K&N Ram Pod Filter for MAF / MAS Sensor vehicles.
Certain models of the Mitsubishi range run the Mitsubishi MAS / MAF sensor which is an the electrical metering unit that goes after the air box. This unit reads how much air passes through the unit via ultrasonic waves and is a oval shaped unit. One of the major problems we see is the fitment of universal Pod Filters which then start creating problems with idle or power by running rich, stalling etc.
The reasoning behind this is the honeycombed section requires the air flow to be very straight and clean in order to be read correctly. Generic pod filters are cone shaped and instead, causes a swirling action which causes the MAF Sensor to misread the airflow, especially at light to medium throttle loads. Additionally many of the adapters fitted to the MAF / MAS sensor are either square and cut off some of honeycombed section in order to bolt on the round pod filter, or are only approx 1/3rd the actual diameter of the MAF Sensor restricting airflow.
To combat this RPW has imported in from the USA specific K&N filter charger kits that are 100% compatible with the MAS sensor without causing problems. These are flat oval shaped filters with a proper cast adapter.The adapter and filter provides airflow to 100% of the MAF Sensor area for very accurate readings.
To quote a common term : If K&N believed that a universal filter would do the job why did they make a specific filter for the Mitsubishi Air Mass Sensor.
These are guaranteed to not only improve the power of your car over any other filter design, they will not cause any running problems and are our recommended first modification to the vehicle, even before the exhaust.
This has been tested time after time again, we see at least 1 – 2 vehicles a week coming through our workshop where we replace there “Universal Rampod” with the specific K&N unit and the car immediately idles better, pulls harder and provides better fuel economy.
This is not supplied with any mounting brackets, these will be required to be made on the vehicle when installed. We recommend for most vehicles, to retain the front half of the original air box to act as a heat shield from the exhaust system where this is located in the stock air box position.
