What is a MAF Customizer?
The MAF Customizer used in Custom Performance Engineering's MAFci Air Intake Systems eliminates the Check Engine Lights (CEL) that a custom after-market intake will create on a newer, more electronically advanced car or truck. While there are other "CEL eliminator" devices on the market, the Customer Performance Engineering MAF Customizer is specially tuned for YOUR vehicle to increase horsepower and torque along the whole rev-range!
