hey all, i was in contact with injen intake company and asked them about developing a cold air intake for the 5.0 r spec application and they said there research and development department was very interested in that market for our cars. the only thing is they need a test car in california to do some testing on. this is a great opportunity for someone to recieve a free intake for there car and to help the performance options for our cars. just contact injen and let them know.
