Picked up some new plugs today and was wondering if anyone knows if these two plugs are different:
Bosch F7LDCR (saw them recommended in this forum)
Bosch FR7LDC+ (the ones I bought today)
One of the boxes says 'SUPER PLUS' on it and shows a diagram of an 'Yttrium-Electrode'. The other three only say SUPER on the box but all four plugs are identical.
From what I've read here and on other sites these plugs were developed specifically for the m42, so I thought it might be worth asking.
TIA
Paul
ps--also picked up some STI wires w/ loom (# 432)
edit: after some more searching I'm guessing that FR7LDC+ replaced F7LDCR(?).
