Listers;
I have a 1954 Sunbeam Alpine that I run NGK plugs in.
Why ??, well I have 35 years experience in the motorcycle business and have
tried every common spark plug there is.
When you are dealing with a single cylinder engine, any difficulty will show
up very quickly! There are some spark plugs that will give you slightly
better performance than an NGK - but only for a little while. The humidity,
air pressure and temperature have to be exactly the same as when the engine
was tuned. so......... in my experience, NGK spark plugs will run better,
longer than any other make and are more tolerant of atmospheric changes.
P.S. I also use them in my SCCA MGB "E" Production race car that now makes
175-180 hp on a dyno (up from 90-98 hp stock)
