Great quality, definitely worth the replacement of the old factory ones while I was in there.

Get these with the CAC hose kit, clamps and billet Plenums - you'll never have a worry again!!

while converting my E99 to L99 these boots were a necessity. I have ran Riffraff boots for many years now and have zero issues. Thanks for another great product.

Along with RR plenum inserts and T Bolt clamps, my boost leaks are history. These boots are a little taller than my old ones, which made me feel a bit more confident with the clamps. Nice and sturdy. Highly recommended.

These things are well worth the money, they are overbuilt. The factory boots were oil soaked, worn out and flimsy. These are strong, thick and built to last.

As with the upper intercooler boots, the stiffness of these requires patience and quite a bit of Tetris skill to get the X pipe into position. But once in all the boost leaks have ceased.

Good fit and looks great at a good price

Much thicker and heftier than the stock junk. My Only problem was with the limited space on my E350. This should be an automatic replacment for everyone. If your in there working. Get these, the inserts and new clamp, do it once and do it right!

I recently purchased this product, the site is easy to navigate and shipping was top notch. I definitely will be ordering from this site again.
