Title: filter cleaning
Review: just cleaned my afe filter with afe 90-50000 air filter recharge kit- its a good cleaning kit with the cleaner and oil- i guess you could use simple green to clean the filter, but the oil is a must , because it has no ill effects on the sensors that could harm them like other oils- use it with confidence, its a great product .bought at amazon site, with free shipping making it more reasonable than going to a parts store-
