Product Description
Fix common boost leaks and MAP sensor sealing problems with the WEHRLI CUSTOM FAB WCF100796 MAP SENSOR SEAL & BRACKET designed specifically for 2006-2010 LBZ and LMM Duramax engines. The factory MAP sensor seal often deteriorates over time, allowing boost pressure to escape and causing inaccurate sensor readings, reduced performance, and potential drivability issues.
The Wehrli Custom Fab solution replaces the weak factory seal with a high-quality upgraded seal and a precision-machined bracket that securely retains the MAP sensor in the intake bridge. This simple yet effective upgrade prevents boost leaks while ensuring the sensor remains properly seated for accurate pressure readings.

Frequently Asked Questions
What problem does this MAP sensor seal fix?
Over time the factory MAP sensor seal can deteriorate, allowing boost pressure to leak from the intake bridge. This kit restores proper sealing and prevents boost loss.
Will this improve engine performance?
While not a power-adding modification, it ensures the MAP sensor receives accurate boost readings which helps maintain proper fueling and engine performance.
Is this a direct bolt-on installation?
Yes. The kit installs using factory mounting locations and can typically be installed in minutes with basic hand tools.
Is this a common Duramax problem?
Yes. MAP sensor seal leaks are common on LBZ and LMM Duramax engines due to heat cycles and age of the factory seal.
Do I need to replace the MAP sensor itself?
No. This kit only replaces the seal and adds a secure bracket to retain the existing MAP sensor.
