hey i just got a 1999 cobra with 11,000 miles on it and i want to put in an Jlt intake. i wasnt sure with to go with the RAI or CAI. Im also afraid of suckin up water with the cold air,and i live in new jersey so theres not any crazy rain or anything. I also want to if its worth it to spend the extra cash on the CAI, cause im also saving up for an full exaust system. And is it a must to get a tuner if i get one of these intakes?
