A little advice...
If your CTD blows, as did a fellow's in my area, and you are found to have used (possibly documented by the dealer during a visit) or are using an unapproved filter, you can kiss your engine warranty good bye, as did the gentleman in my area. He was using a Fram on his engine. The darn thing was still hanging on it when the truck was towed in to the dealer. $4000. 00 plus bill for new engine! The minimal cost savings on filters just simply isn't worth the risk. Good luck!
