Hey Guys,

So I want to go ahead and change my air filter on my hahn intake... but I cant remember what size I need. Does anyone know what size of filter I should go with? 3 inch? 3.5 inch? Also what brand do you recommend?

Thanks.

 

Mine came with a 3" K&N Lifetime Cone IIRC, just buy the cleaning & reoil kit for it for like $10 at Auto Bone.

 

How often should I be oiling my filter?

 

Once a season should be sufficient.

 

I cleaned mine after Winter and about 15k miles on it, it wasn't that dirty yet.
