GT500 Slot Style MAF
Every custom tuner has fought with MAF meters that don't work, are calibrated incorrectly or peg at a certain HP level. The OEM 07-10 GT500 MAF meter is the solution. It will support up to 825RWHP in a 4" tube without the use of a MAFIa, will NOT PEG and is direct replacement for all 2005+ Ford Mustangs, any 99-04 car using a slot style MAF housing & 2004+ F-150 Trucks! OEM Quality Calibration for factory driveability, repeated accuracy, and reliability.
GT500 Slot Style MAF Meter
Supports 400rwhp - 725rwhp with Centrifugal Blower Applications
Supports 400rwhp - 825rwhp with Roots Blower Applications
Supports MORE with a Larger MAF HOUSING and the use of a Diablosport MAFia
For customers with 99-04 mustangs this MAF meter will require a MAF housing designed to work with slot style MAF meters as well as the LP-MAFHARNESS pigtai. The pigtail is used to adapt your older style plug to the new slot style connection.
*Works excellent for 2003-2004 Cobra owners using the Whipple Crusher 123mm Intake Setup.

Our steel flange allows the 05+ sensor to be installed directly onto any size tube. The flange must be attached by welding. The radius on the flange is cut for 3.5", but welding will fill in any small gaps present when used on other tube sizes.
If you are not able to weld the flanges on take a look at our billet MAF housings.
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 receptacle for the sensor.
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 vehicles). The slot style MAF provides a very clean and consistent signal when used in blow-through. The slot style MAF can be placed in any size tube, from 3" to 4.5". We do not recommend going smaller than 2.75". In blow-through applications a 3" tube will result in the best signal, 3.5" tube will result in a marginal signal, and 4" will result in a very poor signal when used in blow-through. The car will need to be properly tuned for the new MAF sensor housing size.
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 recommend suck-through, but this has since changed with the introduction of the 05+ MAF. With blow-through the by-pass valve can now be vented to atmosphere, this will reduced air temps, because the air is no longer being re-circulated and re-heated.
Running the MAF sensor in blow through in a smaller tube than stock reduces range, to get this range back you can use a MAFIA extender or an VMP HPX slot style sensor. For very high power applications the VMP HPX sensor is recommended, as the MAFIA can only be used up to setting 3 on the 05+ MAF.
