High Voltage Coil Packs

The ZZP 3800 High Voltage Coil Packs feature improved core material, tighter coil winding, and higher voltage output to provide a stronger spark. This enhanced spark allows for a larger spark plug gap, which can lead to improvements in fuel economy, drivability, and overall horsepower capability. While not an earth-shattering difference, it's considered a worthwhile upgrade, especially when replacing worn-out coils. These coil packs are engineered for specific GM 3800 engines, fitting W-Body and H-Body cars equipped with L67, L36, L32, and L26 engine codes. They are sold in a set of three and come with a limited lifetime warranty. The recommended torque spec for installation is 25 inch-pounds. It is important to note that all electrical items are final sale and cannot be returned. No ECU calibration is required for installation, making it a straightforward upgrade. However, these specific coil packs are designed for the 3800 engines and are not compatible with other engine types, such as the 1.4T engines found in some Chevrolet Cruze models or the LSX engines. Always verify compatibility before purchasing to ensure proper fitment for your vehicle.
