Airaid AIR-100-400 UBI (U-Build-It) Intake Kit

Good quality. Thick enough to hopefully stang up to the engine bay heat.

If you're dropping an LS into anything, this is what you want to build a custom cold air intake. It does not soak up heat. It does not corrode. It's very easy material to work with. I've bought several of this 4" pipe.

I used this for custom intake on my jeep srt8, was perfect. Would buy again.

Incredible expense for 4 inch plastic tube but the design is perfect for building your own cold air intake. This was ideal for my project. All I needed was this for all the pipe

Worked awesome for my ls swap in my s13 240sx. Great quality. Can easily build 2 intake systems out of one kit.

I have a 2006 Acura TL and upgraded the intake manifold from a 3.7l zdx and throttle body. Came across a couple of diy's and decided this was the intake pipe isn't wanted. There is enough material left over for me to make a different set up. I wish I could have just bought the piece i needed. It was a very snugly fit for a 4in pipe and did notice after a 30 minute drive, the pipe is cooler compared to a aluminum pipe. Ending up spending about $170 with airaid, 4x7 in aem filter, and coupler.

received the air intake and got sent the wrong one by mistake. contacted the seller and they made it right.Fits perfect and works great! not to mention the great customer service.

Easy to use just cut it and clamp it together. Looks pretty good to me

This is the only thing I have found that is the correct size for a 4 inch intake system. It is badly overpriced in my opinion, but works great. I am still giving it 5 stars because it actually works.

Only needed a straight section if worked as I needed just have a lot of extra tubing wish you guy buy individual sections but worked exactly how I needs it to
