Had already put the new boots on. But, with a WW2 and the stock plenums and wormgear clamps, I was still seeing oil all over my boots after a short drive.

Got these along with plenum inserts (so I don't crush my plastic plenums) and riffraff boots. All combined = no boost leaks. Highly recommend the 3 as a combination.

Tip: Pay attention to the size of the clamps. They aren't all the same. A couple will be meant for your larger tubes going in/out of the Intercooler.

Tip2: Hang on to those extra T-bolt clamps you took off your tubes (throw the useless wormgear ones out), you may want these for doubling-up clamps in the future if you are generating huge boost.

The up side, there are a very quality product and fit perfectly! It solved my leaky boot issue perfectly and the truck is running better now. Caly shipped the same day I ordered them and they look great under the hood. I went with the blue colored boots and since I had time to kill did the foil delete and painted the pipes red. Nice touch of color to the engine bay.

My only gripe is that is was very difficult to install the Y pipe to the boots from the intake manifolds and took a lot of time to complete. Tried a few different approaches and finally got them on. That aside, I would strongly encourage anyone shopping for boot to buy these! They are a really good product.

Put these in with my new boots from riffraff. Awesome fit
