GEN. 2 Top Mount Twin Turbo System

The On3 Performance GEN. 2 Top Mount Twin Turbo System is a comprehensive bolt-on turbocharger upgrade engineered specifically for 1996-2004 Mustang Cobra 2v and 4v 4.6L vehicles. This twin-turbo system is designed to provide significant power potential and includes a custom forward-facing header kit, stainless steel hot parts, dual 44mm wastegates, and dual 50mm blow-off valves. The installation of this kit requires a tubular K-member, A-arms, and a coil-over suspension system, such as those offered by UPR or Team Z, because the factory K-member does not provide the necessary clearance. Proper operation requires additional hardware, including an injector upgrade, a P-mas HPX MAF sensor, and a high-flow fuel pump, all of which must be sized according to your specific horsepower goals. To ensure complete functionality, supplementary components like a power steering reservoir relocation kit and a coolant crossover kit are required for installation. As this is not a universal kit, compatibility is limited to the specified 1996-2004 Mustang Cobra platforms, and professional tuning is essential to support the increased air and fuel requirements.
