Fleece Performance FPE-L5P-MAP-SPR MAP Sensor Spacer & Boost Reference Port for 2017-2024 Chevrolet/GMC (6.6L)

Fits select 2017-2024 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD trucks equipped with the 6.6L L5P Duramax diesel engine.

On the factory L5P Duramax intake, the MAP sensor is positioned directly in the intake air stream. This exposure leads to rapid soot accumulation, causing signal interference and requiring frequent cleaning or replacement of the sensor. The Fleece Performance MAP sensor spacer solves this by relocating the sensor away from the direct air stream, significantly reducing soot buildup and maintaining accurate boost pressure readings over time.

In addition to extending sensor service life, this spacer features an integrated 1/8" NPT port. This allows for a clean, secure installation point for an auxiliary boost gauge or manifold pressure reference without needing to drill or tap factory components. Manufactured for a precise fit, it installs using standard tools and factory mounting locations.
