    Was searching for the o-ring that went behind the original cover when I stumbled upon this looked at the construction of it and said why not I am so glad that I bought this the construction is superb fits perfectly and has the reinforcement needed for the backflow preventing stuff it's a great product everyone should buy it.

    HPOP bolt cover

    Posted by Kevin on Sep 23rd 2023

    As always order processed & shipped right away! The cover is thicker and nicer than I expected, fit perfectly! NO more double wrenches and worrying about twisting the EBP tube mount off along with messing with sealant if the need arises to get at the HPOP bolt.. Very satisfied

    Works as it should, but could be better.

    I installed this on my truck about 6 months ago and when I went to take it off to replace my hpop, one of the stainless fasteners stripped out while trying to remove it. The idea of using a stainless bolt to replace factory is fine, but the stainless bolts being an Allen head that you can't grab with pliers is stupid. I ended up having to grind the head off with a dremel to get it off. A regular hex head fastener should be used for this part. Other than that, it is quite stout and makes removal of the ebp sensor and line a breeze as it's not flimsy like the stock piece.

    Looks good, stronger than the original, and comes with its own O-ring no silicone or other adhesive for mounting pretty easy.

    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.
