I need to get a new bypass valve for my intake and I was wondering what size the intake pipe was? I was thinking 2.5? 2.75? I'm not sure though. If anyone can help me out just let me know. Thanks for your help.

 

i think it's 2.75, i know it's not 3.0 for sure ... but i'm not too sure myself.

 

No it's 2.5"--the Accord TB is small. Do you have your original--All bypass valves are the same--they just swap in different spacer rings for the various intake sizes. AEM sent me new foam to rebuild mine after I tore it. If you did this give them a call--I've had great tech-support from AEM surprisingly.

 

yeah, i just put on my bypass valve like a week ago, and the foam already tore, will that mess it up?

 

yes because you're not filtering the air that's entering the TB

 

Just to verify, so it's 2.5"?
