My car is still under the original factory warranty and I am considering a chip. I am also looking into a CAI. The car is a 2003 325i. I know that chipping the car automatically voids the warranty but I remember reading about the shark injector (not sure) that can reset the car's computer to the default settings without the dealer ever knowing about it. I am not sure if getting a chip is worth it at this point. Has anyone else had this dilemma. Also I cannot decide if I want to get an ECIS, conforti, or cosmos CAI. I have read the reviews, but i cannot decide because no one has stated anything negative (that I know of) about any of the CAIs. The only drawback is the K&N filter in two of them but as long as its well oiled it shouldn't be a problem.
