Fits perfect and looks great, nice pop of color under the hood.

Good machining

I actually ordered all three from Clay and they are not the cheap plastic that Ford uses these are quality products. I also have the blue matching boots and they match up with the three caps very well. Easy to install. As with everything else I've ordered from RiffRaff they shipped and were received right away.

Great craftsmanship and fitment. I have the blue and red for my 7.3s.

These are great as are all of Clay's products!

I also have the Sinister billet cap which are great as well, but I feel that these are of the same quality at a much better price and are offered in several more colors.
These add a nice touch to the engine compartment. Now if we could get the billet plenums in Orange as well, I would be set. My normal preference would be either black or red as a black/red theme is my preference, but the orange is very nice for something a little different.

Other than that, not much else to say. These utilize the factory cap providing a billet shell.

Highly recommend for those that like to add a little color to the engine compartment

Really great machining and the blue anodizing looks great. Easy install, no leaks. I recommend them to anyone with an OBS truck.

I am always looking to find a way to set my truck off from others, and this is a perfect way to do that. And you can't go wrong with the fact that it's made in America. Fit and finish is on point, as is everything else I get from Riffraff.

I debated for days which color to get. I went with red and am super happy with it! My only disappointment is there is not a matching Degas Bottle.
