If your engine is hesitating or misfiring, it could be due to aged spark plugs that are past their service life. Did you know that as the spark plug fires it actually wears down the electrode increasing the spark plug gap? This is why old spark plugs often perform similarly to misgapped spark plugs. If you are experiencing poor performance and fuel economy, replace your spark plugs and restore performance.
NGK Laser Iridium spark plugs provide superior ignitability and long service life. Fine wire iridium tipped center electrode and fine wire platinum tipped ground electrode ensures slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions.
- Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
- Corrugated ribs prevent flashover
- Pure alumina silicate ceramic insulator, provides superior strength and better heat transfer
- Copper core aids in heat removal
- Triple seals prevent leakage
Maintaining your car at suggested service intervals will result in a better performance and improved fuel economy, which is why we suggest changing your spark plugs at the manufacturers suggested service intervals and be sure to check their condition for any warning signs of failure. If your vehicle isn't operating at peak performance it may be time to replace your spark plugs.
