ITG Profilter - Performance Panel Filter Upgrade for BMW E46 3 Series 1998-2007

Give your E46 a breath of fresh air. This ITG Profilter is a direct-fit, high-flow panel filter that drops straight into the factory airbox, delivering freer breathing and crisp throttle response without compromising engine protection. Hand built in Britain and derived from top level racing, it is an easy, proven intake upgrade for everyday road use and spirited driving alike.
