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 numbers 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 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 the 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 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 Plugs DENSO is one of the world s 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 need DENSO meets all the requirements and more The Original U Groove Even DENSO s 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 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 Plugs Spark plugs are not all alike With the world famous DENSO U Groove spark plug it s easy to see thanks to its 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 The premium features don t stop there DENSO s distinctive five rib insulator in purified alumina prevents leakage and flashover while dual internal copper glass seals and a copper core center electrode with nickel alloy tip assure reliable spark delivery To keep your engine running smoothly its spark plugs must fire 25 times a second or more If just one spark plug skips a beat you ll know it instantly with rough running poor acceleration and reduced fuel economy DENSO U groove spark plugs combine dependable performance and superior value FEATURES 100 percent pre fired to ensure reliable operation Copper core center electrode for superior thermal conductivity Unique five rib insulator reduces flashover BENEFITS Patented U groove ground electrode design fires leaner mixtures than conventional plugs Precision machine rolled threads reduce seizing and cross threading in delicate aluminum heads Wide range of part numbers for thousands of applications including classic and collector cars Platinum TT Contemporary spark plugs may employ precious metals like platinum on the center electrode The platinum Twin Tip plug raises the bar with DENSO s special platinum alloy on the center electrode and a titanium enhanced alloy on the ground electrode The standing ground electrode reduces spark quenching producing more effective ignition while the durable alloys extend spark plug life The DENSO Platinum TT spark plug is designed to provide top performance and total value Platinum TT Spark Plugs In DENSO s Platinum TT spark plug the TT stands for Twin Tip It s one step beyond traditional platinum plugs with premium materials on both electrodes instead of only one The 1 1mm platinum center electrode is augmented by a titanium enhanced ground electrode delivering maximum ignition energy under the fiercest conditions an engine s combustion chamber can dish out Along with the materials the design is unique as well The ground electrode s free standing firing pad reduces quenching to generate a more powerful spark The Platinum TT is designed to offer superior consumer value along with faster starts and improved economy DENSO s objectives Top Performance Total Value FEATURES 1 1mm platinum center electrode Titanium enhanced alloy ground electrode Minimum quench electrode design BENEFITS Improved fuel economy Faster starts Enhanced flame propagation for increased engine efficiency Double Platinum DENSO was the pioneer in introducing platinum spark plugs to the automotive aftermarket but was 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 maximum spark plug life Double Platinum Spark Plugs Platinum 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 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 Platinum plugs can run longer with reduced erosion minimizing spark gap growth throughout the life of the plug The bottom line your car can run better longer FEATURES Platinum center electrode Platinum ground electrode Premium shell construction with machine rolled threads BENEFITS Sustained spark performance over 60 000 miles Reduced secondary required voltage increased ignition efficiency Satisfied customers reduced shop comebacks Iridium Long Life DENSO s Iridium Long Life spark plug is standard equipment with a number of automakers including GM Toyota Honda and Mitsubishi DENSO s patented iridium alloy is more durable than even platinum allowing the center electrode to be shrunk to only 0 7 mm in diameter This produces a dramatic improvement in ignitability and spark plug life Iridium Long Life Spark Plugs Closely related to platinum and exhibiting even tougher qualities the rare metal iridium is an ideal material for spark plugs The DENSO Iridium Long Life plug was specifically designed for long service life and consistent performance in the latest most advanced production cars A fine wire 0 7mm iridium center electrode is 360 degree laser welded in place using an exclusive DENSO process then matched to a platinum ground electrode This pair of precision formed premium metal electrodes dramatically extend the plug s useful life The DENSO Iridium Long Life plug has been selected as original equipment on many of the world s top cars including those from GM Toyota Honda and Mitsubishi There s a simple reason for that these manufacturers needed the best FEATURES Fine wire iridium center electrode Platinum ground electrode 360 degree laser welded spark tip BENEFITS Sustained spark performance over 100 000 miles Withstands higher pressures and temperatures Reduced spark plug wear and erosion Iridium Power DENSO Iridium Power spark plugs represent a performance breakthrough The laser welded center electrode is only 0 4mm in diameter the slimmest iridium electrode in the industry The taper cut side electrode complements the design delivering reliable spark energy under the most grueling pressures and temperatures Iridium Power Spark Plugs For some applications iridium can be six times harder and eight times stronger than even platinum and it can withstand temperatures of greater than 4 000 degrees Fahrenheit DENSO engineers used the power of this miraculous metal to produce an iridium center electrode that is only 0 4mm in diameter With its superior thermal qualities this whisker fine electrode is capable of taking the most extreme heat and punishment This breakthrough was matched to one of DENSO s most famous innovations the patented U Groove ground electrode The combination of these two features resulted in the Iridium Power plug one of the most advanced and innovative spark plugs on the market Just one of its many attributes The Iridium Power plug delivers greater spark energy while demanding significantly less secondary required voltage
