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

used this to replace the old factory hose on my 2004 6.0l powerstroke. seems better quaity than factory

Fit perfect, great quality

Good hose, keeping my connection from sct maf to anderson pipe no problem.

Great product

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.

great quality product. Very minimal flex when connected to the intake pipe and my bw s366 turbo inlet.

Need a 4 diameter X 3 long connector to connect the 4 Spectre intake for LS3 MAF on Pontiac G8 GT with a Volante CAI. Works great.

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

Perfect fit.

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