Installed this a couple weeks ago in my 2000 7.3 and went in easy. Unfortunately, haven’t noticed any change in the sound like I was hoping for but I’d still do it just for the potential savings of my injectors.

I am thoroughly impressed with the fit and quality of the part, helped my idle as stated, and seems to have better throttle response as well.

Made my Early 99 7.3L nice and quiet at idle, even my wife noticed it. Better off idle response as well.

Easy enough install and quieter motor.

Great quality

Very easy to install fits perfectly.
Straight away noticed smoother and quieter at idle . Even cruising on hwy noticeably quieter very good quality product that works .Thanks riffraff.

Excellent quality on this...

Great product for the money and smoother idle

Ok so I heard about the oil crossover and read reviews and what not. It says it quits the ole u.3 down a little and I figured ok well I dont want a quieter truck but it sure cant be bad for oil to crossover more easily. That being said it was a top notch part and extremely easy to install, I like it so much I bought a total of 3 for all of my trucks! I gotta had it to riff raff quality parts at quality prices and I have ordered numerous parts since then.
