PPE MAP Sensor Relocation Block (Lower) 23-26 GM 6.6L Duramax

Is your L5P Duramax starting to lose consistency, throw off boost readings, or suffer from a soot-contaminated sensor? The PPE Lower MAP Sensor Relocation Block is designed for GM owners who want to keep critical manifold pressure data clean, accurate, and unaffected by modern emissions systems. By moving the MAP sensor out of the direct path of exhaust soot, oil vapor, and intake contamination, this simple billet upgrade helps restore proper sensor readings, protecting drivability, throttle response, and fuel efficiency on trucks that work hard, tow heavy, or run performance tunes. Whether you’re chasing cleaner data for tuning or just trying to keep your L5P running as it should from the factory, this is a smart preventative upgrade that eliminates a common weak point before it becomes a problem.
