ZZPerformance High-Voltage Coil Packs

ZZPerformance offers high-voltage coil packs for a wide range of vehicles—including many Chevrolet, Cadillac, Pontiac, Buick, and Oldsmobile models from the early 1990s and up. The coil packs are available in different styles for various applications. Here are further details: * Model HVCP-14T: Upgrade your Volt/ELR ignition coil for improved performance and economy! The GM Voltec platform was designed around it's battery/hybrid system, but the internal combustion system was a budget solution—and the factory coil does not maximize the performance and efficiency of your engine. ZZP's high-voltage coil pack has improved core material, tighter coil winding, and higher voltage. No ECU calibration needed. * Model HVCP-38V2: These high-voltage coil packs will supply a stronger spark, which allows you to run a larger gap that will improve fuel economy, drivability, and HP capability. Not an earth-shattering difference but a small gain. Definitely well worth the upgrade if you're replacing your coils. --- Torque spec: 25 inch pounds --- No returns on electrical items. --- Sold in a set of 3. --- These fit GM 3800 W-Body and H-Body cars, including L67, L36, L32, and L26 * Model HVCPLSSQ8: After the resounding success of ZZP's round-style LSx ignition coils, ZZP now offers this square style. These coils produce on average 15 percent more spark—and have dyno-tested "before and after" results netting 4 to 5 whp gains on a naturally aspirated LS vehicle. Turbocharged and supercharged vehicles have netted 10+ whp gains and 15+ percent more spark than stock. Very impressive numbers for coils, better than OEM! This set of 8 coils will fit in place of the stock coils and connect directly to the factory connectors. Once installed, you'll have the power and performance of higher energy ignition. The increased spark energy and voltage help improve the combustion process of the fuel mixture to create a more efficient burn. This results in improved throttle response, smooth idle, and quick starts, plus increased high-RPM performance! The coil packs also work fine for totally factory/stock vehicles. Fits 4.8, 5.3, 6.0, 6.2 and 7.0L. (Note: There are many variations of LS coils even within the same make and model year, so please check your vehicle to see if you have the square style. These replacements will not fit vehicles with the round style coil. The connectors and the way they mount are different, so you have to verify they look like the ones pictured.)

Holley Universal Ignition Harnesses

If your vehicle's main wiring harness doesn't have COP (coil-on-plug) trigger wires, you can simply upgrade to one of Holley's universal ignition harnesses. They're specially designed to install coil-on-plug or coil-near-plug coils on Holley EFI systems into Holley Smart Coil ignition sub-harnesses or GM LSx coil harnesses. These harnesses are ideal for use with Holley HP or Dominator ECUs, but are compatible with other EFI systems, as well. Extra pins are provided for both the metripak and ECU ends, if you decide to shorten the harnesses. Caution should be taken to ensure coil trigger wires are installed in their correct pin locations to prevent engine misfire. Make certain your EFI system fires right every time with Holley universal ignition harnesses.
