The 246 calls for Champion N60Y. This is not to be confused with N6Y. The double-digit Champion plugs are from the racing series and are all a lot colder than the single digit plugs. So N60 is colder than N6. I ran the N6Y for a while before I figured this out but switched over to N60Y and man, it sure seems a lot better. Getting kind of hard to find these but you can always just go with a colder plug from NGK (higher number) or Champion (lower number) in the normal series. |

Steve, Thanks for the info. I'm going to try the BPR6EVX and see how they run. I think it's a slightly hotter plug than the N7YC's that were installed. Joe |

Joe C. -- it's a little more complicated than just NGK vs Champion for what's "best". For "standard" type plugs (large diameter center electrode, non-exotic electrode materials) -- I'd say the NGK (BPR6ES) and the Champion (RN9YC) are equivalent. The "better" NGK plugs are the VX series plugs (small diameter center electrode, exotic electrode materials) -- e.g., NGK BPR6EVX (although pick the heat range number based on your usage). |

10/4 on that. What I was trying to say is that this is what worked best for me in case some one was running a standard system with a little hotter, or Hot Rod coil, as you call it. |

I've got the stock coils. Not as hot as your hot-rodder ones, so not as a big a gap needed. My ignition system primarily controls timing, it only produces slightly more current. |

Peter, On my 308 I had a rich problem that was unbelievable. I don't have a HEI system but I replaced the coils with HV Accel coils 52,000 volts ea. I tried various gaps on my BPR6EVX plugs and .040 gap gave me better starting. no rich smell, and better overall performance. Plugs burn just as you described. |

Joe, I've got the NGK BPR6EVX plugs in my car, set at 0.030" gap with aftermarket electronic ignition and they read fine (sooty thread body, tan/grey coloured insulator and grounding prong).
Using this site's "Keyword Search", type in "spark plugs" and/or "spark plug gaps" and you'll find more than enough information on heat range and driving conditions.
Most agree that the NGK's are a better plug. |

David, Your problem may be that your antenna trimmer is out of adjustment. I would assume that your radio has one which is usually behind one of the radio knobs or some you have to remove the radio and at the antenna plug there is a adjustment screw. Put the radio on the weakest A.M. station and adjust to the clearest signal. Also make sure your your antenna lead connections are good at the radio and the antenna. |

Can anyone recommend the correct plugs to use for 84 GTSi QV? Pulled one out and it was Champion N7YC. They're wearing normally. Owners manual lists N6GY, RN6GY or N6YC. Or should I use NKG.
thanks,

Drew A. -- Unfortunately, there is no "standard" for heat range numbering/order between spark plug manufacturers so just like you noted: lower is hotter for NGK, but lower is colder for Champion. Also, the Champion "6"s are equivalent to the NGK "8"s heat range-wise which are both rather cold plugs -- for normal US street use, I think you're just fine with NGK "6"s (which would be equivalent to a Champion "9"), but I'd still recommend using the NGK BPR6EVX to minimize any fouling (especially if you do a lot of short trips where the plug tip doesn't reach the self-cleaning temperature). I've found this site:
http://www.clubplug.net/cross.html
to be very useful for cross-referencing plugs and they have great prices!:

(I know the service guys need to make a living, but $15 for a VX plug just gets under my skin!) |

There are a few people on this board (I can't remember who) who have used (are using) them with no problems. |

I have the black plug extenders. I thought the red ones wouldn't work in a 308. |

David, do you have black spark-plug extenders? These are non-resistor type and could be releasing alot of RF noise that is probably interfering with the radio. Red spark-plug extenders are resistor type and could help. Just a thought. Good idea to replace these items once-in-a-while too (I personnaly don't like the spring-locking mechanism of these extenders. I always thought that they should have a matching thread for the spark-plug terminal. I guess they chose this method, because if the thread was too loose, it may arc. But still....)
Drew, I remember Steve Magnusson posted here, a great explanation on heat-range choices for types of driving conditions. I was just looking it up recently. Try the "Keyword Search" function on the left-side tool bar (at this site's home page). |

I just traded out my BP6ES plugs for BPR6EVX plugs yesterday. My old plugs were fine, but I couldn't get am radio reception. I thought resister plugs would help and while I was at it, I would upgrade to platinum. I didn't notice any difference in performance and I still can't get am. Your car is older than my '85 308, so you don't have to worry about throwing the fuel/emissions system off balance. You might want to try a slightly hotter "5" plug. |

Regarding NGK plugs. I seem to remember reading the higher the number the hotter the plug. However when I went to the NGK web site it showed the lower the number the hotter the plug.
My 512BB (carbed) calls for Champion N6Y. I am currently using NGK BP6ES. These work pretty well but I notice that if I use the car for a series of short trips I get some hesistation on drive away as time goes on. Its not until I have an opportunity to take it for a longer sustained drive that the condition goes away.
I'm not consuming any oil to speak of and get a little smoke on startup but its gone in 30 seconds.
Anyhow I was wondering about switching to a slightly hotter plug. But if the NGK chart is correct I think I'll just stick with the BP6ES.
By the way, when I look up the plug type for a 512BB on the NGK web site it recommends a BP8ES.
Any help would be appreciated.
