CAI size question

[shogun99]

So i just got a deal on a Civic CAI but the tubing only measures 2.5 inches across. What's the diameter of the usual intake. I was hoping for at least 3 inch tubing. I talked to the guy at my performance shop and he said that im gunna LOSE power if i stick with the 2.5 inch tubing. What do you guys think? He alos said that i should replace the plastic acordian tubing between the MAF and throttle body since the acordian ripples affect air flow. Al that money wasted looks like! :rage:


thanks

The same thing happened to me. I bought a tube off Ebay without knowing the diameter...duh!! It was 2.5". The MAF on our cars has a diameter very close to 3". I was able to re-sell it for the same price. So i made even.

I just bought the civic intake tube and was also suprised that it wasnt as wide as i thoguht it would be. I installed it and also made a piece to take the place of the rubber section. I got an slp exhaust from APOC and had john ship me a rubber CAI copler with the breather and iat sensor gromets. And got the rest at home depot and autozone for the steel pipe.

Love the CAI sound!:thumbs:

so you are running a 2.5 inch civic intake from the MAF down?
did you see a significant difference in power? cause im told you actually lose power cause the intake is built for a 4 cylinder honda and doesnt feed enough air for out 3.4L V6.

It doesn't make a huge difference when you aren't running a lot of mods.

APoC is 3" I believe, almost positive...so it would be better in the long run if you plan to do lots of mods and push some power through it.
