Opie Oils Limited (all other content, including but not limited to lubricant advice & recommendations). Call us at 713-459-6977. As a result, more heat stays in the ceramic firing end and less is dissipated to the engine. Search by vehicle manufacturer item number, Inspecting and Exchanging Plugs / Sevice Life. Not a problem, just give us a call on 01209 202 949 or use our custom recommendation form and we'll be happy to look into the best possible choice for you. Heat Range Cross Reference Table | Technical Specs Rather, the heat range is a measure of the spark plug’s ability to remove heat from the combustion chamber. The letters refer to the center electrode material, projection … Too hot of a plug will cause preignition, engine knock, and finally detonation. To make things easier we've made this page to explain a few things, here you will find an explanation of heat ranges and how it can effect your engine, plus a cross reference table for heat ranges of some of the most common brands. All rights reserved. Well, below you will find a “heat range cross reference chart” that shows comparisons between 5 major brands of spark … Therefore, output falls and this can reach the level of electrode wear and insulator damage. It must do this in a controlled manner that will: 1. Heat range is the measure of how fast the spark plug tip dissipates combustion heat. Resistor Stock No. The number at the end of the part indicates the gap. If a spark plugs temperature remains too low it can cause loss of ignition spark due to deposit build up on the firing end, which in turn will leave your engine struggling / down on power. Explanation of a Spark Plugs Heat Range from NGK Spark Plugs USA. This web site and all data within is copyright. The heat range of a spark plug is the range in which the plug works well thermally. HAPPY NEW YEAR! Choosing the right heat range is crucial for high performance engines. The heat range of a spark plug is its ability to transfer heat from the combustion chamber to the cylinder head. Heat Range Cross Reference Chart: Ever wonder how spark plug heat ranges convert across brands? Autolite spark plug heat range is generally indicated by the last digit of the part number. Well, below you will find a “heat range cross reference chart” that shows comparisons between 5 major brands of spark plugs. If the heat range is too cold, the spark plug will be unable to properly self-clean by burning off carbon … 2544 is the coldest plug in that plug family, and 2546 is the hotest. Therefore, this type of spark plug is generally used for high speed, high output engines. When the center electrode temperature is 500°C or lower, free carbon generated when the fuel does not combust completely is deposited on the surface of the insulator. [YC] Firing End Design - The letters after the heat rating indicates a special spark plug construction feature called the firing end design. The relationship between the spark plug temperature and vehicle speed and heat range is expressed with a graph like that in the figure. The relationship between the spark plug temperature and vehicle speed and heat range is expressed with a graph like that in the figure. Any violation shall constitute a copyright infringement and shall be subject to prosecution. NOTE: Due to differences in design and materials the plugs listed in cross reference section are … The heat rating is a measure of the amount of heat dissipation.The heat range of a spark plug is the range in which the plug works well thermally. ngk spark plug upgrade chart original plug stock no. Also, since the heat release path from the insulator leg section to the housing is long, heat dispersal is low and the temperature of the center electrode rises easily. A spark plug’s heat range has no relationship to the actual voltage transferred though the spark plug. Low powered engines don't normally produce as much combustion warmth so won't heat up a plug as much or as rapidly as a high BHP vehicle, therefore the plugs have to be designed accordingly so they can reach and not exceed optimum operating temperatures. That is why it is necessary to select spark plugs with the appropriate heat range for the engine characteristics, running conditions, etc. The heat transfer pulls heat out of the combustion chamber and at the same time away from the spark plug tip. Dexron | Follow this link for more information on Determining Correct Spark Plug Heat Range. Don't just ask for a spark plug, insist on NGK. If the heat range is too cold, the spark plug will be unable to properly self-clean by burning off carbon … NGK Heat Ranges - The larger the number after the dash the colder the plug is.
