🔋 Airaid Throttle Body Spacer 450-638 Review

I installed this gasket to eliminate the whistle coming from the throttle body on my 19 5.0 F150. When reinstalling, this sound disappeared, now I only hear noise related to transmission. I am very glad that the annoying nose is gone. Please note that it fits snugly on the air intake but has adequate room as the manufacturer claims it will not fit some CAIs.

If you have a Ford with a stupid 5.0 liter whistle (not a whistle but a high pitched tone) this will eliminate it! You have to install back. It is absolutely ridiculous that Ford Quality Assurance missed this and that it was considered an acceptable noise. Except that it's annoying. But thankfully, this seal eliminates the whistling noise. MY TRUCK is a 2019 F150 with a 5.0L engine and an original Ford whistle.

I installed this on my 2015 Ford F-150 not knowing if it was worth the money or not. Well I had it on my truck along with a K&N Blackhawk air intake and I can tell you that. My 5.0 is very responsive and the motor definitely gets more airflow. It also makes a whistling noise when cruising down the road at 1700-1900 rpm, and that sounds good. If you don't like it, just leave it in stock, otherwise don't complain. Obviously your pickup is not a standard V-8. money well spent
