I was reading the comments on their website and thought it was hard to beleive. Some said they just changed the air filter and began to seen big results. Will Putting one of these in do anything for my stock 98 GT?

 

It will help a minimal amount. It would probably net a couple hp.

 

The only thing that will make a noticable difference on our 98 GTs is gears, PI Head Swap,forced induction or spray it. We have the slowest GT of the late model stangs.

 

No, you wont notice it, you just have to decide whether the 50 bucks is worth it to not have to change the air filter ever again.

 

You might get 1- 1.5 hp out of it, depends on how bad the filter you have in it is.

 

obviously you never owned an 80's GT

 

i read something about underdrive pulleys are they worth the money? The car is actually my dads i was looking for something to get for him to help improve his cars performance a little as i am not old enough to drive.

 

This would be the best thing to do look here

 

no no no the 96 is the slowest. trust me.

 

What if I installed this cold air intake http://www.mustangtuning.com/mugtv8pocoai.html
ANd these underdrive pulleys

Would this do anything? And does anyone know that the top speed of a stock 98 Gt is? Also could someone give me an estamite on getting the gears changed?

 

depends on location. gears might not be the best depending on how much he drives. the pulley's and cai will make a little diff. it's really on what you have to spend and what direction he is goin on the car.

 

forget the CAI, just buy a K&N.

call march, and see if the damper is SFI approved, if not stick with steeda.

actually I have a sett of 96-00 steeda pullies and timing adjuster I will sell for 200 shipped
