    I know that it's 80mm on the '01's and I don't think it changed from yours (99's).

    80mm for both the Cobra and the new Mach's.

    A word of caution though when I was at the dyno my car stock was running an A/F of around 13 throughout the entire RPM range. I put on an 85mm C&L unit and gained .5RWHP and 1RWTQ but my car ran WAY too lean A/F of 15! :notnice:

    I was running 93 octane and didn't notice any detnation (sp) but the dyno operator and myself about crapped when we looked at the graph. If your running rich your probally ok swapping out the MAF blindly. But if your tune is right on you need to retune your car for this mod.
