Which spark plugs are better NGK or Denso?
Denso plugs are installed on almost every automobile model manufactured in Japan. The iridium used in them has a superior hardness. The electrode’s diameter in Denso plugs shrinks more than an NGK. For this reason, Denso plugs do not last longer than NGK units, but they are better at producing powerful sparks.
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.
How long do Denso iridium plugs last?
60,000 to 80,000 miles
Denso Iridium Power series has an iridium center electrode with a traditional nickel ground electrode construction. Therefore, the ground electrode will wear out first. Typically we have found you can expect to get 60,000 to 80,000 miles on an unaltered motor.
How long do Denso ignition coils last?
Go with Denso if you want no coil issues for at least 100k miles.
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.
What kind of spark plugs do Toyotas use?
“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. DENSO Iridium Power plugs, with their .4mm center electrode, have been developed for performance applications.
Is the 6 cylinder spark plug the same as the NGK?
The 6 and 4 cylinder engines should be using the same plug, just let the parts counter know your car’s information. Be sure to check gap of the plug. Most plug manufacturers sell plugs in pre-gapped version, such as NGK with a part number then the last digits, separated with ‘-‘ specify the gap.
Which is better ik20 or NGK spark plugs?
The IK20 however, is just a regular shorter life plug without the ground pad. You’ll get less iridium and less platinum than NGKs in general. 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.
