1982 Honda CB900F · Ignition Buying guide
Honda’s 1982 CB900F addendum specifies NGK DR8ES as the standard plug. NGK’s published replacement table identifies DR8EA as its replacement. Coils, spark units, leads and caps still need diagnosis separately when investigating a misfire.

The Rick’s replacement coil has wires attached; coil 17-6803 requires separate 7mm high-tension leads. Aftermarket ignition systems have their own coil-resistance and suppression requirements. Do not select a lower-resistance coil or a different cap arrangement simply because it appears in this category.
The DR8EA listing is a conventional resistor plug; DR8EIX is the separately listed Iridium IX option. Match the full designation and the correct gap for the application. Do not choose a different heat range or expect a guaranteed horsepower increase from a material change.
Honda’s 1982 addendum specifies DR8ES. NGK’s 2021 South African catalogue lists DR8EA as its replacement. Check the applicable recommendation for another market or a modified engine before choosing a different plug.
Inspect the plugs, caps, leads and wiring and follow the Honda ignition tests first. A single ignition channel can affect a pair of cylinders, but several components share that circuit. Match replacement coils to the installed ignition’s electrical requirements.
