Basically it sounds very nice but im having a little light flash on my dashboard the signals a zig zag line lit up and a loose wire. We also took two wires out when taking out old part and putting in new filter and basically theres no where to put these back into with new filter so im kinda worried. Instructions said to tape em up out way. Are these not needed? Another side effect to this is my car is not starting up easy now. Sounds really dodgey :S And i never told my dad about this so im kinda worrying.
