I was at autozone today and saw tese spacers thougt id buy one, they had none that fit my car but I want to know about them.I heard they make a s/c like sound. Is it loud? and hp increase?

 

Sold at AutoZone and makes a supercharger noise. What do you think? honestly for our applications they do nothing. Some applications they will gain horsepower by reducing the swirl of the air. Some applications. Dont waste your time, money and potentially your warranty

(My Opinion based on facts)

 

My roommate has one from UPR and he says he can tell a difference. No s/c sound though.

 

From all that I've read,it's all hype. No gain except in someone else's pocket.

 

I have on my maxima and I could tell a difference. Not sure about stangs though

 

Yeah see it really is like application based. I have seen dyno "proven" results from people who did a before after and gained horsepower in the 5-10 range. and also my friends works at a dyno shop and the guy came in with it on, they took it off and it gained 8rwhp. That was on a charger I think. I think there is better places to spend the money for the mustang.

 

They are useless. TB spacers are relics of the days of carburators and TBI.

100% useless

 

Are you for real?

You should not be driving a Mustang if you are, sorry.
