Show original supplier description
The Mazda ignition coil, part number N3H1-18-100C, is a Genuine Mazda component engineered as the latest specification replacement for all RX-8 models. These updated coil packs are crucial for ensuring proper spark plug function and preventing potential engine failures often associated with mileage over 30,000 miles. It is important to note that many aftermarket or fake coils are available and can cause operational issues or damage to the RX-8 engine, which Racing Beat Europe explicitly avoids selling. Sourced directly from Mazda Japan, these ignition coils are designed as direct replacements for the original equipment. The product listing replaces multiple previous part numbers including n3h118100, n3h1181009u, n3h118100a, n3h118100a9u, n3h118100b, and n3h118100c. There are four individual coils fitted to the engine, and this product is sold as a set. These coils are confirmed to fit all RX-8 variants, including the 192, 231, R3, and 250 models. Racing Beat Europe emphasizes that using non-genuine ignition coils can lead to the coils not powering the spark plugs correctly, which has unfortunately been the cause of engine failures in some RX-8s. The company ensures that all coils sold are authentic Mazda parts to maintain engine integrity and performance.
