Your Mercedes
A Class W169 180 cdti
I have just bought my first Mercedes (1998 E-class 240 elegance) a close friend has given me some NGK plugs marked PFR6G-11. I checked via NGK website and see that they recommend PFR5G-11.Can any one tell me if the 6 will be ok to use.
Thanks in advance
The Big fella

every plug number stands for heat range etc, i wouldnt use them if the part number dont match your car, you could end up melting a piston!
