy every toy they are ever given. The green rope on top of the apple toy lasted for about 24 hours, and the squeaker inside the toy lasted for about 3 days. But the overall body of the toy is still in tact and it has been over a month now. The dogs still play with it despite the squeaker not working. The body of the toy is definitely durable if you have a bully breed. Both my dogs really enjoy it. Edit: 7 months later and this thing is still going strong. My doby loves it. It is tough as nails. Changed review to 5 stars.
