Getting ready to go on a short trip ,had about 4K on the oil so i just changed my oil and came across a k&n oil filter, was comparing it to the fram i had PH3976A and noticed that the fram has 6 3/8" holes on top while the K&n filter has 8 which 7 or about 1/4" or so and 1 was a little bit larger also the inner screen looked somewhat like a cheese grader. guess i will find out how my truck does cause it is on the truck now. Just wondering if anyone has used them a bit pricey? OH the filter was K&N perf.gold HP-4003. Thanks

 

I ran one for years had no problem, just keep up on your cleaning it and it will last for ever you will hear you turbo thur it, save your pennys and get the afe, thats i got the afe stage 2 and love it

 

I think he's talking about a K&N OIL filter

 

ha ha yeah look at me sorry never have used one

 

The only oil filter I would trust is FLEETGUARD. (Cummins made filter)

 

Me too..Fleetguard Stratapore (LF-3849) is the only filter that ever touches my baby.

Heard some horror stories about K&N oil filters.

 

Most people buy a K&N because it got that 1" nut welded on the bottom... Big deal...

So far every oil change I never hand to use a oil filter wrench or other tool to remove my filter. I can twist it off by hand every time. thread the filter till it makes contact. On the rear side of the filter make a scratch mark or similar. Now twits it 3/4 of a turn the mark will face the passenger side! Your done...

 

I 3rd that, when I bought my truck I bought 8 fleetguard filters from
genos.

 

I usually use Fleetguard or Fram

 

A mechanic buddy of mine has rebuilt 2 Cummins engines that had K&N oil filters on them.
