APR

<p>Founded in 1997 by automotive engineers Brett Augsburger and Stephen Hooks, APR has evolved from a pioneering ECU tuning specialist into a comprehensive performance engineering firm serving enthusiasts who demand precision from their European vehicles. The company specializes in aftermarket performance products for cars built by the Volkswagen Group, including Audi, Porsche, SEAT, Škoda and Volkswagen, operating from an 80,000 square foot facility in Opelika, Alabama.</p> <h3>Engineering Excellence Across Every System</h3> <p>APR's first product was an ECU software upgrade for the 1997 Audi A4 1.8T, but the company soon expanded its product line to include exhaust and turbo systems. Today, the brand offers a complete ecosystem of performance upgrades designed to work in harmony. Whether you're optimizing engine breathing with precision-engineered intake systems, upgrading to <a href="/10727-exhaust-system-kit-apr-1354">exhaust system kits</a> that balance flow and sound, or enhancing aesthetics with <a href="/1354-apr-tuned-exhaust-tail-pipe-tip-14907">exhaust tail pipe tips</a>, APR's products reflect decades of refinement on both street and track.</p> <p>The company's philosophy centers on measurable gains backed by rigorous testing. APR engine tuning products use proprietary software for reading and writing to Bosch Motronic engine control units, a capability that extends to hardware development as well. Components like <a href="/1354-apr-tuned-fuel-catch-can-51065">fuel catch cans</a> address the specific needs of direct-injection turbocharged engines, preventing oil vapor buildup that can compromise performance over time. Meanwhile, their <a href="/10214-direct-ignition-coil-apr-1354">direct ignition coils</a> deliver stronger spark energy for more complete combustion, especially critical in high-boost applications.</p> <h3>Purpose-Built Hardware and Wheels</h3> <p>APR develops and manufactures hardware, software, calibration & data-logging tools for engine and transmission controllers, including intakes, exhaust systems, intercoolers, turbocharger systems, suspension, brake systems, wheels, and more. Their <a href="/1354-apr-tuned-wheel-7644">wheels</a> exemplify this integrated approach—designed with OEM-plus fitment and constructed using flow-forming or forged techniques that reduce unsprung weight while maintaining strength for aggressive driving.</p> <h3>Why Enthusiasts Choose APR</h3> <p>APR was founded in 1997 with a corporate philosophy of Innovation, Integrity, and Excellence, principles that continue to guide product development. The brand's commitment to quality extends beyond the parts themselves to comprehensive customer support and a global network of authorized dealers. APR is highly complementary to the Dinan brand, which serves the BMW performance market, following its acquisition by Driven Performance Brands in 2017, positioning the company for continued innovation within the European performance aftermarket.</p> <p>For drivers seeking to extract more from their Volkswagen Group vehicles—whether through increased power, improved reliability, or refined driving dynamics—APR offers solutions grounded in engineering rather than marketing hype. Every component, from the smallest sensor to complete turbocharger systems, undergoes extensive validation to ensure it delivers consistent, repeatable performance under real-world conditions.</p>
