I posted earlier about a (dealer) 5 labor charge for changing the spark plugs in my 2001 PT, and for changing the power steering fluid. The shop I've been dealing with for the past 30 some years quotes for the plug change, and for the PS fluid. Why do I need to change the fluid I asked. To flush it, to get metal particles out because of possible damage to the pump and the rack. OK, I'll go with this. My question is...........What plug should I buy to have put in? I believe I read awhile back in this ng that the mpg and performance can be enhanced by installing a particular brand of plug. What brand of plug would that be? Any other suggestions for having something done in this "tune-up" that might improve mpg/performance? And no, not installing a 0+ exhaust system and other changes with a 50 year payback period.
