Do Iridium spark plugs make a difference?
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.
Do iridium plugs make more power?
Greater engine power from iridium spark plugs The spark plug manufacturers are unanimous about the fact that iridium spark plugs can considerably improve the engine power. The advantage is crucial when you need to navigate through difficult driving situations or climb steep slopes.
How do I know if iridium plugs are worn?
Iridium spark plugs – Lifetime Symptoms of worn spark plugs: A few misfires (but with no ODBII code generation) upon slight acceleration from speeds between 40 to 60 Km/h. Fuel consumption increase. Rough idle when engine is cold, although this symptom is common to so many other failures.
Do iridium plugs burn hotter?
Denso Iridium Power plugs feature the heat range at the end of the part number. Denso plugs get colder the higher the number, hotter the lower the number. Starting with part # IK20 (heat range 20), a colder plug would be # IK22, a hotter plug would be # IK16.
Do iridium plugs need to be gapped?
In most cases your Iridium Power plugs do not need to be gapped. Should you decide to re-gap your Iridium Power plug, use extreme caution as improper gapping may damage or destroy the Iridium center electrode or porcelain center.
Does Prius need tune up?
The only tune up needed on a Toyota Prius is the gasoline engine. Like any other gas engine you just follow the same routine like other cars. Modern gas engines require tune up every 100k miles!
How often should you change NGK iridium spark plugs?
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.
How long do iridium sparkplugs last?
Replacement spark plugs should usually be the same type (platinum or iridium) as the original if they are expected to last 100,000 miles. Standard spark plugs are only good for about 40,000 miles. On some applications, a double-platinum or double-iridium spark plug may be recommended.
Are spark plugs hotter 7 or 8?
Champion plugs are hotter the higher the number, colder the lower the number. Starting with part # RCJ7Y (heat range 7), a colder plug would be # RCJ6Y (heat range 6), a hotter plug would be # RCJ8Y (heat range 8).
What kind of spark plug does a Toyota Prius use?
It’s important to choose the right kind of plug for your make and model, which is why our Toyota Prius spark plug is precisely configured for your exact engine. Using a strong ceramic insert, it isolates your required voltage with the right amount of cylinder surface contact.
Which is better for spark plugs iridium or platinum?
These spark plugs have many benefits: 1 Smaller center means higher firing performance 2 Iridium has a 1200ºF higher melting point over platinum 3 Iridium plugs last up to 110,000 miles longer than conventional spark plugs
Where are the spark plugs in a Toyota?
Spark plugs are a serviceable, yet extremely important, part of your Toyota’s engine. They sit inside the cylinder head where they create the spark that ignites fuel — the combustion that enables your engine to run. Spark plugs that have outlived their time will cause misfires in your engine — robbing it of efficiency and performance.
