Ignition Leads

To order the correct lead, select the ignition lead model from the table below based on your magneto type.

Example: An engine with 5⁄8 x 24 spark plugs and a Scintilla S6 Series magneto with threaded cap uses a 101 model lead.

NOTE: Threaded high tension terminal plates must be used when upgrading from unshielded to shielded ignition leads.

Magneto Selection Spark Plug Selection • 5/8 x 24
Eisemann LA-4 and LA-6 Use model 102
Scintilla SF-4 and SF-6 Series Use model 104
Scintilla S4 and S6 Series with Threaded Cap Use model 101


Find the Correct Lead Length

If you are replacing an existing lead, measure the exact length, ferrule-to-ferrule, and use this as the last part of your order number. Leads are manufactured in 3” increments from 19” to 60”.

Example: If you need a 101 Series lead and the ferrule-to-ferrule measurement is 33 inches long, the Univair part number would be 101-33.
