Mass Air Flow Sensor Reviews

Has anyone installed or know somenone who has installed and tried a Granatelli Mass Air Flow Sensor on a 2004 Grand Prix 3.8L supercharged with a K&N cold air induction and 3 in exhaust?

I definitely felt the K&N mod as it made the throttle response more linear, and not so jumpy when the supercharger kicks in. Fuel economy went up about 7% as well!

I would like to know if adding a Granatelli MAF will also step up the performance and improve fuel economy? Do you think its worth the $300 or so spent? I drive 70 miles round trip to work.

on what car....this is a really general question, as it may help on some cars, and may not help on some cars

Like NYer said, it depends on your car. If it's your first mod to a stock car, there are probably more cost-effective ways to gain performance. If you are really modding a car, eventually the stock MAF may have to go, and I've never heard a quality complaint about Granatelli (sp?). Keep in mind that an aftermarket MAF will probably give you a 0-10hp... not enough to feel.

Depends on application. The MAF is a supporting modification that is meant to be tuned to the ECU/Injector set up. Bolting on a larger one will most likely throw off the AFR for a while until your computer compensates for you provided the O2 sensors aren't hurtin.

Lol, once again depending on what car. I definately felt my intake in the higher RPM, and that was only 5 horsepower...MAYBE

You may feel better throttle response, or some other increase in performance, but even in a lower hp car I highly doubt your ass is sensitive enough feel 5hp. Think of it this way, a loss of 5hp is probably equivalent to having a person sitting in the car (extra weight). Can you really feel the difference in acceleration?

Actually, K&N claims a 15 HP gain. And yes, you can feel it on a 3.8L V6, 260+ HP supercharged engine. Its definitely breathing easier. Maybe the K&N cold air induction enhanced the 3" exhaust I installed.

Incidentally, I ordered the Granatelli MAF for $249 from JD's performance. The price was right, so stay tuned for the results.
