i have a 97 and i jus took the air box off and put a filter and i was wondering if i put a throttle body spacer would it make it whistle? thanks

Ty

spend the 100 bucks on something else, they are the spacers are only good for making you wallet thinner, and holding down papers.

lynn97

have u ever tried one ?

Ty

I have not personally bought one, just because I would rather spend the 100 bucks on something usefull.

just my .02

Yes it does... it whistles on mine.. but not as loud.. getting a cold air intake will make it whistle even more because of the larger diameter pipe and open filter... which is what I am going for.. but it does... and it does work for $100.. i went from 13mpg to 16mpg.. 18mpg with the K&N drop in filter

Ty

what motor? were the gains all down hill, lol

lynn97

Well... its not 18mog... more like 16mpg... with the 4.6L powerplant.. but the spacer and the filter..

My brother's 97 w/ 4.6 and spacer does whistle. BTW, he's also running a K&N 77 series. As far as gains, can't really tell. We did headers, cat-back, and spacer all at once. There were big gains, but how much from the spacer??? Can't say for sure.

as far as the spacer.. there really is no power gains.. i have it for saving fuel and for the cool whistle sound.. but the k&n drop in filter is wht made a difference
