Show original supplier description
The Precision Raceworks BMW N54 Replacement Coil Power Harnesses are designed as direct replacements for your N54 engine's ignition coil power wires. Each pack contains six wires, crafted with low-resistance, oxygen-free copper for optimal performance. These harnesses are 100% custom-designed and utilize injection-molded coil connectors, a unique offering from Precision Raceworks, engineered to meet or exceed OEM specifications. The components used in these harnesses are built to last, featuring seals that provide resistance against both dust and water ingress. This ensures reliable performance in various conditions. The pack of six allows you to replace all necessary wires or keep spares for future needs. It is important to note that these harnesses are NOT compatible with B58 coils. They are designed to fit specific BMW N54 engine models including the 135i (2007-2010), 1M (2011), 335i (2006-2010), 335i Xdrive (2009-2010), 335is (2011-2013), 335xi (2007-2008), 535i (2008-2017), 535i Xdrive (2009-2010), 740i (2011-2012), 740li (2011-2012), X6 (2008-2009), and Z4 (2009-2014).
