just left my local dodge dealer,,went by to look at the 2003 1 ton... one of my friends was there having his dodge checked for something and the service writer told him while i was there that K&N filters were causing some engine failures and that cummins nor dodge nor K&N were standing behind ANY repairs... the writer also showed my friend and me a service bulletin that warned against having Pennzoil or any other brand oil filter other than Mopar, that it would void the warranty if there were a problem... also mentioned was using only Mopar fuel filters..... CAN THIS BE ACCURATE???????????
