3.7 throttle body upgrade question - Mazda 6 Forums : Mazda 6 Forum / Mazda Atenza Forum

elemento_74 · 11-24-2012, 09:04 AM

Hey guys
I just finished installing the 3.7 TB on my 6 and i have been thinking;
The TB intake measures about 3" and my CAI piping is 2.75.
Is it possible to upgrade the CAI piping to match the TB bigger intake?
Will that 1/4" really make any difference?
Thanks guys

The only 2 intakes that are 3" are CPE and Injen. The CPE is no longer on the market and the injen will cause you to throw a lean code(not actually running lean).

Lean code from running injen can be fixed using an air straightener from my understanding. Or finding the mafci unit that CPE offered but they are hard to come by.

But will it be worth the difference?
I mean,going from 2.75" to 3",will it be noticeable power wise?

All you will be doing is throwing lean codes, you will not notice any difference without tuning. If you upgrade the piping and run an air straightener, it is just like running smaller piping. Not beneficial at all without tuning.

then you may as well have just run a 2.75" diameter intake. because thats essentially what you are doing by installing an air straightener. reducing intake volume around the MAF

Mr.Smoke · 11-27-2012, 08:29 PM

Ahhh gotcha. Thanks for clearing that up Justin. All i had heard/read was that an air straightener would clear up a CEL for lean code due to intake install. Didnt realize they reduced piping size down & reduced volume.

You will even gain a great amount of power stock, even more with bolt on's as you can maximize the potential of each one working together. I'm getting the Powermod for Christmas so ill let you know the results of a fully bolted up 6 before and after the tuning...def gonna have the dyno sheets as well.
