Product range comprising modified spark plugs of the Super, Extra, and Platin product ranges. The composition of the sales range ensures deployment in most of the modern vehicles on the market.
The spark plugs derived from the Super product range have one ground electrode in the shape of the letter A. The spark plugs derived from the Extra product range have multiple ground electrodes. The A-line product range also includes types with a platinum center electrode from the Platin product range.
