Protect Your Sensor Before It Becomes A Problem

If you’re running a 2017-2019 Duramax and haven’t already had MAP sensor issues, consider yourself lucky—but that luck doesn’t last forever. Soot buildup from EGR flow is a known problem, and it clogs up your sensor faster than you'd expect, especially if you're towing, idling often, or driving in dusty environments. That’s where the S&B MAP Sensor Spacer Kit comes in. It’s a simple but smart fix that moves your sensor just far enough out of the soot stream to keep it cleaner, longer. The result? Fewer CELs, more accurate readings, and better engine performance over time. It installs in just a few minutes with basic tools, so you can knock it out in the garage without tearing the truck apart. It's one of those small upgrades that pay for themselves just by preventing a bigger headache down the road.

Engineered To Keep Your Readings Clear And Clean

The S&B 82-1000 MAP Sensor Spacer Kit is precision-machined from billet aluminum and finished in a protective black anodizing for long-lasting performance. It's built specifically for 2017-2019 GM 6.6L Duramax L5P engines and fits directly between the intake and the MAP sensor. By relocating the sensor slightly out of the direct path of recirculated exhaust gases, the spacer significantly reduces soot accumulation, helping to maintain accurate manifold pressure readings. This is critical for maintaining proper air-fuel ratios and ensuring the truck’s ECM responds as it should under load or during acceleration. The kit includes a new O-ring, screw, and threadlocker so you don’t have to chase down extra parts before getting started. Installation is quick and doesn’t require any tuning or advanced mechanical knowledge. It’s a simple, effective way to protect a critical sensor and preserve long-term engine efficiency.
