Had a 15min search of Google but could not come up with any advantage for BKR over the BCP which seems to be the standard. Do either of you have a reason to prefer BKR? All I can find is that BKR is made to an ISO standard that means that the bit that sticks out of the block has slightly different length. Not knocking them because I have never tried them but how do you reckon they are better than BCP and how do they compare price wise?

[jarrod83]

i think its because the BKR's are v notched and are meant to produce a bigger spark

bkr6e'11s regap to .8mm 2.60 a plug . cant go wrong

[JonnoHR31]

generally price. like i said 2.60 a plug compared to 3.20 :S

Always check the gap, don't just assume they are 0.8mm because the box says so.

I run BCP's in both my Nissans.

BCPR's the BKR are shorter and can cause arcing between plug top and cop (premature cop failure).
