Re: NGK Plugs
I'm using NGK's in my blown flathead with excellent results. They were recommended by some well known people here and so far so good. My 2 cents.

Re: NGK Plugs
Me too. B6L in an 8BA style Merc slightly "warmed up". Plugs look just right. Milled 8CM iron heads.

Re: NGK Plugs
Lots of positives! Same plug you'd recommend for a stock 221?

Re: NGK Plugs
NGK's are one of the only plugs where the electrode is indexed to the threads, if that means anything... I like 'em.

I use the NGK GR4 2635 plugs recommended by Mark Kirby when I bought his heads in 1999.
Work fine. |

Re: NGK Plugs
Thanks guys! I am learning the value of a well tuned ignition system from the slot in the end of the cam to the tip of the spark plugs.

Re: NGK Plugs
The gold color on the threads is something sprayed on to help keep the plugs from sticking to the head so you can never strip the threads when removing the plugs. They break loose easier that way.
I just started using NGK plugs in 1972. I installed NGK plugs in my F1 in 2006 and again in 2016. |

GB, B-4L is a hotter plug. Probably a number of reasons to use a hotter plug. I've used them in engines that used oil and they ran better and burned cleaner than with a colder plug. Otherwise, I use B6L. Ken |

Re: NGK Plugs
I overhauled mine about 3000 miles ago , 120# compression, uses no oil I guess I'll buy the 6!

Re: NGK Plugs
What Gap is used on the B6L NGK plugs?
Do these plugs burn hotter that a 216 Autolight? |

The B6L is equivalent in heat range and operation wise to the 216 and the Champion H-10 The difference in the NGK is they will perform much better compared to the other two. At least thats what I experience when comparing the three in equal / identical applications. For gap .035 Ronnieroadster

Re: NGK Plugs
OK, I am always questioning. So for my stock, but 12v 221 I want to set my plug gaps to .035? Hoping to pick them up on Saturday if the smoke clears up enough to find the Napa store.

Re: NGK Plugs
Personally I wouldn't use a gap as big as .035. The HT side of the ignition can be a weak point and the spark will try and go anywhere except across that plug gap. It takes a lot more energy to jump a 35 thou gap than a 25 thou gap.
I have always used the autolite 216s. They work ok for me. I will probably try some NGKs next time, but I can't see how they will be better. As long as they work ok they will be as good as the 216s. You need to have a plug type that is giving problems to then state that the replacements are an improvement. NGK are a quality brand though and are an OEM supplier to the automotive industry. Mart. |

Re: NGK Plugs
Not 100% certain but I was always under assumption that plug gap for points is different from electronic ignition around .010” smaller? .030” points .040” electronic. Depending on the system? And magnetos even smaller? Say .025”? Just asking ��

Re: NGK Plugs
I switched to H10’s because I had three electrodes pull out of the 216’s. Never thought to use NGK, but I’ll give them a try next time I swap plugs....... Mark

Mart the plug gap at .035 if its a 6 volt system or 12 volt would only be the weak point of the HT side of the ignition circuit if the plug wires being used are junk. Since many of us have had problems with both the 216 and the H-10 stating the NGK replacements are an improvement is exactly what we are doing. Ronnieroadster

Re: NGK Plugs
As for me it was the crappy plug wires. I learned a lesson about path of least resistance, and now I want the best HT side I can conjure up. Best plugs, best gap etc,.

Re: NGK Plugs
I gap at .025. Years ago I used a wider gap. Have a crab distributor and would have problems with carbon tracking in the cap. Probably poor cap quality. Tried several different brands, same thing. Dropped to .025 and have never had a problem since.

Re: NGK Plugs
As the gap is increased the energy that the coil outputs increases. At some point the coil output can exceed the insolating properties of the system. Because the of compression, most flatheads do not require that much spark energy.

When I put the NGk plugs in my 51 EAB stock engine, they ran very well for a few miles. Now I am getting a "fuzzy" carbon build up on the plugs causing power loss. What gap are you all using? What else would you suggest I check out? Thanks in advance for the help. |
