I just did this eager to see the results and right after my valve cover gasket blew and started smoking....now I have to wait 2 days before I get to see the results. I'll be back with an EDIT and leave my review. Anyways it was easy enough. Only took 20 minutes or less. I only had 120 grit so I had to work with that just make sure you have all the masses of the charcoal filter out. I washed the box after then cleaned the MAF. That's all for now, I'll post the aftermath next week. Oh and be careful the filter is dirty as hell and when you rip it out, you might accidentally breathe in the dust and yea....watch out.
