Based on LR 6 ply silicone kit for stock intercooler pipe couplers 2 1/4" ID x 3"L would be the proper size.Brand name stuff is pretty pricey. Is there any reason a unbranded Ebay 4 ply reinforced silicone coupler with 2 301 SS T-Bolt clamps $7.04 Shipped. Junk? I know it's usually you get what you paid for.

Confirm the pressure rating of the inexpensive ones.

I bought the Lindsey silicone boost couplers because I knew it would fit and I wanted to support a longtime 951 vendor. I know that some people have had beefs with them for various reasons, but I have had nothing but prompt shipping and good service from them.

I do have the Lindsey silicone couplers. I switched them back to OE couplers. The OE ones are molded and fit perfectly. Silicone ones are just a tube. Since the silicone ones are a lot thicker I was having clearance issues. They will work, just not as well as OE.

HPS makes nice stuff. I use stock couplers with slightly above stock boost. Had the IC rubber coupler come off once. Cleaned it with isopropyl alcohol and put on a better hose clamp and no problems so far.
