Spark plug number order

Hello, I'm Danny.

Here is the information you requested. I've attached two pictures below showing the cylinder locations. Let us know if you have any further questions on this issue. Hope this helps and thanks for using 2CarPros.

Hi again,

I'm sorry to bother you, and didn't expect to. But, do you have a diagram of where to open up the area to get to the 1, 3, and 5 coils? I finally located them, but, it looks quite involved to get to them. I have crappy friends that promised to do this for me. They didn't show so, here I am and I can do this. I just need some correct guidance to avoid damaging something unintentionally. You are my hero, lol and thank you.

Hello again.

The engine cover should pop off easy enough to gain access to the ignition coils. Here is a YouTube video for a 2013 Optima which is similar.

WRONG ANSWER!! The plugs 1,3,5 are on the REAR and require ONE HOUR, at least, car knowledge experienced labor to remove that Intake Manifold!!
