Both NGK and Denso spark plugs are designed to be direct replacements for Toyota's original equipment, making installation straightforward and ensuring a proper fit.
Performance and Durability
- NGK: NGK spark plugs are known for their excellent performance, with features like the V-Groove and U-Groove electrodes helping to improve combustion efficiency and reduce fouling. They are also highly durable, with a long service life.
- Denso: Denso spark plugs are also renowned for their performance and durability, with advanced electrode designs and premium materials ensuring reliable ignition and long-lasting performance.
Both NGK and Denso spark plugs are excellent choices for Toyota vehicles, offering high-quality performance and durability that meet or exceed the original equipment standards.
Conclusion
When it comes to choosing between NGK and Denso spark plugs for your Toyota, there is no clear-cut "better" option. Both brands are highly respected and offer excellent quality, performance, and durability. The choice ultimately comes down to personal preference, availability, and any specific requirements or recommendations for your Toyota model. Whichever brand you choose, you can be confident that you're getting a high-quality spark plug that will provide reliable performance and long service life for your vehicle.
What is the best spark plug for high mileage?
Iridium Spark Plugs: Iridium spark plugs are known for their durability and longevity, often lasting up to 100,000 miles or more.
Why are ngk spark plugs better?
NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal.
What are the benefits of DENSO spark plugs?
There is less ignition failure due to misfiring in various operating areas, and the combustion conditions are vastly improved. For this reason, combustion is often improved. Because engine performance is enhanced, acceleration is better than with normal spark plugs.
How long do Denso spark plugs last?
120,000 miles
All Denso long life iridium spark plugs are an OEM design, made for a specific engine. Some feature a special resistor or electrode design, depending on the OE requirements. In their OE application, Denso's long life plugs can last up to 120,000 miles.
What is the number 1 spark plug?
The number one spark plug is always found in the number one cylinder of the engine (or the number one *rotor* in a Wankel). Look at the end of the engine closest to the accessory drive. From there, locating cylinder one is easy for any inline configuration.
What spark plug is recommended for Toyota?
Dual-Ground Electrode Spark Plugs
With that in mind, the ideal spark plug for TDI-equipped Toyotas is the Dual-Ground Electrode design, which delivers optimum performance and durability while maintaining the original recommended change interval.
Why are NGK spark plugs better?
NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal.
How long do DENSO spark plugs last on a Toyota?
Typically we have found you can expect to get 60,000 to 80,000 miles on an unaltered motor. However, because gradual wear will "round-off" firing points over time, the concentrated firing power and voltage requirement benefits will be reduced. For this reason, Denso advises replacement after 30,000 miles.
Which brand spark plug is best?
Bad spark plugs undermine your engine's performance. Some of the best spark plug brands are NGK, Bosch, AC Delco, Denso, Champion, and GenuineXL. Factors you should consider when purchasing new spark plugs are the thread size, recommended use, and cost.
Is DENSO better than NGK?
NGK Plugs are better. They have better threads and the Denso have been known to fall apart in Turbo applications. I went thru this when I replaced the plugs in my Hondas.
