What's the best air filter for a 2011 Jeep wrangler? It's my ol lady's. She stays pretty much in town with it. and how often should it be changed? Thanks.
Here is a pic of my S2000 with gauge
That gaude tells you when to change the air filter out, you want to get your money out of the filter you buy but you don't want to run the filter when its cloged up and this gauge tells you when that is happening.
