    Worth it!

    Huge improvement over the factory cover. This cover is much more substantial that what is visible on the posted pictures. The rear has an excellent resealable quad ring to mate to the timing port and the hpop cover. And the rigidified exhaust back preasure sensor bracket is greatly appreciated . No more cranking and tortioning that tin flange trying to get your sensor and line loose . Another great riff raff product. Form meets function on this one.

    Top notch 100% Made in America Billet Aluminum quality part! If your thinking about purchasing this product, do it! Awesome little upgrade to the appearance and function to your HPOP Access Cover. Fits the sensor perfect and looks awesome.

    after having this installed, I also noticed that the crossover pipe was pretty clogged as well after installing this and cleaning the cross over pipe m,y 7.3 runs a lot more smooth. This is a lot better product than the OEM one

    Awesome product! Excellent machining and a perfect fit! Definitely purchase the tube, fitting and a new sensor! You will ruin the tube trying to remove it to clean it. These beasts are old. Do it once and do it right!

    Blows the OEM AWAY!!

    If you are on the fence about purchasing this, then consider this me blasting you off that fence, because this thing is AWESOME!! Piece of cake installation (relatively considering the spot you have to put it), thick, durable material with a fatty o-ring means no messing around with RTV getting all over the place. All of that and you get to chose what color! I got green :) So what are you waiting for?? Get it now! Your Powerstroke will thank you!

    New Hpop bolt cover who dis?

    Posted by Benjaman on Feb 20th 2022

    Found I needed a new Ebpv sensor and tube whilst installing some other quality goods from riffraff so I went ahead and ordered one of these bad boys in green and it’s a shame it’s buried so deep because she’s pretty but aside from that I highly recommend so if you’re in the market, do it! It even makes installing the tube and sensor easier than stock, another beautiful piece from RR

    Best replacement cover. Replaces that old piece of junk original part. This part is much thicker and stronger. Adds some style as well. Very easy install
