# Fleece Performance 24-25 GM 2500/3500 Duramax L5P Secondary MAP Sensor Spacer

All new Fleece Performance MAP sensor spacer for the secondary MAP sensor on the 2024-2025 L5P 6.6L Duramax. Because of the direct placement of the MAP sensor into the intake air stream from the factory, soot buildup becomes an ongoing maintenance problem. This requires the sensor to be routinely cleaned or replaced. The Fleece Performance secondary MAP sensor spacer moves the sensor from the direct intake air stream to reduce soot buildup over time and eliminate the need to routinely clean or replace the sensor. Combine this with our primary MAP sensor spacer (FPE-L5P-MAP-SPR) for the highest level of reliability. Kit includes mounting block, fastener, and O-ring.
