man, my exp. with jiffy was the first and only. i then had a very busy schedule and didnt have time to go buy all the stuff and do it at home, (even though ive done it a dozen times before that), so i took it to these jokers. well to start, when i got in my truck and buckled up, i noticed my wipers were missing. they told me they took them off because they were bad, but didnt have the right one to replace so they just put the old ones in the bed.. WTF!? that sparked my interest in the quality of the rest of my work, so i got out and popped the hood... noticed one of my bolts that holds the air box shut was replaced with a zip tie, called the head dee-dee-dee over, "oh yeah, well the bolt was stripped" i reply "gimmie some cutters, i want to look inside" sure enough, my K&N was replaced with a paper filter, i promptly checked the trash cans, i was able to retrieve it. i specifically told them not to touch my fuc**n filter but they insisted (yes the sticker was on the box!), that was the end of them, i havnt let anyone else touch my ranger except for the smog guy...
