Why Choose K&N for your G 310?

The BMW G 310 series is celebrated for its agility and build quality. However, the stock intake is often a bit conservative. The BM-3117 helps "uncork" the intake path, allowing the engine to pull more cleanly through the gears. It also provides a slightly deeper, more refined intake sound that gives the small-displacement thumper a bit more character.
