Standard Motor Products UF343 Ignition Coil for Mazda - 1.8L

The Standard Motor Products UF343 is a high-quality coil-on-plug ignition coil that converts low-voltage current to high-voltage energy delivered to the spark plug to ignite the air/fuel mixture within the cylinder. This coil-on-plug assembly performs the functions of both the ignition coil, which creates the spark energy, and the spark plug wire set that is designed to contain and deliver the high-voltage energy to the spark plug.

Premium Engineering and Manufacturing:

• Engineered and tested to meet or exceed OE standards for spark energy, impedance and durability
• Internal core made from grain-oriented electrical steel limits loss factor within magnetic circuit to reduce heat that may affect coil endurance
• External core made from oriented silicon steel for durability
• Neodymium magnet produces maximum high-voltage output at all speeds
• Advanced thermoplastics ensure proper connection and resist fractures caused by heat and thermal cycling
• High-temp boot prevents high-voltage leaks, while stainless steel spring with internal ferrite noise suppressor prevents radio frequency interference (RFI)
• Tin-plated brass terminals improve electrical contact and protect against corrosion

All Standard Motor Products ignition coils are expertly designed, engineered, and manufactured at SMP's IATF 16949-certified Poland facility, where each one undergoes rigorous examination and product validation, including extensive measurement and life testing, thermal shocks, thermal cycling, and vibration tests to ensure 100% product reliability. Each coil is designed to deliver improved durability and a longer service life.
