64 Autolite Replaces Champion RN11YC, NGK BPR5ES
I have autolite sparks plugs ARF32M and need to know the cross reference to NGK
I"ve been trying to find an answer to this question myself and belive the Autolite 3924 corresponds to the Champion RC12YC.24-7423 - Champion RC12YC Spark PlugRC12YC Champion Replaces Autolite 3924, NGK BCPR6ES..
NGK - BPR4EY AUTOLITE - 65
Yes you can. If the # on them cross over to the factory plug.
Most all brand spark plug brands are on the cross reference including Champion. Some of the brands that cross reference to Champion are Autolite and Denso,
Rule of thumb. Before 74, Autolite 76, or any cross referenced plug to that. After 74, 26. You will have to lok to tell for sure, because so much small block stuff interchanges. Look at the seat in the hole. If it is tapered, then the 26. If it is flat, then the 76, with the washer.
One can purchase an Autolite spark plug from a local store that carries Autolite products. One can use the store locator on the official Autolite website to find a location near him or her.
