Engine News, SEBD9564, 03 November 2008, "An Improved Spark Plug Extension is Used". Disregard the article, refer to the following article.Description of Change: An improved spark plug extension is used. The new extension increases the dielectric strength in order to help prevent damage due to arcing. The new extension prevents the steel rod from moving inside the extension. This ensures good contact between the spark plug and the extension. Another feature of this new extension is an O-ring seal at the connection for the transformer. This O-ring seal helps to prevent arcing between the extension and the transformer.Adaptable To: The 283-5269 Transformer Gp is canceled and replaced by the 310-3180 Transformer Gp. Refer to Table 1.
