NGK 7067 spark plug for the 2006-2020 Yamaha SJ700 Super Jet and other vehicles ignites the fuel charge with a fine-wire iridium center electrode. It is one of the NGK iridium spark plugs in the Iridium IX line, made for modified or high performance applications and as an upgrade to OE nickel alloy spark plugs.
- Fine wire 0.6 mm iridium tip center electrode for durability and a consistently stable spark
- Iridium alloy center electrode with a density six times that of platinum and a very high melting point
- Tapered cut ground electrode with a reduced quenching design for ignitability, acceleration and fuel efficiency
- Solid copper core, 98% pure, for heat dissipation, conductivity and wide heat ranges
- Trivalent metal plating with anti-corrosion and anti-seizing properties for easier installation and removal
Quick facts
- Part: NGK 7067 spark plug
- Fits: 2006-2020 Yamaha SJ700 Super Jet and other vehicles
- Condition: New
A worn plug can show up as misfires, hard starting or weak throttle response. Those signs alone do not prove the plug is the problem, since a tired ignition coil is another common source.
