Anyone given these a try or know anything about them? Are they worth the extra couple dollars? Thanks.

 

these are the only oil filters i use, i trust KNN no other reason that i use them though

 

i've used them before, now i just use stock mazda ones

 

i remember a post a while ago giving some specs about the filter and apperently it was pretty good. however, most say that nothing beats mazda oem. i use the pure-one filter, but only because the nearest mazda dealer is 30 miles away and i dont feel like driving out to it whenever i do an oil change.

 

meh.... no difference!

 

I use the K&N oil filters. As far as I can tell, they work pretty good. My oil is still pretty clean when I do my changes at 2500 miles! Thats the only filter I have ever put on the 7.
