so does n e one know how much a high performance mass air flow sensor REALLY helps....i need a new one and im just checking if its a good idea or not....the performance one i know of is like 435 dollars and the stock one i found is $256....help me please

 

The best buy is a WELLS Maf p/n SU-145. Better design then stock and also higher flowing, more then the ECM can calibrate. Cost about $156
