Spark plugs...

[mallick@orion.crd.ge.com (John Mallick)]

It appears that the my '91 200q 20v may be needing some new plugs to
cure its stuttering problem under boost.  It uses those mucho $$$$
Bosch Platins (number FP60R or something like that), and I was
wondering if regular Bosch W7DTC's can be used in their place w/o
damage.  Given the cost of $25/plug, I can do a heck of a lot of
experimentation with the cheaper plugs for the cost of just one Platin
plug.  

Upsides?  Downsides?  If plug life is the only concern, I have no
qualms about changing plugs every 10-15K vs. whatever for the Platins.
On the other hand, if high boost and compression will eat the regular
plugs in 1000 miles, maybe I'd better spring for the $$$$.

Opinions?
