Description
The Fleece MAP Sensor Spacer with Boost Reference Port (FPE-L5P-MAP-SPR) is a precision-engineered upgrade designed for 2017-2024 Duramax L5P diesel engines. This spacer installs between the factory manifold absolute pressure (MAP) sensor and the intake manifold, creating a secure and reliable boost reference point without the need to drill or modify factory components. Ideal for applications requiring an external boost signal—such as aftermarket turbo controllers, boost gauges, or water-methanol injection systems—the spacer features a built-in 1/8” NPT port for easy integration. Constructed from high-quality materials to withstand high boost pressures and harsh engine environments, the Fleece MAP Sensor Spacer ensures a clean, professional installation while maintaining OEM sensor functionality and performance.

Installation
Problem: 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.
Solution: The Fleece Performance 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. The spacer block also integrates a 1/8″ NPT port to allow for installation of an auxiliary boost pressure sensor. Kit includes mounting block, fastner, sealring, and O-ring port plug.
