im just talking drop in filters those ones that replace the tube are a waste of money. the drop ins i put in every car and truck i have had and if you dont go crazy with the oil its fine, i have put 300k on some of my drivers and the only time i replaced a maf was in my firebird before i found out you cant get them wet, i ran tubes out of the box to go were there was more cold air and the first time it rained it went out. which is were people get in trouble . and they only read the air going by them doesnt matter how much, if its more it reads more, thats its job.
