Detailed Description

Delphi GN10335 is an ignition coil engineered for BMW vehicles that use a coil-on-plug ignition setup. Delphi draws on more than a century of OE experience and supplier knowledge from working with major automakers, and that background is reflected in the design and construction of this replacement part. If you are servicing a BMW 525i, BMW 740iL, or BMW M3 from the listed model years, this coil provides a direct-fit service solution for ignition maintenance.

This part number, GN10335, is also referenced by several aftermarket and OE cross numbers, including Bosch 0221504474 and Standard Ignition UF-226. That makes it easier to match the correct ignition coil when replacing a failed unit on select BMW 318i, 325is, or 540i models.

Common Issues This Part Can Address

• Engine misfire caused by a weak or failed ignition coil
• Rough idle during cold start or under load
• Hard starting related to inconsistent spark output
• Loss of power from intermittent ignition performance
• Check engine light conditions tied to ignition coil faults

Installation Notes and Tips

Verify connector style, terminal count, and engine application before installation. The GN10335 uses a 3-terminal blade connector, so the harness plug should match the coil design before service begins. Inspect the coil boot, surrounding wiring, and spark plug condition during replacement to help prevent repeat ignition faults.
