I would leave it alone. I Used to put lower ristrction mufflers on, remove resonators etc on cars I owned in the past. Its always a comprimise and will probably leave you with negative side effects. Several of you flamed me on putting irridium spark plugs in, those same engineers tuned the engine to operate with the back pressure and flow from the factory set up.
My 2 cents,

Crappy Tire lol

I have the Michelin blades from Cosco Canada as well. I have been using them on my Caravans and find they last about 2 years for me..

Thanks for the input I will try them and see.I have had good luck with double platinum in my 3.3 Caravans and older 2.2 and 2.5 shadows.

The 3.7 in my Nitro also called for copper plug changes every 30,000 miles. The reason for this: the heat at which the copper plugs burn to keep carbon deposits from forming in the plastic intake manifold. May be the same thing in the 2.4. If the engine calls for copper plugs, that is what I would use. It may run fine now with the iridium plugs, but you are only asking for trouble down the line.

Copper plugs are about 1/3rd the cost of platinum or iridium plugs, but only last about 1/3rd as long. If you're changing the plugs on your own (and for this engine, unless you are REALLY bad at turning a wrench, you should be), the only difference is the 20 minutes every 30,000 miles it should take to change them out.
Also, by using "not what is listed as an OEM part," you run afoul of the powertrain warranty and any future issues with engine performance or emissions can be blamed on a non-factory-approved part to void a warranty claim.
Many engineers spent substantial amounts of time determining what the best spark plug is for this (and any other) engine. Unless your level of education in engineering exceeds theirs, it's probably best to stick with what they recommend. Or do what you want, it's your car.

Believe me. Stick with copper core and change every 30k. The 2.4 in our 09 ran like a top for 80,000 miles.

No carbon tracks that I could see. I think the air filter and plugs were the originals. Really like the way this runs and drives now. When the weather clears I want to check out the battery to see what supprises wait for me there.
Hank

Earlier today I decided to take a look at the spark plugs and air filter and for any vacuum leaks. I found worn out plugs and a dirty filter. This car only has 80,000kms. I installed 4 new ngk irridium plugs and a new air filter, runs so much better now and generally smoother.
Hank

Thanks for your quick answer. That is the panel that I was referring to. A well placed bolt or two will be in my future.

Did not see it posted it here so thought I'd post it. Hopefully not a against the rules.

I use a bluetooth mirror that clamps onto my existing mirror.

Judging by the images from their website, it won't work for the Journey. The pinch weld for us is nearly 1" in height. That adapter looks like it's only 1/2" deep maybe. It also only serves for lifting, not something that can be used with jack stands. I'll get photos over the weekend of what I'm making - no one has voiced any safety concernes over the use of vulcanized rubber, and there are several products on the market of similar material. I'm just going to make my own for a total cost of materials of $8 (and an as-yet undetermined amount of time with a hack saw).

Thanks for the big welcome! I am looking forward to interacting on here. The 7 Chrysler minivans we have owned up to now treated us very well.

My wife and I just purchased a 2013 Journey and pick it up tomorrow.
