HPS HTSC-400-BLK Silicone High Temperature 4-Ply Reinforced Straight Coupler Hose, 65 PSI Maximum Pressure, 3 Length, 4 ID, Black

This is not a coupler. Its the exact same size as 4 other pieces. So it dont work with other 4 parts.

Good quality however it did not fit, the problem was I took someones advice and bought the size they recommended.... They were wrong, so I bought the correct size and love it.

Used this on my LLY Duramax to replace my 4 rubber plumbing coupler on my LBZ turbo mouthpiece. Used the hose clamps off that and it gives me peice of mind with this silicone peice that it can stand up to the engine heat without cracks. I must have to have it tighter to the air box tho you can hear it rattle against the hood when I start the truck.

Perfect fit.

Great product!

It fits 4in aluminum intake pipe. It is very well made and should handle boost just fine.

This product was a direct fit. It worked well for me as I didnt plan to take the intake manifold off for install. Some people have said that this will collapse but I believe that is if your running high boost maps. I plan to run higher boost later on down the line but will make some adjustments to fix the collapsing issue. A few screw clamps around the outside will sure it up nicely. They only need to be snug enough to put pressure on the tube itself. 2-3 of these clamps will do the trick.( BE WARNED you will have to take the manifold off to install it as the clamps will make it lose some of its flexiness overall its a decent product for its price and with a few couple of dollar clamps itll work close to its Perrin and mishimoto 200+ dollar counterparts. Total price including clamps 60 bucks

Is a great product fast shipping.

As described ALL GOOD
