go to www.bobistheoilguy.com he has tons of info on filters, oil, etc... The K&N is a highly rated filter, but don't forget about AC Delco. They rated VERY high on his tests, and they aren't even synthetic or anything. I run them on both of my cars, and I noticed an increase in pressure on my buick when I went to Mobil 1 and used the longer AC Delco filter.

I use the oversize Super Tech ST5 which is $1.97 at Wal-Mart.
Most Delco's are now Supertech's...(read my comparo)

The problem with both the Mobil 1 and the PureONE is that in order to get the good filtration numbers they get, they sacrifice some oil flow. This isn't as much of a problem if you don't drive at full throttle too often, but when you do, these filters show a higher pressure drop.

I noticed that problem with the Pure1 filter on my engine too.

Hey, I've been using the AC Delco PF 1218. It's longer than the PF 235 which I've had problems with. I've used the 1218 for about 3 years now with no clearance problems. AC Delco also makes the Gold PF 1218 which is more expensive, about $8 as apposed to the regular blue 1218 for about $3. My .02

I like the AC Delco's 25,but can't get them anymore except through the dealer(was paying about $2.89 each at K-mart.)Now I'm using the Wal-Mart brand,and so far ,no leaks.When I put the two side by side,they look identicle,but maybe someone should cut one in half to see if there is any difference.
Previous problem with Frams that I had is that they leak,no matter how tight I tighten them.(2)
Hope this helps.My understanding is that the engine only filters one third of the oil all the time anyway.I change mine about every 2-3 k ,or three months anyway because I like the look of clean oil.(Freaky huh).My02.

I have always used AC Delco PF 35 or when I could not find a 35, I would get the normal PF25. Recently, I switched over to the 1218 filter from AC delco but I have never had a problem with any AC delco filter (I have been using them for well over 120K miles).
Thx,
Claude
