Does a bigger MAF give you more power? May 16, 2008, 11:53:53 AM So my question is will upgrading to a bigger (ie 70-76mm) MAF sensor really give me any noticeable power gains? From what I've seen on dyno tests of stock cars a MAF upgrade adds maybe 3-5 hp, not enough for me to actually feel. I just don't want to spend $130 on a C&L 73 mm MAF and be underwelmed when I could have spent the money on something else for the car. I'm guessing that the stock 55mm MAF I'm running might be costing me a couple of HP on my combo but really when I put my foot to the floor the car runs just as fast if not faster than it did when it was SD.

A lot of people have idle issues and lean spots with the aftermarket MAFs, because they don't have very good transfer functions compared the Ford MAFs It's not worth the couple of HP on the top end to have drivability problems.

That one seems to be the best option to me if I went with an aftermarket MAF.That's the route I took when I converted over to MAF. C&L meter with stock electronics. Runs great with no issues. There really is no sense in having a smaller air meter compared to your bigger throttle body. Get rid of that bottleneck area and be done with it. Quote Selected

Works perfect!Some guys will say too big is bad. This goes for throttle bodies as well. It's debateable as shown HERE Whatever the case You should try to run a MAF housing at least a hair larger than the throttle body.I MAY be making a change myself in this area shortly. 80mm MAF & 75 mm TB. Not sure yet though. I'll be doing a custom chip if it happens. Quote Selected
