i have the airaid system (just a filter and new airbox lid). i installed it about 12 hours after we drove the thing home from the dealer. it now has about 500 miles on it and nothing to date. i am looking at getting a air intake tube to go from the box to the throttle body. i don't know if that has anymore effect on it. are the two tubes that go to the intake tube connected?
