If you are looking to dress up your 2003-2005 5.9 Cummins this is the first piece of the puzzle! Remove the cheap plastic valve cover / CCV filter and replace it with this sweet billet aluminum piece. It includes a billet oil fill cap and baffled CCV canister with AN type fittings along with braided stainless lines.
By removing the factory CCV filter you no longer need to purchase expensive filters when they get plugged and it also keeps crankcase pressures in check at high RPMs.
All parts including the oil fill cap are manufactured from solid 6061 T6 billet aluminum. Valve cover includes all stainless hardware and sealing surfaces are sealed with O-ring seals. The cover comes with a machined finish and is available polished.
THIS COVER WILL ONLY WORK WITH 2003-2005 5.9 CUMMINS. ALL 2006-2007.5 CUMMINS USE THE SAME COVER AS A 6.7 CUMMINS
