Airaid 350 532 PowerAid Throttle Spacer Review

Yes, there is a whistle. But not so annoying that it's unbearable. I couldn't tell any difference in engine performance. But it is installed and saved for a while.

Installation was easy and looks great. I didn't notice much of a difference in noise or throttle response on my 2014 5.7 Challenge. I cleaned the throttle body when I installed it, which I highly recommend as long as you turned it off.

It fits 392 HEMI (6.4) that just installed on my 2017 Jeep SRT, fits my upgraded 87mm perfectly -Throttle body and 4 inch bwoody air intake. In terms of performance it's hard to say as I have other upgrades but it sounds cool with the whistle it makes. Combined whoosh/suction intake sound knowing it's breathing under that hood for that 6.4 (392 HEMI).

Honestly the car feels the same as without the spacer. He had the same as without. However I just bought a throttle body with 90mm connections so maybe I should keep it to see what happens? I guess you never know. Also, the price is a bit high in my opinion. I have already bought CAI from Airraid. But I'm happy with it, so at least I got it.😆

Custom fitted for the 2015 Dodge Challenger R/T. Easy installation. A low whistle, not annoying if you just hate engine noise. Had one of these on my 2006 GMC Sierra Denali, slightly increased gas mileage, had it on the truck for over 5 years. Just installed it on a Dodge so can't comment on increases yet, pair it with a Specter air intake. Let's see if that MPG increases in the coming months.

Since I cannot give this product negative 5 stars, I give it the lowest rating. This product absolutely sucks! This did not result in an increase, on the contrary it reduced throttle response, tq and hp. Before I put this pad on my 08 RT Charger had great throttle response and was pretty quick thanks to my CAI and setup. After installing the spacer, my car was stock again, albeit with an annoying whistle. Even after the reconfiguration, the car remained in stock. After removing this POWER THEIF
