Sparkplugs dilemma

[TheMarsVolta]

Ok so I'm rather confused atm my car is an Euro 525i which is fitted with the M30B25, the haynes manual and the service history tells me I need Bosch WR8D+. The BMW manual tells me I need W8DC plugs in there. What should I go for? I went round all local motor factors and none of them stock WR8D+ but one of them has WR8DC+ I have no idea if these are ok.

At the moment the car currently has the NGK alternative ones, I have no idea if it would be ok to replace it with thoes or would I be good to keep it Bosche?

I'd use the W8DC. Thats what BMW lists in thier parts catalog. Either way I dont think its going to make a colossal difference. No worries.

The R in WR8DC stands for resistor which you have in the plug wires. But bosch does not make the W8DC anymore only the resistor plug WR8DC.
