Review on 🔒 Mann-Filter HU 719/5 X: Top-Performing Metal-Free Oil Filter for Optimal Engine Protection by Darrell Shreves

Installed the filter twice in my Porsche Boxster S. As the engine is in the center of the car and there is no dipstick to actually see the oil in the engine I am only presumably this filter fulfills its task. What I can see is that the filter fits into the housing and the included rubber o-ring is not leaking. More importantly, there isn't a Porsche dealer near me, so I don't have access or money to buy from a dealer. To be honest I change the Porsche engine oil every year and the oil drained from the engine seems clean so this filter seems to be working.
