Re-Stocking our shelves with our Milwaukee 8 55mm intake manifolds. On average, you can expect to boost your Harley’s performance by a remarkable 3-4% horsepower/torque by just bolting on our manifold. Pair our manifold with a simple tune and see 5-6% horsepower/torque gain. Add our CNC ported cylinder head package with the manifold and tune to see 12-14% horsepower/torque increase. A simple and affordable way to gain performance! 🇺🇸
