I was doing some research to order a K&N filter online because here in Per� I�ve been waiting for about three months until a local suplier imports them.......still waiting.

I am absolutely confused about round straight, oval, round tapered air filters; what does it mean?  Which is suitable for my �84 1.9L carburated westy'

Advise please.

TIA

Chau,

Javier
