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.

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

Perfect fit.

Fit perfect, great quality

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

Product was delivered quickly and the description and photo matched the item sent. It worked perfectly to connect to the LBZ turbo mouthpiece and cold air intake tube.

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

Great product

As described ALL GOOD

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.
