Can someone help me find a 2.5 inch to 4 inch coupler for an air intake.

 

I had a 3" -> 4" that I got from silicone intakes and TBH if I had to pick one up again I'd be looking elsewhere. I just didn't think it was very good quality. . . I've purchased other siliconeintakes stuff and felt comfortable using it on the intake side, just not this coupler.

Good luck finding a 2.5 -> 4". . Just sounds like it's going to be hard to find.

 

I got a ITG filter that has a smaller waist, buy it.

 

i got one from 4" to 3" let me know if you want it

 

Vibrant should have them if not look on ebay they are all over there
