This Zenoah K285072110 spark plug cap is a replacement item intended for use on G230PUH and G230PUM engines and is supplied without retail packing as stated in the product title. It provides the insulated connection that allows ignition current to pass from the lead to the spark plug during operation.
The product listing specifies compatibility with G230PUH and G230PUM only; do not presume fitment on other engine families without confirming part interchangeability through part numbers or the service manual. The cap is noted as a replacement for part #505042901 where applicable.
Fitment is simple: remove the ignition lead, press the cap onto the spark plug until it seats, and check for a secure electrical connection. Regular checks for corrosion or loose contacts will prevent intermittent ignition and support reliable running during tuning sessions.
Keep this cap as a spare for nitro RC cars, boats, or other applications where dependable ignition is required. As the item is sold without packaging, store and manage it as an individual replacement component.
