Denso spark plugs are standard on many foreign vehicles. For example, the auto concern Toyota has been cooperating with this manufacturer for many years. These candles are distinguished by their reliability and quality, therefore, when buying them, it is important to distinguish an original part from a fake.
Instructions
Step 1
When buying Denso candles, pay attention to the packaging, which must have an impeccable design. Inscriptions and drawings should be clear and not on folds. After visual inspection, open the packaging and take the candle out. Take a closer look at the center electrode, which should have a clear cylindrical shape and be set exactly in the center. If these conditions are not met, in front of you, most likely, a fake.
Step 2
Also, a sign of poor-quality products is poor electrode surface treatment, the presence of roughness and other defects. The side electrode should also be level. The terminal nut of a counterfeit product is very easy to remove. Check that the rod and insulator are firmly seated and that the surface of the frame is properly finished.
Step 3
Remember that a shiny pin is a sign of a phony part. Pay particular attention to the markings, which must be bright and legible. Try to scrape it off with your fingernail - if you succeed, then this is another fake.
Step 4
The ceramic insulator on the original part has no visible defects, while visible air bubbles can be found on the fake, which will negatively affect the heat dissipation. The electrode plug is bright copper in color and has excellent thermal conductivity.
Step 5
Pay attention to the cost of candles - often counterfeits are sold at a price that is significantly lower than the one set by the official dealer. Before going to a car shop, find out on the Internet or from specialists the approximate cost of the original product. Always be attentive to the choice of spark plugs for your car, because the service life of the vehicle depends on their quality and reliability.
