I've digged through AZ and internet and haven't found answers.
Im wondering about buying AEM intake. I live in EU so it's little more $$$ them on your site and no sending back option, so I want to make right decision.
There is AEM V1 21-513x (Acura TL) and AEM V2 24-6110C (Honda Accord).
1. what size the tube is. The 3,25 and 3 inches as I've seen somewhere?
2. Have any one Dyno it? As somebody suggested somewhere.
3. I'm also thinking about 3.7 TB and IM. Does it make a difference which one I go? If 21-513 is bigger and 3,25 it would be the same as 3.7 TB.

 

Any information?

Here a a few threads, if you have already been through them than you may have to look on other forums, like for the Accord?

Ok. I've found the information about tube size on air inlet side.

AEM 21-513P (Acura dedicated)


AEM 24-6110C (Accord dedicated)

I asked AEM customer service about the tubes outlet dimensions, however they didn't answer directly - they said both TB are 3 inch.
