1、电装火花塞常见问题:FAQ OF Denso spark plug #1 Q) How do I read the temperature levels on DENSO Spark Plugs?Shumatt Auto Engineer Answer: The higher the number, the colder the Denso spark plug.#2 Q) Do all DENSO Spark Plugs have a removable terminal nut?Shumatt Auto Engineer Answer: No, only certain part numb
2、ers and applications.#3 Q) After modifying my engine, what DENSO Spark Plug should I use?Shumatt Auto Engineer Answer: That is dependent on the engine modifications that were performed. Always start at the stock heat range and refer to the specifications of the performance part suppliers. Generally,
3、 go one heat range colder for every 75-100 Horsepower increase. This is only good for internal engine modifications, add-on nitrous, supercharger, or turbocharger. The heat range does not have to be changed on bolt-on items such as: air intakes, exhaust (mufflers), or throttle bodies.#4 Q) What is t
4、he purpose of the DENSO U-groove design?Shumatt Auto Engineer Answer:The U-Groove design on the ground electrode allows for a larger flame front and improved ignitability.#5 Q) What is the standard life expectancy of the DENSO Spark Plugs?Shumatt Auto Engineer Answer:The life of the plug depends on
5、the conditions and amount of modifications to the vehicle. The more power that is added the shorter the life of the plug. Generally, Standard/Resistor plugs 30,000 miles; Platinum plugs 60,000 miles; Iridium Long-life 100,000 miles and Iridium Power 30,000 miles.DENSO Spark PlugsDENSO is one of the
6、worlds leading manufacturers of spark plugs. Trusted by all the major auto manufacturers, we have a spark plug for just about every application and purpose: passenger cars and trucks, racing, marine, motorcycles and power sports, industrial and small engines. No matter what kind of spark plug you ne
7、ed, DENSO meets all the requirements and more.The Original U-GrooveEven DENSOs “standard“ spark plug is something special. The innovative design that helped to make DENSO spark plugs famous, the U-groove plug employs a unique, channeled ground electrode designed to generate a larger spark nucleus at
8、 the point of ignition. Greater spark energy than ordinary plugs means improved flame travel, producing more complete, consistent, and efficient combustion.Original U-Groove Denso Spark PlugsSpark plugs are not all alike. With the world-famous DENSO U-Groove spark plug its easy to see, thanks to its
9、 patented U-shaped ground electrode. The U-Groove forms a channel for the spark nucleus to form at the instant of ignition, limiting quenching to generate a more potent spark.

18、hardly content to rest on that achievement. While conventional platinum plugs use platinum only the center electrode, the DENSO Double-Platinum plug features platinum on both the center and ground electrodes. The precious metal fights corrosion and erosion, ensuring superior spark performance and ma
19、ximum spark plug life.Double Platinum Spark PlugsPlatinum is one of the rarest metals on earth and one of the most valuable. However, it also happens to be an excellent material for spark plugs, thanks to its superior resistance to corrosion and erosion in harsh environments like those inside modern
20、, high-tech engines. DENSO Double Platinum spark plugs incorporate the precious metal on both the center and ground electrodes, not just on the center electrode as with conventional platinum plugs. The result is a significant improvement in spark plug life. DENSO engineering studies show that Double
