are there any benefits to putting a K&N drop in filter instead of the standard nissan or an aftermarket substuite (say from or whatever)? any bad things about these K&N filters? Was thinking about an cold air intake but don't want to have to be replacing my MAF at 400 bucks a pop. are there any intakes (CAI or "pop charger" kind) that don't harm, or at least arn't as bad to MAF's? thanks a lot. this filter is for a 2k1 max SE
