Water/methanol injection effectively lowers intake air temperatures and increases octane levels, allowing for more aggressive tuning and increased boost pressure in forced induction applications.

Key Features:

  • Water/methanol injection reduces intake temperatures by up to 100°F
  • Increases effective octane rating and prevents detonation
  • Allows for more aggressive ignition timing and boost levels
  • Complete system includes pump, controller, and installation hardware

This system provides a cost-effective alternative to race fuel while delivering the cooling and octane benefits needed for serious performance builds. The progressive controller ensures proper injection across the RPM range, maximizing power gains while protecting your engine from damaging detonation.

A+shipping was quick, communications were quick

Good price over the product manufacturers web site, but item went up $18 since I found on this site last week. After receiving the Nfab nerf bars, I was disappointed in the overall fit and finish of a $300+ product.... Installation took very long because

Best prices online! Ordered a JBA performance exhaust and Airaid intake system for my 06 F-150. Was hesitant at first because I never heard of them but ordering was a breeze and saved me over $100 total for two items compared to anywhere else. Had package at my door in about 24 hours and even selected normal UPS ground shipping. Very satisfied and will definitely return!

Autoplicity was plenty cheaper than competitors for the springs I needed. I was shopping around and left the website after beginning a transaction and they sent me a coupon for 25% off shipping if I would return and purchase from them, which was cool. Unfortunately the coupon code didn't change the price and I didn't receive 25% off, but it was still cheaper than others.
