Hey guys, finally got off my ass yesterday and spent some serious wrench time on the 5.9. Here's what I did:
Comments:
- K&N FIPK
- M1 Intake
- Harland Sharp 1.7 Roller Rockers
- BBK Twin 52mm Throttle Body
- Mopar "Jeep" Cast Aluminum Valve Covers
- Silla Aluminum Radiator
Overview - Good look at K&N
Passenger Side - Good Look at Valve Cover, Intake, and TB
Driver's Side - Airbox and Custom Breather setup

Comments:
- I learned my Jeep is the perfect height that it strains my hamstrings to lean over the engine for any extended period of time. This is the first time in my life that my legs are sore from working on a vehicle.
- The M1 intake is an absolute work of art! Way better than that stock POS. They are darn near impossible to find these days, but if you have the opportunity to get your hands on one, GET IT! The engineering is what you'd expect from the group that designed the engine in the first place - no detail is overlooked.
- Roller rockers were way easier to install than I expected and made a bigger difference than I expected. Most unexpected difference - changed exhaust note. Definitely sounds throatier now!
- If you go with the Mopar Valve covers like I did, be prepared to fashion some sort of custom breather/PCV setup. I don't know if I was supposed to get grommets and shit with the covers, but I didn't. I got a regular chrome breather (3/4" neck) and a couple of universal 1.25" OD x 3/4" ID grommets from the local NAPA. Then, I had them look in the back for a PCV valve that fit into a 3/4" grommet and had a connection for a 3/8" hose. This seems to be working well so far.
Let me know what you guys think!
