Toyo Roki no longer makes our PCX filter. It's made by FILTECH now.

Thank you for informing me of that. I was unaware they made the switch to Filtech.

Knowing that I will humbly revoke my recommendation for the OEM filter and will stick with the Hamp.

Thanks for all the info everyone.
I am going to give one a try on this oil change. don't like the price though but it advertises ability to handle a lot of pressure and has a one way valve in it. I like the ability to take a lot of pressure part especially. my car has high mileage and I want to give it strong oil products.

Any comments on my findings also welcome.
Thanks

So does this now invalidate the report RR did on why the OEM filter is our best option? Id be alot more inclined to believe his conclusions... but if something has changed with the filter then id love to know.

If you want longest engine life then OEM-type filters are the way to go. They trap more dirt. But oiled foam filters do have a little better flow. Makes a bigger difference in other applications. I tested some french K&N-style filter on my AP1 years ago (before K&N had one) and got about +2 HP on a dyno, nearly in the noise and maybe just thermal/ECU/temporary fuel trim effect.

If you do go K&N-style make sure not to over-oil the filter when you clean it. I've seen more than a few messed up air-flow/mass sensors from excess oil migrating down the intake from the filter.

This is what K&N says about the advantages of their oil filter's higher flow rate.

"High-Flow Rate
Our oil filters use resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration. High filter flow rates are important in racing vehicles where heavier grade oil is used and the oil is pumped much faster than in a standard vehicle. When the engine is circulating oil at high GPM rates, the high-flow oil filter helps reduce the loss of pressure through the filtering process."

oil filters...read the subject line, please

yes

M1 or K&N are the best filters commonly available, without going to a remote mount set-up

I took alot of flack here for using an M1-104, but the fact is it works very well, after 3,000 miles the oil still looks great (light gold color)

Where do you usually get M1 filters for a good price? The local auto zone carries it, but it's $13 for one.
