SLP Mass-Air-Flow Sensor, 1998-00 LS1 High-Flow

SLP's high-performance 85mm mass-air-flow sensor flows a whopping 895 CFM (90 more than the stock 75mm MAF)—enough to improve engine output by up to 10 horsepower. Or, remove the screen (not recommended on street cars) for an incredible 1000 CFM of air flow! This lightweight composite unit weighs one pound less than the factory MAF and is fully capable of supporting engine applications making over 600 horsepower. Compatible with stock and modified engines.

NOTE: For use with stock PCM tuning.
