throttle body????

[svo978]

I was wondering what size throttle body and MAS air sensor should I get for my 99 gt? I am ordering an intake plenum, but don't know which size to get of either. 75tb and 85mm mas air????????

i have the 75mm accufab TB on a Trick flow Plenum with the stock Mass air. The combo works great!

Are the bigger MAS air sensors better with an intake combo or is the factory one enough?

Keep the OEM one (wishing we still had the OEM one to switch back on my wife's 01). My C&L MAF is collecting dust. The aftermarket MAFs typically aren't any larger than OEM, but flow a bit more freely. the net result of this is (since it uses the stock electronics) is a lean condition, which does make more power, but unreliably and unsafely when mixed with other aftermarket parts and without a tune.
The 85mm MAF, by the way, is for 02+ GTs, the same time Ford increased the MAF size. The 80mm MAF is for 01- GTs. Don't feel shortchanged though, as this is NOT a limitation for your motor. Either OEM MAF is good for 400HP+.
I've got the Accufab Plenum and 70mm TB - these are simply the best pieces, albeit the most expensive. The cost per HP is high, but the quality is great. Take a look at the plenum showdowns at modulardepot ---> http://www.modulardepot.com/?show=articlesdet&aid=30
and

Your best gains will be the basics - full exhaust (long tube headers, midpipe, catback), K&N filter, underdrive pulleys, and of course throw in some 4.10 gears...and add a short shifter and you'll be having fun!

I bought a 75mm BBK throttle body and a 90mm Lightning MAF for mine.....but I'm also running 9psi or forced induction too. You won't need any more than a 70mm T/B and an 80mm MAF for most N/A set ups.
