The different types of spark plugs in my collection
Design and variations
Spark plugs built to keep the oil away

A great deal of the older spark plugs was built to, in one or another way, avoid clogging up with oil and soot, or they were made easy to clean, be-cause of bad gasoline, engines running to cold, absence of thermostats and engines not well maintained.

With spinning fan as center electrode.
