  1. I assume for the AVCS oil feed lines, the factory style screens are not used right? I only thought about that because the style of banjo fittings used have the bump on top, which for Subaru means they put a filter in there.
    I’ve always wondered how dirty the inside of the cam covers get over time.

  2. When do we finally get to see this bad boy on the dyno? What intake, what turbo, what exhaust, what blow off valve, what header? This is 5 months old!
