Iridium Spark Plugs
Iridium is a more durable material than platinum (its melting point is approximately 1200°F higher than platinum). Iridium spark plugs last longer than conventional spark plugs—up to 110,000 miles.
What are the best brand of spark plugs for Toyota?
As the rule goes, it’s best to stick as close to OEM as possible.
If you want to be 100% OE, you can go with these genuine Toyota plugs.This NGK spark plug is the newer iridium type that will last longer than the original Toyota. If you want platinum for the RAV4, I recommend you stick to NGK G-Power BKR6EGP.
How long do Toyota Corolla spark plugs last?
Spark plugs come in three basic types: Iridium plugs, which can go 100k+ miles before requiring replacement (available on select Toyota models) Platinum plugs, which can go 50-60k miles before requiring replacement (available on select Toyota models) Copper plugs, which can go about 20k miles.
What spark plugs are better than NGK?
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.
Which is 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 these plugs shrinks more than an NGK. For this reason, Denso plugs won’t last longer than NGK units but they will be better at producing powerful sparks.
Which is better iridium or platinum spark plug?
Iridium is arguably eight times stronger and six times harder than platinum. It has a higher melting point of about 700 degrees compared to platinum. Platinum spark plugs wear out faster than iridium spark plugs. Iridium plugs are said to be more durable compared to platinum plugs up to 25% more.
How long do NGK iridium plugs last?
NGK gives them a life expectancy of 40-50k miles. But they have to temper their projections as driving conditions and motor modifications differ. Typically we have found you can expect 60,000 to 80,000 miles on an unaltered motor. NGK Laser Iridium Spark Plugs have iridium center and a platinum ground electrodes.
Do expensive spark plugs make a difference?
High performance
Noble metal plugs can perform consistently and well, which helps to maintain the engineered performance of the engine. They won’t make the engine perform better than it did when it was new, but they will help it stay at that level longer.
Is NGK a good brand?
With over 8 decades of experience, NGK is one of the biggest names in spark plugs. Years of experience creating specialized sensors, connectors and other car engine components have helped earn NGK a reputation as a trusted brand noted for quality and consistency.
How do I know if my spark plugs need changing?

Does Toyota use NGK or Denso?
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.
Are iridium plugs worth it?
It has a high melting point, which also means that it can produce great electrodes while retaining its fine characteristics, Iridium spark plugs gives you better performance, complete combustion and excellent longevity which makes you free from change your spark plugs frequently.
Which is better iridium or ruthenium?
Iridium has more platinum levels than Ruthenium which gives the plug a higher melting point. Therefore, the iridium plug is more durable and high resistant to oxidation and corrosion. If you want your machine to run efficiently for years, the iridium spark plug is your best choice.
What spark plugs are better than iridium?
Platinum spark plugs are surely more durable than their copper counterparts. However, they are less durable than iridium spark plugs so you may have to change the platinum ones sooner. If your priority is durability, then platinum spark plugs will not cut it for you. Spend a bit more and go for iridium ones.
Are NGK Spark Plugs Made in Japan?
