Ignition Parts for Audi S4 Vehicles

Everything you do behind the wheel depends on spark. From the moment you turn the key or press the start button, to the instant you need a heavy dose of power, high-voltage current makes it all happen. Your car’s ignition generates your engine’s pulse, keeping it even and strong, whether you’re cruising Main Street or experiencing the G forces of track time in the ride you’ve painstakingly tuned.

USP Motorsports offers a generous array for choosing an ignition system or accessories, from original equipment to custom-engineered ignition upgrades that help to extract every ounce of power your engine can produce. Below you’ll find quality ignition parts from top brands: OEM Porsche, VW and Audi; and aftermarket suppliers Behr, Bosch, Denso, Integrated Engineering, NGK, Okada Projects, OKD and Torque Solution; and USP Motorsports assembled from multiple manufacturers...more

An ignition system carries battery current, which the coils convert into high-voltage current that your plugs use to create a spark each time a cylinder fires. An ignition component must be engineered to work with the model of engine in your car. All the ignition parts and systems we sell are designed to work with a specific engine, with its unique setup, so you know you’re getting a strong, reliable spark ­– especially important as you modify your engine to perform at higher revs.

Replace problematic factory ignition coil modules that have a tendency to fail, or upgrade with aftermarket coil modules engineered to deliver unparalleled performance. We’re experienced at making sure you get the right parts for your car.
