KEEPS YOUR MAP SENSOR CLEAN

Your engine’s EGR (Exhaust Gas Recirculation) and PCV (Positive Crank Case Ventilation) systems draw unburnt exhaust gasses and oil vapor into the combustion chambers to lower combustion temperature, reduce NOx, and keep harmful gasses from entering the atmosphere.

LESS CLEANING.
MORE POWER.

This recirculated exhaust gas and sticky oil vapor adheres to the MAP sensor’s delicate electronics causing inaccurate readings. This results in incorrect fuel calculations reducing fuel economy and power output.

EASY INSTALLATION

Requiring only a minute or two to install, Banks MAP spacer eliminates the need for periodic cleaning. It protects your sensor from faulty readings, ensuring proper air-fuel ratios are always calculated by your Duramax’s ECM.

With a machined logo, show your Banks pride while extending your sensor's cleaning or replacement intervals.
