Detailed Description

Hella 230035821 is an ignition coil designed for vehicles that require a bolted, flush-fitting pencil-style unit with a 3-pole connection. In Hyundai Santa Fe, Hyundai XG350, Hyundai XG300, and Kia Amanti applications, this coil supports reliable spark delivery to help maintain smooth combustion, stable engine response, and reduced emissions. The construction emphasizes mechanical stability, vibration resistance, and corrosion protection for long-term service in varied driving conditions. Part number 230035821 is also referenced by several aftermarket and OE-style cross numbers for the same application.

This part cross-references Standard Ignition UF-439 and NGK 48694 for the same application.

What It Helps Address

• Misfires caused by weak or inconsistent spark output
• Rough idle related to ignition coil wear
• Hard starting from degraded coil performance
• Loss of engine smoothness under load
• Corrosion-related electrical connection issues

Installation Notes and Tips

Confirm the coil style, bolted mounting, and 3-pin connector before ordering. Match the fitment notes exactly, since some Hyundai XG350 listings are marked as set applications. Inspect the coil boot, connector, and surrounding ignition components during replacement to avoid repeat failures.

Quality Assurance

HELLA tests this ignition coil for performance, mechanical stability, vibration resistance, and corrosion protection to support dependable operation over time.
