I recently installed a K&N cold air intake on my truck so I will no longer be needing the stock set up. This comes with all screws and the stock filter. All you need is a mass airflow sensor and you are good to go. This air box and intake tube came off of a 2011 GMC Sierra with the 6.2l motor. Im not sure if it will fit the 5.3/4.8. Im asking $100 + shipping from Drayden, Maryland 20630 or if you are close enough to pick it up then $100.
