About this part

Product Details

Nitrous Express is known for their nitrous oxide systems, and their Instaboost EFI Jet Pack is a prime example of their focus on performance. This jet pack is designed to help you get the most out of your EFI nitrous system by ensuring precise fuel and nitrous delivery. The jets are manufactured on CNC equipment, which means they hold a very tight tolerance, guaranteed to be within .0005 of their specified size. This precision is key for consistent performance and reliable operation.

What sets these jets apart is their internal design. Instead of just being a simple hole, the NX jet features a contoured inlet and a multi-stepped outlet. This advanced internal shape is engineered to allow for turbulence-free flow, meaning you get more nitrous oxide passing through the same orifice compared to standard jets. In testing, this design resulted in up to 35% more flow, which can translate to a noticeable difference in your engine's performance when the nitrous is activated.
