good link to a guy who took apart all major brands of oil filters to examine what they were made of. Amsoil seems to be the best constructed

 

amsoil seems to be the better one

 

and Fram seems to be the worst

another relevant clip about how sh1tty Fram is

 

I use K&N, I would like to see whats in that

 

I use Napa Gold, which is made by Wix. The Amsoil might be a better filter, but I'd like to see the spec sheets (Beta ratios specifically) rather than a video. It's also twice as much as most filters. Their website says you can run their filter for 25,000 miles or 1 year if you're using their sythetic oil. I only run about half that many miles in a year, and considering it's only about $9 for the very high quality Wix/Napa Gold, I'd rather just change the filter every 5,000 miles when I do my synthetic oil change. I'm under the car already, and I have to remove the filter when draining, so why not put a new one on.

 

K&N uses Champions High Performance filter, Its a great filter. ( I use this filter)

The Nissan OEM is the same as the cheap fram.

I've always used mobile1 filters (and oil). No way a fram has ever or will ever touch my G.
