Finally took off the CAI from my truck (5.4L) last night. Went back to the stock intake system, so I have no use for it. Not sure how many miles are on it. I bought my truck at 109k and I have 114k on it now. Previous owner put it on. K&N 57-2556 - K&N 57 Series FIPK Air Intakes - Overview - SummitRacing.com Comes with everything you need (brackets, filter, hoses, etc.). Previous owner painted it blue, but he left a sweet Summit sticker on it (adds 5hp I'd say). I don't know much about K&N filters, so I don't know if it needs to be "recharged". Not sure on price since it's used. $150 obo + shipping.
