Kooks Headers and Exhaust has been a leader in high-performance exhaust solutions for over 50 years, providing components that meet the rigorous demands of racing and street applications.
This specific 12-inch O2 extension harness is engineered for a perfect fit on several iconic GM performance vehicles. It is compatible with 2004-2007 Cadillac CTS-V models, all 2008-2009 Pontiac G8 trims (Base, GT, GXP), and 2004-2006 Pontiac GTOs. The harness features OEM-style connectors for a direct, plug-and-play installation, eliminating the need for complex wiring modifications. Trust Kooks for reliable, high-quality wiring solutions that complement your performance exhaust system, available at GGCRACING.
