Bulletin No. SB-773
SUBJECT: AUTO-LITE A2X SPARK PLUG
At the present time, the Auto Lite A2X Spark Plug is no longer
recommended for use in engines over 18 horsepower. However,
tests have verified it is capable of giving maximum performance
in engines of 18 horsepower or lower. Please inform your cust-
omers of this latest recommendation for the A2X spark plug. Use
your inventory of A2X in these lower horsepower engines.
The advent of the high output engines has fostered new develop-
ments in spark plug design that promise greatly improved performance
and spark plug life. As these newly developed spark plugs are
tested and approved for use in our engines, you will be informed
by means of Service Bulletins.
