Product images may differ from actual product appearance.

No Other MAF Sensor Gives You This Much Control

If you have a highly-modified 1985-1992 TPI Corvette, Camaro, or Firebird, this is the sensor for you. It's the only mass airflow sensor with fully adjustable calibration (via built-in screw) so high lift cams, big valves, nitrous, etc. are no longer performance tuning problems. The sensor provides up to 30% more airflow than OE, and you don't have to tear out the screen. Estimated installation time is 15 minutes using basic hand tools. Limited 90 day warranty.
