I've seen the throttle body spacers on Ebay ranging from 15 - 30 bucks. Are they worth it or not?

I've read the archives regarding underdrives and gears. Where's the best place to grab a set of 3.73's from? How bout pulleys...Steeda or FMS? Where?

Here's the stupid question of the day...the BBK cold air kit goes right into the fenderwell. Where is the air filter? There's not one in the fender well. Is it supposed to be like this?

Any help would be appreciated. Thanks

Interesting post! The TB spacers work...they are good for 2 hp or so. So, they work, but not much. Part of your problem IMO might just be the 70 mm TB. You need to either have your stock plenum ported to work properly with that 70 mm TB OR purchase an after-market plenum. If you decide to port the plenum, then definately buy a spacer. Ported plenums and spacers work great together. After-market plenums do not need spacers.

With either of the above changes, you might free up as much as 15 hp especially if the 70 mm TB is costing you a few ponies. Car will have better throttle response and breath better at higher rpms.

UDP's and gears are great mods! Adding the plenum, a set of 4.10's, and UDP's will free up 15 - 25 hp and the 4.10's will feel like you added 40 hp. You will have a new car! Get Steeda UDP's.

www.mustangtuning.com is a great place to buy mods. They also have a forum.

BTW, the filter should be in the fenderwell as already mentioned.
