NGK 3106 spark plug for the 2003-2005 Mitsubishi Lancer 2.0L is a Laser Iridium plug that ignites the air-fuel mixture with a fine wire iridium alloy center electrode.
- Laser Iridium line, one of the NGK iridium spark plugs engineered for OE applications and tested for quality and durability
- Iridium alloy center electrode: iridium is 6x as dense as platinum and has an extremely high melting point
- Platinum tip on the ground electrode for ignitability and service life
- 98% pure copper core for heat dissipation, conductivity and ultra wide heat ranges
- Trivalent metal plating with anti-corrosion and anti-seizing properties for easy installation and removal
Hard starting, a rough idle or a misfire can mean the plugs are worn, though a weak ignition coil or a clogged fuel injector can be behind them too, so find the cause first. The engine takes four plugs, one per cylinder.
This plug is a direct-fit replacement for that car and engine.
