Just beware when using a wrench to tighten it, when it wants to stop turning then you're done. Over time, due to heat cycles, the composite can become brittle and over tightening can break it. It's not a compression seal like the HEMI oil filter, it's got an O-ring and just needs to be tightened enough for the flange on the cap to be snug against the filter housing.
Not a chance. Been doing this for years, although not quite like this. Some engineer(s) finally grew a brain and managed to get the idea across to the management suits and bean counters. Certainly eliminates the spill mess factor.
