yes i heard that the fci does work with the stock air box, i think alot of people cut the back of the air box off to make the filter easier to fit and remove. its not really an option for me to import an fci, would be to much and take a while to get it here
today i cut both the holes out fit the rubber parts, just waiting on another air box to get the part off. should make a good increase in power, thanks for posting this
