Replacement Air Filter
I just bought my 03 7.3L and want to replace the air filter. It's in okay shape but I want to put an aftermarket one in there. I like what I've seen about the K&N, AFE and S&B. Which one is the best filter to use (my truck is bone stock)? Are any of these 3 worthwhile (I've had K&N before) or is there a better one out there?
Any help is appreciated. Thanks.
By the way I'm just looking for a better filter with more airflow (plus some more mpg's wouldn't hurt either). Better performance goes with it (however marginal it might be) but I just want the engine to breathe better.
