i use fram with the grip on the end. ph3506. easy to put on and take off by hand...

 

I ve been using the Bosch filter. Relativly cheap an the only other ones they had were frams and k&ns. I wont run a fram and didnt want to spend 15 bucks on a k&n. Most guys on here will recomend the delco's but I havnt had a chance to get one bc the didnt have any in stock...

 

K&N or Mobil 1...NEVER a Fram as I've seen the inside of one cardboard endcaps and all.

 

AC Delco PF-59 for me

 

acdelco they get rid of the "valvetrain" noise associated with other filters also they flow the best ive heard

 

Wix filter

 

AC DELCO PF 59 only for my truck.

 

I have been using Frams, but after reading that study I am considering a switch to AC Delco. I was just wondering, isn't AC Delco a GM company? If I go straight to GM to buy a filter, are they gonna sell me a AC Delco filter, or is it another type?

 

they will sell you an AC Delco filter. All replacment type parts are generally AC Delco.

 

If you go to the dealer (Chevy or GMC) they'll give you AC Delco...last I checked I couldn't find PF-59's at WalMart or K-Mart. I bought 5 of them from GMPartsdirect.com...good price but they nail you on shipping.
