Oil Filter Magnets
OK, what do people think about these, especially all you mechanical engineers and hardcore DIYers? Sounds like Boxster owners would largely be limited to the 'slap-on' FilterMag product over the MagDog, since the latter seems to create clearance problems in our cars. (This assumes most people don't want to resort to using the smaller filters available, which allows the use of the MagDog but necessitates more frequent filter changes.)
Pros and cons (if any) to using such products??
