I was looking at cold air intakes. I want all 4" To go with my fast intake and 102 throttle body. The only ones I see posted are home made jobs.
Anyone see anything madrel bent. The closest thing I found was this Products Nasty Performance for all of your late model performance upgrades

 

Airaid has a "u-build it" kit for $119 and its abs plastic..Looks like a good kit also..

 

I just bought a volant kit.....fabbed up the 4" tube from rubber boots and a spectre 4" aluminum tube and plumbed it into my volant box by routing the hole larger and I put a K&N filter with a 4" opening in the box.....sold all the unused parts here.

 

Try the new Airaid MXP 4" series of intakes. A newly installed 4" MXP in my Titan.

 

are you going to use a 4" MAF as well?

But that 4" plastic tubing only has a 3 3/8" inside diameter....
