GM Mass Air

Granatelli GM mass airflow sensors are replacement and performance MAF sensors for Chevrolet, GMC and Pontiac cars and trucks. The MAF sensor tells the engine computer how much air is coming in, so a dirty, failing or mismatched sensor can show up as poor idle, hesitation or a check-engine light.

This collection includes slot-in MAF sensors for GM LS 6.2L and 7.0L engines, Camaro and Corvette applications, the C7 Corvette and LT1 direct-injection engines, plus sensors listed for the LT1 Impala SS, GM trucks and SUVs, and the 3.6L V6. Several part numbers are offered in two versions (with and without a "-C" suffix), so check the exact part number before ordering.

Building a custom intake? Look at the universal 95mm billet slot-style MAF housing and the GM Series weld-on MAF saddle kit, which pairs a 350300 slot-in MAF with a 5-pin to slot-style GM MAF jumper harness.

How to choose: match your engine (LS, LT1, 3.6L V6) and vehicle in the product title, then confirm whether your setup uses a slot-in sensor or a complete housing. Shop Granatelli GM MAF sensors below.
