Is Denso 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.
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.
Which is better iridium or platinum spark plug?
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.
Which is better copper or iridium spark plugs?
Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity.
Is DENSO owned by Toyota?

Are Denso Spark Plugs made in China?
All DENSO Spark Plugs are manufactured in Japan, Indonesia, China and USA. If a part claims to be a DENSO component but has been manufactured outside of these areas, then it is not genuine. … Always check, and if in doubt, call your local DENSO representative who can advise.
Is DENSO a good brand?
Denso is well-known and has a good reputation overall, but so does NGK and so do a number of other top-tier aftermarket (from the perspective of Toyota, but OEM for others) brands.
Are Denso Spark Plugs pre gapped?
DENSO spark plugs are manufactured with a pre-set gap. With nickel plugs, especially with motorcycles, the gap may need adjustment. 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.
