6.2 check engine light
Ok so I put a volant cold air kit on my 11' 6.2 and after I drove about 100 miles the check engine light came on.... Disconnected battery to reset the computer and it came back on after 100 miles or so.... Anyone have any problems with this kit and/or have any suggestions?

I had the same problem! Check every single connection. Might even take it off and put back together extra careful! Make sure all clamps are tight and leak free. Mine had a broken hose clamp then i had the tube too close to the throttlebody and it pulled the tube off at the airbox. Slowly but surely bud!
you might even have to get it tuned as i was still running a bit lean and had to richen up my fuel to +5

Yea I have been told that once it is tuned it will go off.... Just dont want to tune it till atleast after the first oil change... Guess I will put the stock box back on till I get 3000 miles
