Description

Introducing the all new Nostrum upgraded Direct Injectors for the Gen V LT V8 family!   The Stage 1 injectors are plug and play and flow 25% more than the LT4 injectors, enough fuel to support 1200 WHP on gasoline or around 900 WHP on E85, all without methanol or port injection!  

These injectors have an OEM equivalent spray pattern and are fully controllable with the factory engine management.  Each injector is individually tested for flow at operating pressures and dynamically batched into sets with very little variance to ensure the best possible experience! 

Nostrum backs all of their parts with a limited lifetime warranty.  All Nostrum products come complete with everything you need inside the box, including detailed installation instructions.  

NOTE:  2021+ Sierra/Silverado, Tahoe/Suburban, Escalade vehicles equipped with 6mm diameter injectors are not compatible, and cannot utilize these injectors without changing to standard diameter equipped cylinder heads.
