0000089333 00000 n Conversely, if the engine is to be operated at low speeds or at low temperatures for long periods, a hotter heat range might be needed to prevent fouling. Fouling can occur more easily if the air-fuel mixture is not adjusted to compensate for the altitude. If the heat range is not optimal, then serious trouble can be the result. 3341 0 obj <>stream Higher cylinder temperatures near the knock level will bring the spark plug firing end temperature closer to the pre-ignition range. 1223 New Genuine NGK SPARKPLUGS USD 95.70 4x NGK SPARK PLUGS Part Number CMR6A Stock No. NGK CMR6A - Possible . I'm no expert so I could be totally wrong, but I found over the years that the manufacturers usually spec the right heat range plug unless you have made major mods to the engine your self. A colder heat range spark plug may be necessary due to the increased cylinder temperature as boost pressure (manifold pressure) and subsequent cylinder pressure and temperature increase. * VISUALLY EXPLAINED by Craig Kirkman, a renowned you tube educator of these systems. The spark timing can be advanced further because ethanol blend fuel has a higher resistance to knock (higher octane). If an air-fuel ratio meter or gas analyzer is not available, it will be necessary to visually inspect the spark plugs frequently during the tuning process to determine the proper air-fuel mixture.

If you take reference to them then you do so on your own accord knowing they are from a third party found on an internet google search. INDEXING. Be the first to write a review. It is most often caused by the wrong (too hot) heat range spark plug, and/or over-advanced ignition timing. The insulator nose of a hotter spark plug has a longer distance between the firing tip of the insulator and the point where insulator meets the metal shell. Indexing is done by placing (usually copper) washers of varying thickness on the spark plug shoulder, so that when the spark plug is tightened, the plug will rotate a certain amount, and gap will point in the desired direction.
