Anyone running the spectra cone filters on there cummins? Just wondering. I used to run them on my gasser cars without any problems but figured they probably aren't the best for our motors. My buddy was saying they can dust the turbos but I wasn't sure if he was just being overly cautious.

I've also heard that there isn't any difference in the stock air box unless you get into the 450hp range.

Just curious because they used to make a helluva difference on my gassers with the increased airflow.
