Thread: Re-doing CAI

So I made the mistake of, when buying tubing for my CAI, buying 3" tubing, and a 3" filter. If I were to go out and buy some 4" tubing, would it be just as good to use my 4" to 3" coupler to attach the filter to the 4" tubing? Would that yield as good, or almost as good and a 4" filter?

I'd hate to have wasted $30 on a 3" filter -_-'

Yes, that will work fine.

Well I pretty much tried the same as you a few days ago and I'm also pretty sure that most people will tell you that you're better of with a 4" tube and filter. Check out this thread in I went through the same thing:

I took some videos of the final version and you can see them here:

He is switching to 4" tubing. It will work fine

kk, I might do that real quick here, but I'd love to know what Bio and Blue think

You would say that =P
