Is DENSO a good spark plug?
While both NGK and Denso are both quality companies that make stellar spark plugs, it comes down to personal choice. You may like one above the other, but both are great spark plug brands, that have durability, longevity, state-of-the-art technology and more. Regardless of any spark plug you buy.
When should I replace my DENSO spark plugs?
Here Gilbert Couvert, Product Manager, Spark Plugs at DENSO Europe Aftermarket advises on all aspects of spark plug replacement. The estimated mileage of standard nickel spark plugs is between 30,000 and 45,000 km, platinum spark plugs around 70,000 km, and double platinum spark plugs more than 80,000 km.
Do DENSO spark plugs need to be gapped?
DENSO spark plugs are manufactured with a pre-set gap. Do not change the gap on platinum, iridium or twin tip spark plugs, as the fine electrodes may get damaged.
How long do Denso spark plugs last?
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 life expectancy of spark plugs?
How long spark plugs last varies by manufacturer and vehicle, but on many vehicles today, they should be good for 100,000 or more miles. Some vehicles, though, will have shorter intervals, particularly performance and luxury models.
What kind of electrode is used in Denso spark plugs?
However, we’ve managed to attach a fine 0.7mm-diameter platinum electrode using a 360° laser welding technique. Using DENSO’s exclusive iridium alloy having a very high melting point, the tip of the center electrode can be shaped very thin and fine, reducing spark voltage requirements and greatly improving ignitability.
What kind of electrode does an iridium spark plug have?
DENSO has started to sell IRIDIUM TT spark plugs having a φ0.4 mm iridium alloy center electrode and a 0.7 mm needle-type platinum alloy ground electrode. The quenching effect has been decreased by forming the electrode into a double needle shape.
How is the quenching effect of an iridium spark plug reduced?
The quenching effect has been decreased by forming the electrode into a double needle shape. As a result, the flame kernel rapidly develops and the engine’s power is drawn out to its maximum potential.
What makes Denso spark plugs last so long?
Using the same laser welding process as the Iridium Power spark plug, DENSO designed a long life spark plug factory-installed on luxury vehicles by automakers such as GM, Toyota, Honda and Mitsubishi. Using its patented Iridium alloy, DENSO was able to shrink the center electrode to 0.7mm, dramatically improving ignitability and longevity.

Where can I get spark plugs for my corolla?
I decided to get NGK from a local auto shop and as usual they are better made clean and up to specs. No need to research, these are the real SC20HR11 spark plugs. I bought them for my 09 Corolla and they fit perfectly to replace the SC20HR11s which came factory.
Are DENSO spark plugs pre gapped?
DENSO spark plugs are manufactured with a pre-set gap. Always use a special spark plug gapping tool to change the gap. Do not change the gap on platinum, iridium or twin tip spark plugs, as the fine electrodes may get damaged.
Which DENSO spark plug is the best?
Denso Platinum TT Plug
1. Editor’s Pick: Denso Platinum TT Plug. Combining advanced technologies, improved efficiency and performance, and the reputation of one of the biggest names in spark plugs, the Denso Platinum TT spark plug range is one of the best-selling spark plugs available.
Are DENSO spark plugs OEM?
DENSO has been one of the world’s leading pioneers of OEM quality spark plug technology since 1959. Continuous R&D work has achieved additional patented technologies for Aftermarket.
Do you need to gap NGK iridium spark plugs?
In most cases your Iridium Power plugs do not need to be gapped. Should you decide to re-gap your Iridium Power plug, use extreme caution as improper gapping may damage or destroy the Iridium center electrode or porcelain center.
Which is a better spark plug platinum or iridium?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
Are platinum plugs better than iridium?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
What kind of spark plug does a Toyota Tacoma use?
Brand-new spark plugs for Toyota Tacoma use a ceramic component to separate the high voltage at the electrode, making sure the spark occurs at the electrode tip and nowhere else. Different vehicles require different temperature plugs, and your Toyota Tacoma manufacturer knows the right one for your rugged rig.
What’s the difference between Denso and NGK spark plugs?
NGK and Denso are both fine plugs. Toyota uses both brands in manufacturing. On the V6, sometimes you see one bank with Denso and the other with NGK. IMO, get which ever one costs less because you won’t notice any difference between the NGK and Denso.
Why do Toyota spark plugs have an you shaped groove?
The name explains the design of this plug — it uses a U-shaped groove in the ground electrode. This u-groove traps the air/fuel mixture before the spark plug fires, making for a large spark, reducing fouling, and making for more efficient combustion. Available for select models, this design has several benefits:
What’s the life of a Toyota spark plug?
However, one advantage is the slightly thinner center electrode (0.4mm) but probably with a shorter life than the 0.7 mm spec’ed for Toyota. “Toyota models carry an ultra long-life Iridium plug variation (.7mm with platinum tipped ground) that is capable of up to 120,000 miles of service.
