Upgrading to 4" Cold Air Tube- question on parts
I need something that will allow a 4" tube to transition to the oval throttle body flange. Anyone know where to get something like that? Thanks.

When i made a 3.5" CAI, i just used a 4" to 3.5" piece of silicone coupler. I got it from here

TPI TB is about 4" oval, so the coupler fits over it.

For my high flow air lid, I have 4" OD pipe at the outlet side. I used a length of 4" silicone hose from that to the thottle body and it fits very nicely.
