See the Air Pump Filter here:

What is the inlet size of this type of filter? I want to see if I can get one locally an for less money.

 

anyone?

 

Just pull the rubber hose off and measure the inlet into the airpump(Probably about an inch) and you should be able to find one that will fit or need very little modification at any auoto parts store.

 

It's a 7/8"I.D. female filter you want.
Bigger than those commonly found at Pep Boys and the like (since Hondas use a smaller size), your options are semi-limited.

You can get it direct from K&N (maybe not the cheapest option).

 

Thanks!
