Do Iridium spark plugs increase horsepower?

Better yet, upgrade to a Double Platinum or Iridium Spark Plug to increase your change interval to 100k miles. 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.

Do NGK Laser Iridium plugs need to be gapped?

They recommend not gapping them because the irridium center electrode is more brittle than most metals and can be fractured or broken. The ground electrode (the hooked one) is actually platinum and can be bent carefully, but to be honest I’d just leave them be. They should be preset.

What is the difference between Iridium and Laser Iridium spark plugs?

Should you grease spark plugs?

It’s very important not to over or under tighten spark plugs during installation. … If your engine has the more modern ‘COP’ system (coil-on-plug) then lube the spark plug boot with dielectric grease, this helps prevent misfires and makes removing easier in the future.

What is the benefit of iridium spark plugs?

Iridium Plugs improve the engine performance in terms of power. The extra power becomes apparent in situations like climbing hills, giving you a comfortable driving and touring experience. The ultra-fine center electrode of an Iridium Plug ensures fast ignition and improves the engine’s starting characteristics.

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.

Should I use anti seize on AC Delco spark plugs?

AC/Delco: Do not use any type of anti-seize compound on spark plug threads. Doing this will decrease the amount of friction between the threads. The result of the lowered friction is that when the spark plug is torqued to the proper specification, the spark plug is turned too far into the cylinder head.

How do I know if my spark plugs need changing?

Here are seven symptoms that let you know it’s time to replace your spark plugs.The car is hard to start. … The engine misfires. … The car gets poor fuel economy. … Rough engine idle. … Your car struggles to accelerate. … The engine is really loud. … Your ‘check engine’ light is on. … Frequency of replacing spark plugs.
