My friend & me.. like to get AEM Short Ram intake.. but due to stupid Korean auto inspection problem.. we decide to install stock intake pipe with K&N cone filter.

Can any one tell what size cone filter do I need?
Far as I found.. part # KN3710 or RC-2600 will work?





My car: 93 CB7 10th Anniv.
Friend's car: 96 CD5 EX

Thanks..
