For the NC we’ve taking a method of all inclusive, this includes the intake system. We’ve designed a cold air box that is charged through a K&N cone filter and fits back into the factory bumper providing a cold dense charge. Post filter the box hold the correct volume of air to provide crisp throttle response. The MAF bung is welded into the charge tube. Everything you need from the throttle body out. No cutting of the front core support and works with factory hood latch. 6061 Aluminum construction tig welded with a cleanable/reusable fitler.
