Getting a WAI
 

So i'm saving up for a WAI (yea yea after all i've said i decided to go for it).

I just wanted to know about the size/model of a k&n filter that i need to get and how large should the pipe be? and from what material should it be made of?

Thanx a lot!

Usually intakes are 3 inches ID.

You have a lot of choices in K&N cone filters since mostly all of them have a 3 inch flange.

The one I bought for my intake is this model number : RU-2430
