BMW E46 323i/325i/328i (99-05) Mishimoto performance air intake black

The Mishimoto intake E46 is a performance air intake for the BMW E46 323i, 325i and 328i from 1999 to 2005. It replaces the original air box with a free-flowing system with an oiled air filter and a black powder-coated steel heat shield, and uses the stock air inlet duct for cool outside air.

The filter has 84 percent more filter surface area than the stock paper filter and a built-in velocity stack for crisper throttle response. The intake is safe to use with the stock tune and gives the six-cylinder a clearly sportier intake sound.
