Throttle Body Spacers???
 

I have an '03 GT. I want to add a throttle body spacer. Which would be the best, a 1/2" Phenolic spacer or a 1" Motorvator spacer??? Also which pulley set is the best Steeda or March???
Any advice is much appreciated.;) ;)

I have the 1/2" phenolic spacer on mine. I got it off of ebay for like $20. The plastic spacers are going to be better because they don't dissipate the heat as much. As far as pullies go I have no experience with them, but I do trust steeda and have good things about thier pully set.

The Steeda pulleys are built very well and the crank pulley is one piece, not a piggy back pulley like many others. The crank pulley is also SFI approved as a bonus.

Yea I saw a PHENOLIC MUSTANG INtake spacer for like 20 bucks, are they worth it, they advertise 5-10 horsepower and up to 8% better gas mileage with better throttle responce, are they worth it?

Also I did a search as well and I'm gonna get one anyhow, are they hard to install?? Thanks

whats it do? if it works out good let me know 96_4.6... anyone else have input, im curious now... $20 mod with advertised effect? but on ebay, sounds more like a scam.

Makes sence though, raises the intake with the plastic cause it doesnt heatsoak as much so you get a cooler dense charge kinda, I'm gonna buy it and I'm not gonna be like wow I picked up .2 or somethin but every little bit helps

Which spacer is better though anyone know, plastic or aluminum??????

if you notice a difference, let me know please.
