What makes these NGK MOD ignition coils different from standard coils?

NGK's MOD coils feature custom primary and secondary windings designed to increase electrical output. They also utilize PET housings and premium epoxy resin for improved durability and insulation compared to standard OE coils.

Are these ignition coils compatible with any spark plugs?

NGK engineers these MOD ignition coils to perform optimally when paired with NGK Spark Plugs. While they may work with other brands, using NGK spark plugs is recommended for the best performance.

What does 'Not CARB approved' mean for this product?

This means the ignition coils do not meet the emissions standards set by the California Air Resources Board (CARB). As a result, they cannot be legally shipped to California.

Product Details

NGK is well-known for making reliable ignition components, and their MOD high-performance ignition coils are built with that reputation in mind. If you're looking to get the most out of your Audi A4, A8, S6, or RS6, these coils are a solid option. They feature custom primary and secondary windings that are designed to increase electrical output, which helps optimize your engine's performance.

These coils are built tough. They use PET housings, which are known for their strength, and are filled with premium, vacuum-sealed epoxy resin to ensure excellent dielectric strength and voltage insulation. The high-temperature silicone boots on the coil-on-plug (COP) connectors help keep out moisture and contaminants, adding to their overall durability. NGK even tests these coils under extreme conditions in their own ISO 17025 accredited lab, far beyond what a vehicle would normally experience, to make sure they hold up.

For best results, NGK recommends pairing these MOD coils with their own spark plugs. Keep in mind that these coils are not CARB approved and cannot be shipped to California.
