NGK Plugs

[safeguy150]

Anyone using NGK plugs in an 8BA? if so any pros or cons?

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.

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

B6L’s working good with my EAB heads.

Lots of positives! Same plug you'd recommend for a stock 221?

 

[flatjack9]

Yes

 

[Talkwrench]

Work fine on my 21 studder...

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.

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.

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.

Maybe thats why your bolt is falling out

Won't hurt to add a dab of anti seize.

When RONNIE ROADSTER had my 40 this Spring that's what he installed. Runs great.

Why B4L and not B6L?
