I use K and N it works like a charm

Allright, I'm gonna bump this to the top and add this very interesting oil filter study. I know it has been posted before, but I really don't care if your only goal in life is to waste a post saying "repost".

Go to the bottom and check out his oil filter overview link.

i use the pure one filter from the FC. i think the filter number is 14459. its actually the same filter used on v6 honda accords so there isn't ever a shortage at advance auto or pep boys.

I use the Mazda #JEYO 14 302 9A


Tri-Point put it on my car when they rebuilt my motor. I think it's off the 626.

I just got my RX-7 and am using K&N stock size filters, but also i have 2 Probe GTs (same as MX-6 LS) and im running a ZL1 Oil Filters there rediculously large. when i installed it i noticed a rise in oil pressure so not too sure what ur talking about with bigger filter = less pressure? has anyone tried this filter on a 7? (M1-207)

When I used a non-OEM filter (which didn't have the anti-drainback valve), my oil pressure was MUCH higher. Since that one time, I've always use the stock OEM filter.

That sucks. Fram is terrible. I am curious to know if any racing teams, rotary shops, or rebuilders use the bigger filters or stock size filters.

Sorry, just realized it was the same study referred to in an earlier post!
