Review on PH28041 Extra Guard Passenger Filter by Matt Conner

Revainrating 1 out of 5

Will Robinson danger!

Although recommended for Ferrari 308 engines, this filter does not have a working check valve. This means that oil will flow out of the filter when the engine is not running and when the engine is restarted there will be no oil pressure for a few seconds. Not very good! Not recommended for applications where the filter will be installed upside down (threaded end down).

Pros
  • Oil Filter
Cons
  • Boring Pack
