July 12, 2007I am looking at a 97' MAF Mass Air Flow Sensor. I am wondering if it will work on my 99'. Both GT's

July 12, 2007I don't think it would. It is calibrated for a car with non-PI heads.
July 12, 2007MAFs are not calibrated (that's an aftermarket term).
If the diameter of the MAF is the same, and the style of the pickup tube is the same (crossbar vs. a flow tube parallel to flow), and the connector is the same (meaning, no strange harness changes between those two years), then it'll work just fine.
July 12, 2007Looks similar to the stock one, has the same harness but is 70mm instead of stock.
i figured it would be a nice compliment to my 75mm TB.
July 12, 2007For $20 I think I should try it and see. Maybe I will get a little gain out of it.
What kind of power does it give, I have never changed a MAF out before alwasy just stopped with the TB.
the TB alone was a nice addition of power.
July 12, 2007It'll flow more air for a given MAF reading than your stock smaller one. For $20, I'd snap it up.
You will probably run a little leaner with this MAF for the first 10-20 miles or so, as the computer notices that it's lean all the time. It'll either learn to compensate with more fuel for a given throttle opening, or it'll throw a code for 'too rich' (hit the rich limit and the mixture is still lean according to the O2 sensors). If it throws a code, you can fix this with a chip. If not, it should eventually go back to the correct mixture after it learns that more air gets to the engine when you open the throttle, and you'll probably have a little high RPM power gain (minor).
July 13, 2007I guess any gain for $20 is good gain.
