Avoid Fouled MAP Sensor

“The Banks Map Sensor Spacer Kit is a very simple install, and it gets your MAP sensor out of the way of the flow of soot, so you won’t have to clean it so much,” explains Percy Reynolds recently on his Duramax-focused YouTube channel. The installation took about 5 minutes, and now he has a sensor that is out of the contaminated airstream, ensuring constant power and fuel economy.

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. 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. The Banks MAP Spacer is the attractive, easy way to prevent this oily soot from building on your MAP sensor by relocating it up and out of the contaminated exhaust stream.
