Some L5P 6.6L Duramax vehicles have a secondary MAP sensor. The problem: Its direct placement into the intake air stream from the factory causes the soot buildup to become an ongoing maintenance problem, requiring routine cleaning or replacement of the sensor. The solution: Fleece Performance secondary MAP sensor spacers. They move 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. Each kit includes mounting block (spacer), fastener, and O-ring.
