The flame wall has to travel long distances, resulting in incomplete combustion, higher fuel consumption and poorer performance. Our SE Performance ignition system provides a remedy by upgrading to double ignition. In order to install such an ignition system, however, the cylinder heads must be provided with a second spark plug bore. Of course we offer this service in our mechanical workshop.\u003c\/span\u003e\u003c\/span\u003e\u003cbr \/\u003e\r\n\t\u0026nbsp;\r\n\u003c\/div\u003e\r\n\r\n\u003cul\u003e\r\n\t\u003cli\u003e\r\n\t\u003cdiv\u003e\r\n\t\t\u003cspan data-mce-style=\"font-size: 12px;\" style=\"font-size: 12px;\"\u003e\u003cspan data-mce-style=\"font-family: verdana,geneva,sans-serif;\" style=\"font-family: verdana,geneva,sans-serif;\"\u003eCreating the basic hole for the spark plug thread\u003c\/span\u003e\u003c\/span\u003e\r\n\t\u003c\/div\u003e\r\n\t\u003c\/li\u003e\r\n\t\u003cli\u003e\r\n\t\u003cdiv\u003e\r\n\t\t\u003cspan data-mce-style=\"font-size: 12px;\" style=\"font-size: 12px;\"\u003e\u003cspan data-mce-style=\"font-family: verdana,geneva,sans-serif;\" style=\"font-family: verdana,geneva,sans-serif;\"\u003eFree milling outside in the cooling fin area\u003c\/span\u003e\u003c\/span\u003e\r\n\t\u003c\/div\u003e\r\n\t\u003c\/li\u003e\r\n\t\u003cli\u003e\r\n\t\u003cdiv\u003e\r\n\t\t\u003cspan data-mce-style=\"font-size: 12px;\" style=\"font-size: 12px;\"\u003e\u003cspan data-mce-style=\"font-family: verdana,geneva,sans-serif;\" style=\"font-family: verdana,geneva,sans-serif;\"\u003eCutting the corresponding candle thread\u003c\/span\u003e\u003c\/span\u003e\r\n\t\u003c\/div\u003e\r\n\t\u003c\/li\u003e\r\n\t\u003cli\u003e\r\n\t\u003cdiv\u003e\r\n\t\t\u003cspan data-mce-style=\"font-size: 12px;\" style=\"font-size: 12px;\"\u003e\u003cspan data-mce-style=\"font-family: verdana,geneva,sans-serif;\" style=\"font-family: verdana,geneva,sans-serif;\"\u003ePrice per cylinder head\u003c\/span\u003e\u003c\/span\u003e\r\n\t\u003c\/div\u003e\r\n\t\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cp\u003e\r\n\t\u003cspan data-mce-style=\"font-size: 10pt;\" style=\"font-size: 10pt;\"\u003e\u003cspan data-mce-style=\"font-family: verdana,geneva,sans-serif;\" style=\"font-family: verdana,geneva,sans-serif;\"\u003e\u003cspan data-mce-type=\"format-caret\" id=\"_mce_caret\"\u003eConversion of the cylinder heads to a second plug hole for dual ignition.
