Spark Plugs

I read the my 2016 Patriot owners manual and read plugs should be replaced at 30k miles. Is there a longer lasting Platinum plug that people are running that will go longer?

A patriot comes with copper plugs. copper plugs should be replaced at about 30k miles. You can put in a platinum (70k miles) or iridium (100k miles), but your engine was designed to run on copper plugs. They take like 5 minutes to change out, and unless you drive a ton of miles, that's 5 minutes every 2-3 years... and the cost is negligible.

I've put longer running plugs in my other cars that require a half a day to replace them, or half an engine disassembly. but on an inline 4? where they are right there on top, and all you have to do is remove that plastic cover? I would stick with copper personally, and change them ever 30K miles.

I bought Champion double-platinums for $25(for 4 of them), and they've lasted quite a bit. They also are cheaper per mile, as I understand it. Granted, that's roughly $15 for coppers vs $25 for an upgrade, and something you only do once every few years. But every little bit helps, right? Besides, it's a fun way to do a mildly unusual mod that might(I'm hardly an expert) make the engine spark a little cleaner.

You should only install what the OE recommends. If you put in the fancy doo dad unobtanium plugs you might end up with miss fire codes in the computer because of a change in the ignition "coil soak".

In some engines that is definitely the case (the old Jeep 4.0L I6 is famous for running like crap on anything but copper), but I haven't seen anything to indicate this is an issue on the GEMA world engine (most modern engines, especially those with coil on plug ignition have no issues with platinum/iridium plugs) and since the 2 other automakers (Hyundai and Mitsubishi) using variants of that engine used iridium from the factory it is likely that Chrysler's use of copper was likely more of a cost saving measure than anything else. As others said changing the plugs on a Patriot is easy enough that there isn't any real reason to use longer life plugs (unless you're paying someone to do it then the labor savings would add up quick, or just don't like changing plugs), but they are unlikely to cause any issues either.

Time is money for me ... well that is when I have the time lol!
I save time and money by putting iridiums in once every 100,000 miles.

under the hood on the hood itself is a label with Plug #
putting any other plug in could void your engine warranty

Thats a pants on fire lie!
Replacing your spark plug with any other aftermarket plug that is spec'd for your Jeep will not void any warranty.

Ditto! Once you define the correct tools, it takes less than 15 minutes--which allows for hand cleaner, etc.

i dunno, takes me at least 30 minutes. you have to:

1) get tools ready-
magnetic socjket and ratchet with extensions to emove plugs
tx-bit to remove the hold down for the coils
torque wrench
dialextic grease for boots

2)yank the cover off

3)gap the plugs

4)unbolt the coils

5) remove a coil.

6) unscrew a plug

7) insert new plug and torque to 20 ft/lbs

8) repeat steps 3-7 for the other 3.

9)reconnect the coils and bolt down.

10) replace engine cover.

point is, it takes way way more than 5 minutes..LOL..

I just put Bosch Platinum in mine about a month ago. I went to get new spark plugs and Advance auto parts had the bosch platinum plugs on sale for what the copper plugs cost. So, I figured I would try it out. No messages or codes (other GEMA engines are using platinum or iridium from factory), runs fine, no increase in MPG or performance. Nothing magical happening here.
Use whatever spark plugs you want that are listed as compatible for your engine.
Will the platinum plugs last longer than the copper plugs? I guess I'll find out....
