How does it add an extra oil leak? The plate still needs to seal to the block and the filter still needs to seal to the plate.
I don’t see a place for an extra leak.
What I do know for sure is that no decent header will even have clearance for short filter. And I don’t know what is worse. The short filter, the plate or both together.
Last time I looked at it, a plate and a short filter was a 12 or so PSI loss. That’s huge. And it’s not good either.
