Product Details

The Nitrous Express 20929-15 InstaBOOST EFI Nitrous System is specifically engineered to eliminate turbo lag in turbocharged applications. This complete kit delivers 35-150 horsepower on demand and includes a 15lb nitrous bottle. The system intelligently activates when boost is low, providing instant power to spool the turbocharger, then progressively tapers off as boost builds—allowing your turbo to take over seamlessly.

Key Features:

  • Adjustable 1-8 PSI pressure switch for precise activation control
  • Progressive ramping system smoothly transitions from nitrous to turbo power
  • 35-150 HP range eliminates lag even with large turbochargers
  • Complete bolt-on system with 15lb capacity bottle included
  • Designed specifically for EFI turbocharged engines
  • Cost-effective alternative to expensive anti-lag systems

Perfect for drag racing and performance applications where launch and low-end response are critical. The InstaBOOST system delivers instant throttle response and eliminates the dead zone between throttle application and full boost, giving you the benefits of a large turbocharger without sacrificing low-RPM performance.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

All seems great. Had item in stock as on there website and it was shipped quickly.

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
