Are NGK platinum plugs good?
Our Verdict. For a high-quality spark plug, consider the NGK 6619 Iridium IX Spark Plugs, featuring excellent performance, power, efficiency, and reliability. Or, choose the Denso 4504 PK20TT Platinum Spark Plugs, an affordable platinum spark plug that delivers excellent durability and performance.
Do NGK platinum plugs need to be gapped?
It is always best to check the gap against the manufacturer’s specifications. If adjusting the gap on fine wire or precious metal plugs such as platinum or iridium, be very careful not to apply any pressure or prying force to the fine wire center electrode or insulator as they can be damaged.
Is ruthenium better than platinum?
Ruthenium metal is being used in manufacturing spark plugs to resist corrosion and wear better than palladium or platinum. This means that your engine will operate more efficiently and be more durable with ruthenium spark plugs. What is this?
Do iridium plugs burn hotter?
Denso Iridium Power plugs feature the heat range at the end of the part number. For example, IK20 has a heat range of 20. Denso plugs get colder the higher the number, hotter the lower the number.
Are platinum spark plugs worth it?
Since platinum is harder, it holds its sharp edge much longer than a conventional spark plug, up to 100,000 miles. Longevity is a key advantage of platinum spark plugs. Another advantage of platinum spark plugs is that they run a little hotter, which burns deposits off the spark plug better and helps prevent fouling.
Are platinum plugs better than copper?
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.
