The blue Honeywell filters are for H4 Subaru engines only. The H6 oil filter OEM is a Tokyo Roki.


Is the H6 Tokyo Roki something that can be used on the H4?

I really can't say for sure. I know it doesn't fit on the H4 Turbo due to clearance issues, but in the past you could put it on the H4 NA. The H6 filter also has the correct pressure relief of 23PSI.

You could call a dealership and find out if it works on the H4. (I think it does, but find out before you do it.)

The Honeywell filter really does a fine job though. Check out this UOA: http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1857613#Post1857613
He uses the same setup as me. OEM air and oil filters with Chevron Supreme 5w30.

I know you already saw this, but this is for others to see:

short answer is no, you don't want to put the H6 filter in the 4 cyl

For those of you looking for the 23 psi bypass filter for a Subaru, follow the thread to the 2009 Mazda RX8 oil filter comments. Should be an exact fit for Subarus, with a higher can capacity (and more filter media?). Filter #N3R114302. My apologies if this info is already in this thread somewhere.

Yeah, that's a good option. The Tokyo Roki's are made very well! Only concern is having the filter close to the exhaust headers... they get *very* hot. However, that's more a theoretical concern than a practical one.

From the spec sheet someone posted on that link, the oil pump's pressure relief setting is 156.6 psi ... Wow! shocked

Look closer ... I said oil pump's pressure relief setting. There is a difference, I'm well aware of that. grin

No problem ... I sometimes do too. wink With the oil pump able to put a maximum pressure of 156.6 PSI on the oiling system before the pumps starts dumping back to the sump, it's no wonder they have some insane GPM spec on their oil system.

The Subaru's oil system is not something that falls in the "norm" of most street cars.

Just when I thought I found an oil filter to stick with, you guys go casting doubt over it smile Been using PureOnes for a while now, even did a UOA over winter and everything came back fine, except for some high lead (45ppm in 4K miles when traditionally it has been around 12). Relief valve on the PureOnes is 14-18PSI, OEM is 20-26. I've had UOAs come back with contaminants in oil on the OEM filters when I used to live out in rural area, that's why I switched.
Insight? I'm inclined to think if it ain't broke don't fix it and continue to use PL14612 especially since it's taller than OEM.
I had contacted Purolator, a product engineer said it's fine and not to worry about it, some people said it may be cause of failed turbos due to the oil line screen filter getting clogged because the filter was in bypass mode for too long/when it should not have been.

That spec is for a Mazda rotary, not a Subaru. The Subaru relief valve is set at 85psi.

Yes, you are correct on the RX-8 spec. That's some pretty high oil pressure. shocked
