I normally use Mahle-Knecht or Hengst Oil Filters since that's what most local parts shops carry. The other day I was sold a Mann W719/5 for my '91 300-SEL. I seemed to recall having seen a different Mann part # for my car.
Got on the WEB and did some digging. Sure enough, the M103 motors use Mann Oil Filter W719/13; not W715/5. What's interesting is that the Mann W717/5, W719/13; W719/15 are identical in length and O. D. I suppose the difference has to do with bypass valves/check valves, etc. What affect would it have to run a Mann W719/5 or W719/15 on an M103 motor vs. the prescribed W719/13? I have no intention of doing so. I'm simply curious about the internal differences. Thanks for your time.

The W719/13 is a MB OE quality filter with correct burst pressure & anti-drain back valve. The W719/5 is a VW filter & doesn't come close to having the correct check valve! The W719/15 is a BMW filter & has different check valve also. MB requires the W719/13 due to fact it's upside down.
