Oil Filter Cap:
We've run into a LOT of trucks using incorrect oil filters. Incorrect oil filters do not close the bypass at the bottom of the oil filter canister, allowing dirty oil to bypass the filter all together. We ALWAYS recommend the use of ONLY original equipment Ford Motorcraft filters in the 6.0L Powerstroke, which is why we've included one in the Strictly Diesel 6.0L "Master Kit®". If you have been running one of the "non-Motorcraft" oil filters that came with a taller oil filter cap, you will need to reinstall the original factory cap in order to go back to Motorcraft filters. For those of you that don't have your factory cap, we've included an option to add one to this kit. We've also included the option to upgrade to the Bullet Proof Diesel billet aluminum oil filter cap.
