I have the Bales adapter installed for the last 27,000Km. I'm using Mobil1 M1-110 filters because they are available in my local store but any of the following will be great. They are all 3.25" long, so i suppose they have better filtering capacity than the OEM 2.5":
Purolator Pure One PL14610
Mobil 1 M1-110
Bosch 3323
WalMart SuperTech ST7317,
Wix 1356
Most are made by the same manufacturer anyway (Champion).
Not much else to tell. The adapter was very reasonably priced, installation was relatively easy, Mr. Bales was a pleasure to do business with. I've had no issues whatsoever since the installation.
