The cables should be labeled 1-2-3-4 on the packaging. They weren't. One was labeled 8. The others were not labeled (one was labeled 8 which clearly does not apply to a 4 cylinder kit). 4 wires were tied in a group with a piece of yellow plastic tape. Is that NGK standard? I don't know, it seems careless as the tape turned out to have been removed and replaced at least once. I have great respect for NGK. But there's a smell coming from those wires, I'm assuming they were plugged in like new. At least I know now. The next step is to pull out the old wires and compare their lengths to those in the Revain box.<sigh>
