How many spark plugs does a Hellcat have?

I picked up a used 2015 Dodge Charger SRT Hellcat. I’d like to do some work on it myself, starting with a new set of spark plugs. How many spark plugs does a Hellcat engine have?

While most V8 engines have eight spark plugs, the Hellcat engine has 16 spark plugs—two per cylinder. That means if you want to swap in all new spark plugs, you’ll need to buy 16 for your Dodge Charger SRT.
It makes it a little more expensive to work on, but if you’re a driving enthusiast, it’s likely a price you’re happy to pay for 707 horsepower and a 4.1-second zero-to-60 time.
