Works and looks great!
Used this on my 1962 Corvette resotomod for the fresh air intake. Easy to install and looks great!

High quality hose and exactly what I needed.
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.

Easy install. Far better cost option than molded tunes.
Fit perfectly, easy to shape and install. As a bonus it sounds good. Far better cost option than the molded intake tube. While yes the molded look far better but the crazy extra cost for me wasn't worth it. I simply wanted to loose the bulky factory intake. I left my stock air box as it is essentially a closed cold air intake anyways. Very pleased.

Worked perfect on my old Chevy
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.

Excellent beads of intake pipe just missing the clamps
Great 4-in intake pipe it's flexible and the ends are nice pieces of rubber they fit great only thing missing are the two 4-in clamps if that was included this would make it perfect.

Works okay for the price
I used this intake for about a year. It works okay however the tubing wall is somewhat thin and the corrugated texture is not ideal for airflow. What bothered me the most however is the inability to create a good positive seal at the ends. I ended up spending a lot more for a thicker tubing with smooth inner wall which helps airflow and allows me to make a perfect seal with the metal couplers.

Exactly what I needed!
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!
