How many coils do I need to buy?

These Max-Fire LS ignition coils are sold individually. You will need to purchase one coil for each cylinder your engine has. For example, a V8 engine will require eight coils.

What makes this coil better than my stock one?

This Edelbrock coil is designed to output up to 11% more voltage and 19% more energy than a factory coil. This means a stronger spark, which can lead to more efficient combustion, especially in modified engines.

Will this coil fit my specific LS engine?

This coil is designed for 1997-2013 GM Gen III and IV LS engines. However, GM used several different physical styles of LS coils. It's important to visually compare your existing coils to this unit to ensure a direct physical fit before purchasing.

Product Details

What you get here is a single Edelbrock Max-Fire LS ignition coil, designed to replace the stock coil-on-plug unit on a wide range of GM Gen III and IV LS engines from 1997 through 2013. This includes popular vehicles like the Chevrolet Corvette, Cadillac CTS, and Pontiac GTO. This coil is built to give your engine a stronger spark, which is especially helpful if you're running modified setups like superchargers, turbos, or E85 fuel.

Compared to a factory coil, this Edelbrock unit offers up to 11% more voltage and 19% more energy. It achieves this by using higher resistance, which helps maintain that strong energy output even at higher RPMs. The coil itself is sealed with high-temperature epoxy to handle vibration and heat, and the internal spark plug contact is stainless steel to resist corrosion. The boot is made from silicone and can handle temperatures up to 550 degrees F, so it's well-protected against engine bay heat.

Remember, these are sold individually, so you'll need to order one for each cylinder your engine has. It's a direct bolt-on replacement, but GM did use a few different styles of LS coils over the years, so it's a good idea to check that the physical shape of your current coils matches this one before ordering.
