Spark Plug for M21

[Lembit]

What is the correct NGK or Champion spark plug type for the '63 M21

I have seen references to A.14.Y and A14U, but does anyone have the correct NGK or Champion type

thank you

Hi!

I can not find any Russian or Soviet plugs A14 using the letter "U" (or "У" in Russian). A cross-reference can be found here: http://forum.gaz21.org.ua/index.php?showtopic=177&mode=threaded .

The original type is A8NT (А8НТ in Russian), but I have found some information abuot A11 too - could be the difference due to the changes they made in the numeration system. That means NGK B4H or Champion L86C. The A14 series would be for the later GAZ engines: http://avtodelo.net/default.php?rubrica=6 .


Happy hunting!
