The sparkplugs for
a (3B en ABY) S2, are a strange story. Some carshops have a NGK spark
listed in their computer for the S2. The only right spark plug are the
Bosch Platin F5DPOR. Not to be confused with the cheaper Bosch Platinum
spark plugs which have a thinner electrode. The Bosch FR5 DTC plugs are
also being found in the S2, these plugs also don't match the specs. For
example. the have a cupper core instead of platinum. Ask for the right
plugs with your car maintenance.
Turn the plugs stuck
in your engine. Don't overtightened them. Feel the compression ring click
when you turn them in you S2. New plugs must be tightened with ±22
lb/ft or 30 Nm. Used plugs must be tightened a little more. Put some cuppergrease
on the plugs to make the turning more easy. Check the plugs torque now
and than, especially when you are running higher boost.
