Has anyone tried the K&N Hi Flow Air Filter? What difference if any has it made? Is it a direct swap out? For those Canadians online, any Toronto dealers?

I installed the K&N drop in, it replaces the factory one but the fit was not perfect, you have to squeeze and push and wiggle it in. Otherwise it fit well. Install was 5 mins. I noticed about 1-2 increase in MPG and a bit better throttle response and felt overall better and also you get a bit more sound from the engine compartment with it.

I am staying with the K&N until they make a decent design for a CIA. I don't want one dangling in the air dam collecting dirt and water and I don't want one sucking hot air from the engine compartment either. I think the stock airbox is well designed and a CIA will only have minimal gains over the K&N.
