Stock intake arm doesnt fit the new 66mm TB. I bought an AEM Short Ram CAI but that doesn't fit either. I've tried looking around but cant find any information on what i should do, anyone got suggestions?
EDIT: 1999 Honda Civic EX Coupe with D16y8

 

bump, i ordered a 2.75in to 2.25in silicone reducer to fit the smaller 56mm CAI onto my 66mm TB. Will this bottleneck my throttlebody?

 

Not ideal, but not a lot you can do about it. Really shouldn't make a difference though since you're most likely getting more than enough air volume through you intake tube.

FWIW, I'm running a 2.5" pipe that I got off of Amazon for <$35.Same as the Spectre/etc branded parts that you can get at Autozone or wherever but in a wrinkle black finish. I cut some length off the filter end and got another coupler to mate it up to my Comptech Icebox then wrapped it in gold reflective tape. Works and fits fine. I would rather have retained the nice stockish ITR tube that I had on there but there was no hope of stretching it over the Skunk2 TB.

 

Thanks for your reply.

Ya I measured the aem intake tubing and it is like 2.48 inches outside diameter and the skunk2 alpha 66mm tb was like 2.98 inches outside diameter.


Anyone in my circumstance get a 3 inch to 2.5 inch silicone reducer and it should fit(I'll find out on Friday when it gets here). Just got the 2.75 inch to 2.25 inch reducer in today and it didnt fit because I didnt measure it before buying, like an idiot.

 

What size S2 throttle body? I'm using an ITR tube on my 70mm

 

I don't remember off the top of my head how much bigger it was but it was a no go. Throttle body is an Alpha 66mm. Were you able to stretch the tube? I wasn't.

 

Yea, I stretched the tube over my TB. 70mm alpha

 

Ummmm... the 800 lb. Gorilla in the room is: "OP, why did you feel it was necessary to put a 66mm T/B on a naturally aspirated single-jingle ???"

 

^ Lol.

But yeah, maybe my intake tube is too old and dry, maybe I could have gotten it on there with some persuasion... but I wasn’t comfortable with stretching it anymore than I tried to go.
