Celica Forums General Discussion Exterior Aftermarket Intake System designs

I haven't done CAI or WAI in my Celica GTS yet, but looking for the best one. I don't want to buy a system and latter find out another one is better, and then have to sell it.

I've read so much on how the MAF or MAS? needs a 2.5" section pipe in order for it to read properly. I heard people have bogging problems with most of the systems out there. How bad is this bog?

I know TRD has a CAI for the Matrix which has the same engine we have, are they using a 2.5" section for the MAF to bolt-on to in that?

So what is the best most proper intake system to get for the GTS?

TPR - but theres gonna be a long wait
