Not sure where to put this but I need to do plugs on my 16 rebel. I changed mine on my 13 but can’t remember paying the $400 dollars from the dealer for just plugs when I can get ngk from parts store for $100. Do I need dealer plugs? Thoughts?

I’m seeing mopar plugs on eBay for $81 for 16 or ngk plugs online for $59 for 16. Either is a safe bet.

The guy at dodge said it wouldn’t run with copper ones? I don’t know if he is feeding me a bunch of BS

The oem plugs are manufactured by ngk and they are iridium. https://www.amazon.com/Chrysler-Dodge-Liter-Spark-Mopar/dp/B00LME0BQQ $73. I thought $400 was a high installed price. If you are paying that just for parts I’m in the wrong business.

You can't use copper plugs. Need to be iridium. Good luck. It's an easy job.

Yes, and if you go back 10 years chrysler sold 5.7L hemi’s with copper plugs anyway. The service life was only 30k which is why they went to iridium. Saying you can’t run copper is factually inaccurate, but at less than 30% of the life I wouldn’t.

Yes you are in the wrong business. It’s $26 bucks a plug here in Canada

Canadians can’t order from the internet? I wouldn’t pay $26 for a spark when you can get all 16 for under $100. To each his own I guess.

Lol. The dealers want $26 a plug here I ordered some off line

Those are NGK LZFR5C-11 which are copper plugs. The iridium analog of them is NGK LZFR5CI-11: Best Spark Plugs for 5.7 HEMI: How to Choose the Proper Ones. The set of 16 costs about $120

Regarding materials, you can install run copper plugs no problem up to 30k miles, but iridium plugs live almost 3 times longer. Thus buying a set of iridium spark plugs is a much more cost-effective solution
