So my local shop has paper and metal K and N oil filters the paper are just like stock so no questions there. What do you guys know about or think of the metal ones? I used them in my 04 which now needs a topend, not sure it was the filter though. I am trying to be extra careful with my new 08 so any input would be a big help. I am going to get a Scotts this spring for sure just need something to good to use til then.
