HOLLEY – AVENGER STEALTH RAM MULTI-POINT EFI FUEL INJECTION KITS
Holley’s Avenger Stealth Ram multi-point EFI fuel injection kit combines the bolt-on-and-go convenience of the Avenger EFI system with the Stealth Ram intake, which uses a tunnel ram design to produce impressive high-RPM power while retaining mid-range torque. The kit includes an Avenger ECU that’s easy to set up with the hand-held controller and actually self-tunes while you drive, selecting the best air-fuel ratio for performance and fuel economy. Holley built their excellent reputation on over 100 years of experience, which is why they’re one of the leaders in fuel delivery systems and the choice of every NASCAR team for the past four decades.
