Hi peeps,

 

I've just received new NGK Laser Platinum sparkies which I ordered from Road Runner Autosport. when they arrived I noticed that the code was PFR6N-11 (stock number 3546) Are these for the 300? I am reading through the zillions of threads and everyone keeps saying about PRF6B-11C? Have I been sent the wrong ones? Any enlightenment would be greatly appreciated before I start putting them in.

PFR6B-11C are the only ones I will fit.... The only difference I can find with the ones you have is that they are a projected tip design - this could lead to detonation since there is a longer path for heat to be disipated into the head. The heat rating may also be wrong but I couldn't find any info on that....

Thanks Andy. I spoke to NGK themsleves and they said it was a spark plug for a Caterham 1.8!! Iwent back to Road Runner who realised there was an error on their website and they are going to swap them over for me. Thanks for the advice though. Ian.

Yeah its fitted in the Rover VVT engine from what I could make out....

Yeah itrs the Rover K series 1.8 in the Caterham. Good engine.......
