does not match NGK CPR7EA-9

About Me Mechanic

Pros

  • None

Cons

  • Tip Is Not Extended

Best Uses

  • Only For Exact Fit

Comments about Autolite Copper Spark Plug:

This does not match the NGK CPR7EA-9 Spark plug. The tip is extended on the NGK. This Autolite has a recessed tip. Thus not getting the spark into the cylinder head as designed by the manufacture.
Was being used on a Kawasaki Valcan 900.
