Description / Abstract:
SCOPE AND PURPOSE: This SAE Standard applies only to
spark plugs used for ground vehicles and stationary engines.
This standard is intended to serve as a guide to dimensions
common to the majority of current production spark plugs and future
applications. It is not the intent of this standard to prohibit the
manufacture of spark plugs having dimensions differing from those
presented. Many applications exist which require specialized or
nonstandard spark plugs. It is recommended that this standard be
used in spark plug design and engine applications wherever
possible. Whenever designs situations arise that prevent the use of
one these standard spark plugs, a spark plug manufacturer should be
contacted for guidance.
