Seen this on other websites, so figured I'd start it here. Please reply with additions you find and I'll populate the thread with a final list of aftermarket upgrades. I'll track by major component categories for ease of viewing. I will attempt to omit sellers so you will have to find these online on your own. That way i don't send customers to one vender and not another. Also, the items are presented in no particular order other than how quickly they appeared when searched - and right now I'd like to post REAL products vice items "in the works".

Let's get started:

Visual / exterior upgrades:

SRT-style or related aftermarket hood:
Pros: Look/style; heat extraction; lighter than stock
Cons: Most hoods require slight modification (relocation of coolant expansion tank) for use on a diesel model; possible water ingestion into engine bay

Suspension upgrades.

Adjustable Air Ride Leveling Kit:

Miscellaneous upgrades:

DEF injector protector plate:
Pros: Protect vulnerable DEF injector and wiring
Cons: none?


DEF line protector
Pros: Protects DEF line down the length of vehicle; works in conjunction with the DEF plate (above)
Cons: Some modifications needed to plate with certain accessories (rock rails) making installation difficult


Oil Separator (AKA "catch can"):
Pros: Keeps oil residue out of intake tract (turbo, intercooler, etc.); reduce sludge build-up (oil + EGR = goop that will need to be chiseled out)
Cons: Possible engine code thrown if not made to spec (currently there no agreed upon specs); right now nothing commercially made specifically for Jeep GC diesel
Notes: In my previous cars, I've always looked for cans that can be cleaned easily, are completely sealed (inspections violation if not), simple to mount, have an internal mesh or media to help swirl or filter the oily vapors, and have an external visual indicator of how full the thing is. Example below, but would need bigger inlet/outlet tubes:


Additional protection "bash" plates:
Pros: Stock under engine tray is extremely vulnerable and can be torn or collapse upon impact since it is made out of a weak and flexible material; adding other components completes the full under-body protection from tip-to-tip (Lower guard + Sump guard + Tranny guard) and protects the vulnerable gaps in the stock setup
Cons: Expensive to ship from overseas distributor and long shipping times

Nothing official on the sound or volume of any of the exhausts so far (like a "before and after" comparison) since the market for the exhausts are pretty small and the Jeep GC Eco-diesels are few in number. However, the consensus is that the DPF and the cat kill most of the exhaust sound in general that even straight pipes would still be pretty quiet or at least near stock level. Pretty small hp/tq increase for the same reason. Plus you run the risk of drone which is killed by the stock mufflers. Maybe the market will open up a bit in 2015 and more owners and manufacturers will upload clips for comparison.

I think the only two oils that fit the specific requirements (Chrysler spec MS-11106) for this engine are Pennzoil Ultra Euro L (factory fill) and Mobile 1 ESP (slightly better), both 5W-30. Currently MS-11106 is one of the most restrictive requirements for oil right now, and while there might be a few other alternatives if those two oils are unavailable, it really isn't worth it in case the engine has any warranty issues. Stick to those two.
 
#18 ·
LOL, yes, funny name, except it is called "Liqui Moly" not Liquid Moly. Also, it does not comply with MS-11106, so rolling the dice. In fact, if you want to go the expensive route, a competitor (and better option) is the Motul product line. That is some great oil. But again, no MS-11106...
 
#19 ·
Son of a ..... Now I have to go out and find a new oil. I'm going to feel like I'm cheating on a German Porn Star with a name (turns out) I never really knew quite correctly! Thanks hayasa! Thanks a lot! So, now that my dreams are shattered, what oil DOES meet all the specs? I'd think AMSOIL would have something, but I haven't seen it. Don't believe Royal Purple has anything. I personally hate Penzoil (for no good reason whatsoever).
 
#21 ·
Before anyone suggests that it doesn't. Mobile 1 ESP 5W-30 DOES meet the spec.
https://mobiloil.com/en/motor-oils/mobil-1/mobil-1-esp
Mobil 1 ESP Formula 5W-30 has the following builder approvals:
  • BMW Longlife 04
  • MB-Approval 229.31
  • MB-Approval 229.51
  • Volkswagen (Gasoline/Diesel) 504 00/507 00
  • Porsche C30
  • Chrysler MS-11106
  • Peugeot/Citroën Automobiles B71 2290/B71 2297
  • AVTOVAZ LADA cars

Mobil 1 ESP Formula 5W-30 meets or exceeds the requirements of:
  • ACEA C2, C3
  • API (Meets Engine Test Requirements) SM/SN
  • JASO DL-1
  • AAE (STO 003) Group B6

Technically, a dealer *can* deny your warranty for anything - and this attitude varies across dealer shops. The question is, is it worth fighting it? The law generally says that if you mod something, anything "down stream" that is affected by your mod might be subject to a dealer denying the warranty on those items. In many case, the law is on your side (for instance, if they deny your warranty to your Uconnect after you add an exhaust - the two are not connected and the modification of one doesn't affect the other. Law says they cannot do that. But you might have to take them to court to prove it.) The big thing with aftermarket intakes is 1. That is the FIRST thing they see when they pop the hood - and it starts off the warranty negotiations on the wrong foot, and 2. Modding the first component of the entire engine system technically puts everything else behind it at risk. Say the intake is an extremely low quality version (or is not installed properly) and lets in all sorts of dirt particles, which grenades the turbo, sending bits and pieces into the engine. That engine is toast - and you prob will not be able to get it fixed under warranty. They will fix it, but you will have to foot the bill. So in many cases, a decent manufacturer offers their own warranty to supplement the potential loss of warranty by installing their part.

First, I thank you, Hayasa, for putting this list together. I've just traded in my Wrangler for an diesel Summit, and I'm looking forward to playing with it.

Second, a bit of clarification. There is no statutory law (law written as out by a government entity) regarding specifically the implementation of a warranty in a modified car. The only statutory law that applies is standard contract law. There is substantial case law (the results of cases that implies the interpretation and application of statutory law) to indicate that a manufacturer cannot void a warranty, unless they can substantially prove that a specific modification contributed to a specific defect/failure. That said, you are completely correct in suggesting that the only way to enforce this would be to take a dealer to court after they denied you service under your warranty contract.

By the way - the above would apply for oil as well. And I think it would be extremely difficult for a dealer to prove what brand of oil you have in your engine. Anyway, Mobil does now list the MS-11106 builder approval on their website. I think that's as good as having it on the box, but I'm sure there's a Tommy Boy joke to be made here...

has anyone confirmed if using these plug-in "power adders" that the information is stored by the vehicles computer even after the "power adders" has been removed?

This is some literature regarding these in the owners manual/diesel supplement

NOTE: Some aftermarket products may cause severe
engine/transmission and/or exhaust system damage.
Your vehicle’s Powertrain Control Systems can detect
and store information about vehicle modifications that
increase horsepower and torque output such as whether
or not performance-enhancing powertrain components,
commonly referred to as downloaders, power boxes, or
performance chips have been used.
This information cannot be erased and will stay in the
system’s memory even if the modification is removed.
This information can be retrieved by FCA US LLC, and
service and repair facilities, when servicing your vehicle.
This information may be used to determine if repair will
be covered by New Vehicle Limited Warranty.
