Looking to add a little extra performance with a fairly small budget lol. Any thoughts or experience with throttle body spacers?

Have one on my Tundra, but sadly it has a bit of a whistle.. Kind of scared to put one on the Jeep!

Not so concerned about the whistle I know that is common, but was there a noticeable difference in performance or mpg

Never used one but I've read a lot about them on this forum (try doing a search...you should find other threads)...

Basically...you get what you pay for. I wouldn't waste the money . I haven't heard many good things tbh

I have one on my jk,. when doing my research I read alot of negatives about it and was skeptical about purchasing one, but those reviews where mainly on the guys with manual jks,. the reviews on those with autos where alot better with gains on mpg and abit more pep on the pedal so I went for it and did notice it, its not much ,. but noticeable and u do get the whistle which dosent bother me

I have one and the whistle drove me nuts so I removed it. Didn't really notice any increase in mpg. But I have a very heavy right foot.

I've had plenty of turbo cars with loud intakes and blow off valves so as long as its not louder than a turbo spooling up or blow off valve popping off, it won't bother me at all

Yea there was a quicker pedal response and I gained a little more HP..

They've done test on this and there is no gains with only a tbs.

Installed one on my 2012. Not any noticeable power but did gain on the MPG. Maybe a little throttle response but nothing huge.
