Set of 2 NGK iridium spark plugs, providing reliable ignition performance. Purchased for a European car, used for approximately 20,000 km in a Fiat 500 TwinAir ABA31209. I was keeping these as spare parts, but I'm planning to sell them now that I've sold the vehicle. If anyone wants them, please take them. The gap is about 1mm. The box will be a substitute. - Brand: NGK - Model: LKR7AIX-P - Quantity: 2 - Condition: Good There are also used BOSCH spark plugs available.
