Negative Positive
Title: Danger Will Robinson!
Review: Although this filter was recommended for Ferrari 308 engines, it does not have a functioning check valve. This means that the oil flows out of the filter when the engine is not running and when you re-start the engine it will have no oil pressure for a few seconds. Not a good thing! Not recommended for any application where the filter is installed upside down (with the threaded end facing down).
