PMAS - 86-04 Mustang GT & Cobra 05+ Style MAF Conversion Kit for 86-04 with HPX

In 2005 Ford Introduced a new style of mass-air sensor. It is commonly referred to "slot" or "card" style. This sensor has no housing, the stock airbox has a receptable for the sensor

We offer two packages to convert to the 05+ style sensor. One with a stock Ford MAF + Diablo MAFIA to get the range back, the other package with an HPX PMAS slot style sensor and connector harness (no MAFIA required).

We have found that the new sensor works very well in blow-through applications. Blow-through means that the mass air sensor is placed after the compressor (supercharged or turbocharged cars). The slot style MAF provides a very clean and consistent signal when used in blow-through or suck through. The slot style maf can be placed in any size tube, from 3" to 4.5". We do not recomend going smaller than 2.75". The car will need to be properly tuned for the new MAF sensor.

When it comes to driveability and throttle response, blow through with an 05+ MAF is the best way to go. Having the MAF sensor far away from the engine makes the car harder to tune and hinders throttle response. In the past tuners used to recomend suck-through, but this has sinced changed with the introduction of the 05+ MAF. With blow-through the by-pass valve can now be vented to atomsphere, this will reduced air temps, because the air is no longer being re-circulated and re-heated.

We now offer a complete package with everything you need to convert. Recomended for Procharged cars and other cars with air to air intercoolers.
