I INSTALLED MY CONE FILTER...AND MY ENGINE LIGHT CAME ON AS WELL AS MY TCS LIGHT??? CAN SOMEONE EXPLAIN TO ME WHY MY TCS LIGHT WOULD COME ON, I DON'T THINK MY IAF SENSOR SHOULD HAVE ANYTHING TO DO WITH THAT....ALSO I WAS TOLD BY A LOCAL MOTORSPORTS STORE THAT SINCE THE IAF SENSOR IS OFF..I GUESS THE AIR/FUEL RATIO IS OFF AS WELL, SO THE ENGINE IS RECEIVING MORE AIR THAN IT SHOULD AND THAT COULD EVENTUALLY FUCK UP MY ENGINE, IS THIS TRUE? ALSO DO I REALLY NEED TO GET A RESISTOR FOR THIS?? HELP...I just went to the local speedshop and asked for a 3'' open-end air filter they had 3 different kinds I got the middle priced one ($40.00) I dont have a part # but most company's have a universal filter,I know k&n does and it goes for around $60.00. Once you have your filter just pop the top off air box and I believe theres a couple on bolts you'll have to undo, throw the cone filter on, pull the IAF sensor out the air box cover and reattach it and just let it hang on the side. Your check engine light might come well actually it will so just disconnect the negative battery wire for a couple of minutes,connet it and start the car, if the light stays on then drive it around for a while and eventually it will go off. Hope this helps.
