Glow Plugs. The NGK spark plug finder helps find the right spark plug via the NGK spark plug codes. Any use of this cross reference is done at the installers risk. NGK spark plugs are original equipment on many outboard motors and are excellent replacements for everyday engine maintenance. /* script places appropriate kudos statement into page */ NGK SPARK PLUG prides itself on providing cutting-edge products, first-class expertise and technical know-how related to spark plugs, glow plugs, ignition coils and leads, oxygen, temperature, NOx and MAP/MAF sensors. The experienced tuner can analyze these symptoms to track down the root cause of many problems, or to determine air/fuel ratios. Reach, Gasket Seat, Each Part Number: NGK … Look at end of the spark plug that was in the cylinder and examine it. When traveling at a consistent high rate of speed, or carrying/pushing very heavy loads, a colder heat range spark plug should be installed. Compression can be increased by performing any one of the following modifications: reducing combustion chamber volume (i.e. Spark plugs are the “window” into your engine (your only eyewitness to the combustion chamber), and can be used as a valuable diagnostic tool. A Fun Old Porcelain Sign and The NGK spark plug finder helps find the right spark plug via the NGK spark plug codes. Fast shipping and great service! //-->, Changes are periodically added to the information herein. NGK’s family of automotive products are driven by extreme dedication to innovation, performance and quality. The temperature at this point is where the accumulated carbon and combustion deposits are burned off. NGK always works very closely with the engine manufacturer to ensure a perfect match between spark plug and machine. The spark plug Cross references are for general reference only. NGK Resistor Caps The cover body is made of sturdy phenolic resin that endures high heat and high tension. Technical. The rate of heat transfer is determined by: A spark plug’s heat range has no relationship to the actual voltage transferred though the spark plug. It is possible, with care, to decode the construction of Champion sparkplugs. we recommend ngk instead, and traditional electrode-gap rather than surface-gap plugs where possible. document.write(name); If the piston can’t go up (because of the force of the premature explosion) and it can’t go down (because of the upward motion of the connecting rod), the piston will rattle from side to side. Glow Plugs. The temperature of the spark plug’s firing end must be kept low enough to prevent pre-ignition, but high enough to prevent fouling. Please view the application guide below. The borderline between the fouling and optimum operating regions (500°C) is called the spark plug self-cleaning temperature. The resulting shock wave causes an audible pinging sound. We are not NGK Spark Plugs USA. As humidity increases, air intake volume decreases. Take the spark plug in your hand and begin looking at it for signs of damage. Please review our Warranty, Returns & Refunds policies before you place an order. Use Cross References as a guide only. Don't just ask for a spark plug, insist on NGK. This creates higher cylinder pressures/temperatures and causes an increase in the spark plug’s tip temperature. The insulator nose length is the distance from the firing tip of the insulator to the point where insulator meets the metal shell. There are three basic diagnostic criteria for spark plugs: good, fouled and overheated. EXCEPTION: NGK Racing Plugs: (Any NGK plug that begins with the letter “R”) For NGK Racing Plugs, the heat range is located AFTER the hyphen. NGK Spark Plug Numbering Systems Wondering what the numbers and letters on an NGK spark plug mean? The first step is removing the spark plug you want to look at. document.write(city); Numerous questions have surfaced over the years, leaving many people confused. In all VRO-equipped motors, the "Q" type plug is recommended (Designated by "Z" in the plug number for NGK). Our ignition parts cover 95% of import and domestic vehicles and are engineered to the highest durability and operational standards to meet or exceed OE requirements. Mastertech may make improvements to this site at any time. Since the insulator tip is the hottest part of the spark plug, the tip temperature is a primary factor in pre-ignition and fouling. Read full disclaimer. Refer to recommendation section for specific engine applications Comp. The world leader in spark plug technology for over 80 years. View full size version of NGK spark plug numbering chart. NGK Glow Plugs All NGK Glow Plugs are manufactured to the highest level of quality to ensure quick and consistent starts. //-->. document.write(state); Our technical support is an integral part of the many services we provide. The heat range measurement is determined by several factors; the length of the ceramic centre insulator nose and its’ ability to absorb and transfer combustion heat, the material composition of the insulator and centre electrode material. To contact them, click here. The spark plug cannot create these conditions, but it must be able to cope with the levels of heat…if not, the performance will suffer and engine damage can occur. to get great parts for your outboard? Normal spark plug Spark Plug Cross Ref. The colder type removes heat more quickly, and will reduce the chance of pre-ignition/detonation and melting or damage to the firing end. Ancient Tools, Meet the MasterTech! While every precaution has been taken in the compilation of this information, NGK Spark Plug (Australia) Pty Ltd takes no responsibility for inaccuracies that may occur within it. Follow these instructions on how to remove a spark plug. Failure to select a colder spark plug can lead to spark plug/engine damage, Advancing ignition timing by 10° causes tip temperature to increase by approx. The firing end appearance also depends on the spark plug tip temperature.
