[Healeys] Spark plugs renewal

[Al Fuller]

OK Steve - I'll bite:  What caused the change from Champion RN12YC to NGK
BP6ES?  

 

Your having kept the Champions in for over 46,000 miles would usually lead
to conclude you had a good to great experience with them.

 

On the other hand, to change brand after all that time and mileage would
seem to indicate just the opposite!

 

Inquiring minds want to know.

Nah.  I usually pull them once a year for inspection (removing for valve
check/adjustment and compression check anyway), clean and re-gap as
necessary, then keep on truckin' until next time.   No reason to do it more
frequently as long as the engine is running well.  I currently have 12,411
miles on a set of NGK BP6ES plugs installed new in October 2012.  I got
46,500 miles out of the previous set of Champion RN12YC.

I see that the BMC manual suggest replacing the plugs every 12,000 miles,
they having been checked every 1,000 miles per the same book.

 

Do you guys hold to that approximately? By that I mean...all things being
equal and the plugs looking OK & working OK, only swap at +/- 12,000 miles. 

 

Maybe plugs last longer these days? Most things don't in my experience.

 

For what it's worth, I'm running NGK's BP6ES. As to the gap, I'll leave that
can of worms closed for the while!

 

Thanks,

Simon
