do NOT put a filter at the opening of the oem sensor. at least have a pipe that goes behind the headlight. and better if it goes somewhere in the fender. you can FEEL the difference it makes with the filter right on the sensor....and by FEEL difference i mean feel SLOW...

 

would you mind going into detail about placing an open air filter in a place other than next to the OEM AFM.
Would open air by the AFM be worse than the closed box?

 

I think it has something to do with air turbulence. Having a long and straight pipe before the sensor will smooth the air flow and increase the accuracy of the readings.

 

understood.
Thanks!

 

Hi All,

We do both chips for all 944 models and a MAF kit for the 944. The chips are available for:
924S 2.5 85.5 on (24pin)
924S 2.5 88 (28pin)
944 2.5 85.5 on (24pin)
944 2.5 88 (28pin)
944 2.5S (28pin)
944 S2 (28pin)
944 2.7 (28pin)
968 3.0 (28pin) x 4 options (USA & ROW specific with choice of RPM limits)
944 Turbo, we have numerous options for - details available if required.

NOTE: early models need an ECU change to use a plug in chip.

We have a MAF kit for the 944 and 944S/S2. Retail price is £999.95. The Rennlist promo price is currently $849.95. The 944 n/a kit (for 8v models) requires a 3.0bar FPR to optimise (about $50 USD). Expect more drivability, better torque spread and improved throttle response. Power gains are about 12bhp - but torque gains are 15-20lbft. Car needs to be in good shape with no vacuum leaks and good compression to respond well. If the car is in good shape, results are very obvious when driving and enhanced further with our MAF chip (a $145.00 USD option, does not require 3.0bar FPR if fitted)

More details here: http://www.promax.uku.co.uk/maf_kit.htm

The 944 n/a uses a smaller diamater MAF. 944S/S2 models use same MAF as 944 Turbo and 911 3.2/964.
