About to do a tune up and the p.o., good guy that he was , left me some new spark plugs: NKG BP6HS (note not the: BP6ES*) You may have read that the BP6ES are the ones to run.... and you think there would be a tech article about it... but I can't seem to find the answer for a stock 1.7 the plugs in there now are Bosch WR7CC gap seems to be .030 That the proper gap?..... I could probably look that one up.
Might as well change the wires, too, if someone knows a good source for those.
Thanks.
* fourth letter has to do with thread length , I think.

I get my tune up parts at FLAPS.

You don't necessarily want to go to a local FLAPS in the greater NYC area. It's surprising what they get wrong.. But its worth a try.
W7CC is a fine plug for a stock 914. Not sure about the resistor one, though. (That's the "R" in WR7CC.) BP6ES works well too.

I typically install Bosch WR8DC+ on customer cars unless they specify a certain plug they desire. Either of these have a slightly extended electrode (the "D" in the p/n) and they seem to have less fouling issues for me.
NGK B5ES....equivalent of the Bosch W8CC
NGK is by far a better plug these days.
