Penray Introduces Plastc-friendly MAF Sensor Cleaner


2520 hands-on

Penray Inc. has introduced its new cleaner for mass air flow (MAF) sensors, part number 2520. While there are other MAF sensor cleaners on the market, this new formula is designed to be plastic-friendly.

It is well known that the delicate fine wire that senses the flow of air entering the induction system is subject to contamination. Dust, oily vapors, and other contaminants can collect on this very fine wire, forming a layer of insulation that can cause it to provide inaccurate information to the car’s engine management computer.

Results of a contaminated MAF sensor manifest themselves as rough idle, hesitation, poor gas mileage and, in many cases, the appearance of a Check Engine light. The cost of new replacement MAF sensors can run as much as four hundred dollars or more. So the use of an effective cleaning product is a viable alternative and a valuable service to the customer.

2520 Mass Air Flow Sensor Cleaner

The attachment point for the Mass Air Flow Sensor is usually a small plastic clip. Often aggressive solvents, like typical carburetor cleaners, can damage delicate plastic pieces. Penray 2520 is specially formulated to effectively clean the sensitive component without harming plastics, coatings or adhesives.

Use of Penray’s MAF sensor cleaner couldn’t be easier. The sensor element is typically accessed by unsnapping a few retaining clamps and lifting off a piece of plastic ductwork to reveal the fine sensor wire. This wire is very fragile; physically touching it is not possible without likely damage. Once the sensor is removed from the duct, several sprays of Penray 2520 will quickly dissolve deposits, so the full length of the wire is once again free of contamination. Newly exposed to the rush of incoming air, the sensor is able to perform its job properly and accurately.

According to Penray’s Mark Kardon, director of marketing, “Poor engine performance or degraded fuel economy can often be traced to a contaminated MAF sensor fine wire, especially when it reaches the point where it causes a Check Engine light to illuminate.”  Further adds Kardon, “Adding the use of this simple-to-use product to routine maintenance restores the performance of the wire and sensor, preventing the huge expense of a new sensor assembly.”
