New OEM Oil Filter Part Number?

gojackets · 11-14-2010, 01:14 PM

I've bought OEM oil filters for my 2005 from several different dealers, and have always gotten part number B6Y1-14-302-9A when I asked.

I just was ordering some things from Rosenthal up in DC, and saw that they don't carry that part number any more, now they carry B6Y2-14-302-P1.

They note that it's a "new" filter, and requires a different wrench size, which suggests the dimensions are somewhat different, not just a part number change.

I've searched, but can't find any info on this new part number, and this is not the new filter for the Series 2, N3R1-14-302, which I think is a completely different filter with different bypass pressure.

Anyone have any information on these, or have gotten them from a local dealer?

Thanks!

Yea no reason that I am aware of to have to buy a mazda filter for a s1. I wish I was as lucky as you with that I hate having to drive up to the dealer to get filters. >.>

I was searching for this too, but this thread was all I could find. I went to buy an oil filter today and...

Behold! Doesn't look like the filter we are used to does it? They must have changed suppliers. New unit has a flat o-ring instead of the round one, but I can't tell much more than that.

The OEM filter contains an anti-drainback valve. Although some aftermarket filters have this as well, there are many that don't. Namely, Fram and Penzoil.

B6Y1-14-302A is still valid and you can still get this filter thru Mazda

Other than the Mazda filter being better than the majority of aftermarket filters.

There's a member here who was very knowledgable about filters, and sliced open every one he got his hands on. His posts were a few years back, and I did not bookmark them. But the conclusion was that a handful of the premium aftermarket filters were about as good, but most aftermarket did not even come close.
