Detailed Description

The Delphi GN10447 is an ignition coil for Porsche 911, Boxster, and Cayman applications that require a coil-on-plug design. It is engineered with Delphi’s OE heritage and manufacturing knowledge, bringing the same type of fit and electrical connection expected in factory-style ignition service. If you are replacing a weak coil on a Porsche 911, Boxster, or Cayman, the GN10447 supports consistent spark delivery and dependable ignition performance.

This part number, GN10447, is listed for 2001-2009 Porsche 911, 2003-2008 Porsche Boxster, 2006-2008 Porsche Cayman, and 2011-2012 Porsche 911 applications. It also cross-references Beck/Arnley 178-8425 and Standard Ignition UF-544 for the same application.

What It Helps Address

• Engine misfire caused by a failing ignition coil
• Rough idle during startup or at operating temperature
• Hard starting related to weak spark output
• Loss of power under acceleration from inconsistent ignition performance
• Check engine light conditions tied to ignition coil faults

Installation Notes and Tips

Verify the coil connector style, terminal count, and vehicle application before installation. The GN10447 uses a coil-on-plug layout with a 3-pin male terminal connection, so matching the original connector is important for proper fitment. Inspect the spark plug and surrounding ignition components during service to help prevent repeat coil failure.
