Re: oil filters (biger vs smaller)
We used to use a very small filter on our race Clevo, from memory it was from a 3 series BMW, which happen to be the same flange size as a Z9.
4L I6, naturally aspirated producing 173.5rwkw.
14.410 @ 96.49mph with street radials.
What's that?..... Did I hear you say TQE power?
