Fixed whistle on 2012 f150
Fixed the anoying whistle on my 2012 f150. Very very happy about that. Only complaint is the price. Mine also came in black, I couldn't care less about color but some might.

2020 F150
Works perfect on a 2020 f 150 with the 5.0 V8 to get rid of annoying whistle sound. Must be installed backwards to do so

GOOD SPACER

Ford quality control sucks.
If you have a Ford with the stupid 5.0L whistle (not whine, but high pitch whistle) this will eliminate it ! You do have to install backwards. This is absolutely ridiculous that Ford quality control let this slide, and that this is considered an acceptable noise. Beyond annoying. But thankfully this spacer eliminates the whistle sound. MY TRUCK IS A 2019 F150 with the 5.0L with the authentic Ford whistle.
