Thanks Rob, really appreciate your input. I'd really like to go OEM for the filter but it's like $250 for one here in Australia...dunno why. Cheapest I can find after market is $160 odd dollars for a ryco z626. Apparently Ryco have been making them for a year and a half now. Hope the quality is comparable....

Great to know that it doesn't throw error codes, that's the piece of mind I was hoping for.

Cheers
Josh
