I thought WJM went over this a few months ago? The blue filters are made by Honeywell (Fram) and the black filters are made by Tokyo Roki or whoever that JDM company is that use to make all Subaru Filters. I think he stated NOT to use the blue filters. I have been using the black filters from a H6 on my car without any clearence issues or leaks.
he did but the pics are gone. Besides...that thread was junked up with Bug-Rex trying to figure out if he could "swap filters w/o loosing oil." http://www.wrxatlanta.com/forums/showthread.php?t=22456
Damn! I recently bought a 6 pack of the blue filters from SOG. But they told me that was the new replacement and the black filter was no longer available.
The fliters for the H6 motors are still the black ones and I haven't had any problems with using them on my 2.5 motor. Matter a fact, WJM was the one that first tested it to make sure it would fit.
SoK has them in stock. I just bought one a couple weeks ago. They arent in a box anymore...just shrink wrapped
I got a blue one last time I bought one from SOK and I think I have always gotten the blues on the GR.....:unamused: I will for sure ask for the H6 AA031 next time...
I am glad I have a couple left from when I bought them. Subaru Genuine Parts may still have some online as well.
