Product Information
Holley Sniper EFI XFLOW fuel injection systems are packed with four 120 lbs.-hr. injectors and 900 cfm of airflow.
These EFI systems deliver enough airflow for 800 plus naturally-aspirated horsepower, and work great with CD ignitions. They feature contoured entry corridors for maximum breathing potential, and the dual-pattern mounting flange makes these true bolt-on replacements for any 4-barrel carburetor.
