Can old cars use iridium spark plugs?
Yes, it is. Also, older vehicles may well be suffering such problems as reduced ignition coil performance. An iridium spark plug with low required voltage uses the energy of the coil effectively for efficient combustion of the air-fuel mixture.
Do NGK iridium spark plugs increase horsepower?
Increase your performance. Iridium plugs take less voltage to fire which results in more coil dwell time. That translates to better combustion, lower emissions, better fuel economy and more horsepower.
Can iridium spark plugs cause misfire?
Spark plugs may be one of the main causes of engine misfires, but with the use of iridium in the design of spark plug fine wire, it addresses misfires like never before. It provides fewer chances of misfires because of the metal that protects against high temperatures, oxidation, and corrosion.
Can I upgrade to Iridium spark plugs?
Starting your car in the winter Winter starts can seriously decrease your car’s performance, and also run the risk of spark plug fouling. Upgrading your spark plugs to an Iridium fine wire plug will provide instant starts in cold weather and help eliminate the risk of fouling.
Can you use Iridium spark plugs instead of 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.
Are NGK spark plugs good?
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 often should NGK iridium spark plugs be changed?
Therefore, NGK gives them a life expectancy of 40-50k miles and Denso assigns a recommended replacement interval of 30k miles.
Do Toyota 4Runner spark plugs wear out?
One of the reasons why your Toyota 4Runner is capable of delivering such a strong and superior performance each and every time you start it is because of its top-notch spark plugs. Of course, as those plugs start to wear out, their reliability and efficiency quickly diminishes your engine’s ability to function properly.
What kind of spark plugs should I put in my Toyota?
The only spark plugs you should ever put in your Toyota with a 3.4l engine is the Denso or NGK dual electrode OEM spark plugs. Do not mess around with Bosch, Autolite, or any other brand they try to sell you at your local auto parts store.
Do iridium spark plugs affect performance?
Whether or not the change impacts your overall performance will depend on several variables. The vehicles and engines that benefit the most are the ones that have a close iridium spark plug match with a similar overall design. You’re also replacing a standard one with a basic copper plug, and the engine has a significant cylinder capacity.
What are the best spark plugs for a TDI engine?
Introduced in 1994, this system promotes greater combustion efficiency by firing the spark plugs twice as often as a standard ignition. With that in mind, the ideal spark plug for TDI-equipped Toyotas is the Dual-Ground Electrode design, which delivers optimum performance and durability while maintaining the original recommended change interval.
