The Champion Spark Plug 7415 spark plug for the 1985 Honda Accord 1.6L / 1.8L and other vehicles ignites the air-fuel mixture in the combustion chamber, with platinum on both the center and ground electrodes.
- Part of the Champion Double Platinum Power line, with exclusive Heat-Active alloy
- Dual platinum construction resists wear and electrode erosion under high-heat, high-load conditions
- Built to meet OE fit, form and function
- Fine-wire center electrode ignites faster and more efficiently, for dependable starts in all weather
- Platinum-enhanced ground electrode aims the spark precisely for optimal combustion
- Its alloy quickly reaches and holds the correct operating temperature under all engine loads, for reduced fouling
Worn spark plugs can bring hard starting, misfires or a rough idle. A weak ignition coil, cracked plug wires, a worn distributor cap and rotor or a vacuum leak can produce those symptoms too, so track down the cause before you buy new plugs.
The 1973-1987 Honda Civic 1.2L / 1.3L / 1.5L and the 1989-1998 Hyundai Sonata 2.0L / 2.4L each take four of these plugs, and the plug also fits many other cars, trucks, motorcycles and snowmobiles, where the count varies by engine.
