I posted this thread so everyone can get another look into this airfilter dilemna which is always being tossed around on the forum. I was shocked and surprised about the facts that were listed about the different types of air filters.PHAEDRUS242 said:It never ceases to amaze me the strong emotional response the K&N myth seems to illicit in internet forums. It's like your insulting some one's deepest held religious beliefs when you tell them they have frivolously spent money on a snake oil product. I have yet to see one convincing dyno run showing any benefit on real world street cars. I have however, seen air mass sensor elements coated in filter oil that caused them to fail and thereby cost the foolish owner of said vehicle to have to cough up up to $700 to repair the damage their wonderful little filter caused to their car. I am one of the most "look the other way" service consultants on the planet when it comes to mods on cars. Unfortunately, I am charged for bounced warranty claims, which an oil coated air mass sensor will undoubtedly be, so the decision is made to charge the customer, regardless of their warranty status.
