I'm in a bit of a unique position in that '09+ RX-8s have slightly different oil filter specs from the previous generation, and apparently not all aftermarket filters have that in mind. Sticking with OE is my way to preserve peace of mind on that point.
The OEM Mazda filter I bought at the dealer for my son's 2004 RX8 was Champion built.
Recently, I purchased four D3300 Bosch Distance Plus filters for the '04 RX8.
I moved up to a filter with more dirt handling capability due to the filter's very small physical size.
Bosch recognizes the difference in the RX8's because the fitment for the newer car is D3323.
I believe FRAM is a 6607 for all RX8's, no matter the year produced.
The Bosch Distance Plus D3323 could be a good option for you after your warranty expires.
