Hi. I ran the 998 of my stepsister to the imm with no problems what so ever exept 1... when it is running low revs ( idle and just above as for example waiting in a q) it makes the sparkplugs go dead. ( when normal running the sparkplugs are nice and brown when in q or long time idle they get so black that they stop sparking) a normal clean with a wire bruch always solves it. But now i was reading in the Haynes that a 998 should run on bpr 5 es instead of the bpr 6 es that are in there now. Would it make any difference?

you can do anything if you set your mind to it...
i rather blow it up winning than keep it together losing.

No, not really, 6s are what I've always used with no problem.

hmm. must be honest i do not know the afr all i know is that it is running 4.1 co on idle and 3.5 on revs whish is more or less within legal norms for a car of those years ( here in belgium)

Is this purely for the 998s? I run 8s? Always spot on. 6's in my 998 n 1275 n/a

Okey the shop only has the bosch equivalent. .. can't hurt trying right...


The co? Here the grade of co changes with the build year of the car. Or the sparkplugs? If i read correct the 850 ,998 and 1100 should run 5's and 1275 6's

R's have a resistor E's don't, you can fit ford rs turbo plugs (don't know whether there 5 or 6 or 7's) they're a colder plug for boost or hi compression
