1928 Buick Roadster-Spark Plugs


Recommended Posts

If you can clean and keep these AC C77L it would be best. The only AC style replacements are Motorcraft 3076s and they are of a shorter reach. Even these 77L plugs may have longer electrode /body and top connector than original. (Early style plugs were shorter.) They will need a connector boot or other insulation to live under the factory spark plug cover. I know the AC TITAN   No. SAEL (S.A.E. Longwas what was original equipment for my 1925 Buicks. Later designations were AC 77.
