Spectre Performance SPE-9751 Black 4" Air Duct Hose

Used for the factory cold air intake on my '88 K5 Blazer. The oem hose is discontinued. Put this one in place of the old tube that was crumbling away. Easy to install and worked perfectly. Will order another one for my '85 Chevy K10. The ends just screw on and your good to go.

It fit very good.

High quality flex tubing. NOT dryer hose or remotely similar to it as a reviewer stated. Ends are a bit difficult to thread on the hose but once correctly installed provide a sealed connection. Add hose clamps to fasten it to your intake and whatever you are pulling air from and you are done. The strength of this product is quite apparent. You can form an S with the hose and it will retain its form while you hold it up. This hose was 41" stretched out before I divided it. I needed 2 hoses so I cut this into two and bought an extra set of couplers. Nice and worth the cost to me.

ok air duct hose rubber ends not so much video really lame I put a 3.5 coupler inside hose to make it more sturdy where you clamp it, other wise it will just collapse.

I never understood why the air intake for my P30-based motorhome was where it is, directly over the radiator and blocked by the "hood." Really strange design. Banks sells a fancy CAI for it, but it's expensive and a little awkward, and a tough sell from a price:performance perspective. But the factory setup was really getting on my nerves, and I just didn't want to commit the dollars to the Banks solution. Enter $30 Spectre duct, $13 Spectre aluminum pipe, $3 Autozone hose clamps, and a $10 brake cooling duct intake. Sorted. Now Ye Olde 454 is breathing clean, fresh air, and not second hand battery & radiator air. Some NOS stickers and this baby will be SET!

Perfect fit for my 2004 Silverado 2500HD Duramax with a larger turbo inlet.

This was made of quality materials, but it measured at 3.75" outside diameter, which is far too small to be used for a 4" throttle body.

very nice
