These clamps are exactly what I was looking for. I recommend ordering a size larger than the boot you are installing it over. Which I notice this recommendation was made in another post.
Great part, solid part. I will be ordering more in the near future...

Clamps are good quality. I should have gotten 3.5 inch instead of 3.25 inch to aid in installation. Very fast shipping

Better than stock, perfect fitment and they stay on ! Couldn't ask for more. Also very quick shipping. Will most certainly shop with this company again.

Great clamps for a great price.

The clamp was exactly what I was looking for. Works great and looks great

Snug fit initially and fit great. pair well with their boots.

A must if you purchase the Riffraff boots

These clamps are great for the price. I used the 3.25" clamps for my intake plenum and even though the worked good they seemed to be a little tight and I had to remove the nut and then squeeze them back together and re-install the nut after in place. If there was just a little bit more threads on the bolt these would have a 5 star rating.

Excellent clamps, manufactured by Breeze. Not spring-loading like Ford original. Size listed is maximum, you might want to buy a 1/4" larger to make it easier to slide into boots - I ended up having to remove the nuts to open the clamps completely in order to position on the riffraff boots.
