MSD 8.5mm Super Conductor spark plug wire sets feature a special helically wound core that has just 40-50 ohms of resistance per foot—but with an RFI suppression equal to a 1,500 ohm wire. In fact, each foot of finished wire includes 40 ft. of tightly wound copper for superior conductivity. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference "choke." This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. A tough, 8.5mm synthetic/silicone jacket over an extra-heavy glass braid and dielectric insulator keeps the current guided to the plugs. Underneath the high-temperature boots, dual crimp stainless steel terminals feature snap-locks to ensure a secure fit. Each set comes with clip-on cylinder markers for easy identification. MSD's 8.5mm Super Conductor wire sets are available in custom or universal-fit applications, assembled or not, with a variety of terminal and boot end options.

NGK V-Power spark plugs offer economical performance for nearly any automotive application—and they're the only plugs with NGK's V-Groove technology. These plugs enhance ignitability, lower the voltage requirements of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance. The V-Power plugs are also highly durable against electrical and chemical wear, making them long-life replacement plugs. Because of the V-Groove, the spark occurs at the edge of the center electrode—so heat is not absorbed by the electrode itself. This allows the flame kernel to expand quickly and efficiently for a complete burn and great performance. More than a hundred models are available, both universal and application-specific; order the plugs designed for fitment on your vehicle.

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.)
