Which coils are for cylinder two?
 

I am currently trying to swap my coils to see if rotor 2 coil is shot but i am not sure which coils are for rotor two? does anyone know of a diagram that shows which ones are for which cylinder?

Thanks.

It will be the rear coils closest to the engine

Radiator -> coil 1, 2, 3, 4 -> engine
Replace all of the coils, plug wires, and spark plugs, don't half ass it!

also you have rotors, not cylinders..

Thanks i found them. I replaced the two that were no good and the other two were in good shape. i would have replaced all 4 but they are expensive. got them from Mazda for 135$ each. I have new plugs,wires and 2 of the 4 coils.

And yes i know it has rotors i was thinking of what the OBD reader said. Cylinder 2 misfire so i had cylinders on my mind.

You could have bought all 4 from Advance Auto for what you paid for 1 from the dealer.

I'm glad I just got the two for now then lol. I needed them today so I didn't have much choice to look around and wait for shipping

$135 per coil seems a little expensive - Mazda USA themselves list them at $80.30 each and for example, Rosenthal Mazda in Arlington VA lists them at $64/each (obviously plus shipping and all that jazz).

If you're eligible for Mazdaspeed membership you'll get them even cheaper.

I bought them from the Mazda parts counter and it did seem a little much, wondering if he maybe charged me for a set for each coil. I'm glad i didn't get all 4, definitely going to look at some of the sites you guys recommended.

Appreciate all the help!

I don't know if there is an Advance Auto parts near you.
I use them for all my aftermarket parts.
I ordered my first set online about 3 years ago, picked them up at the store the next day.
I got all 4 for $125, and that was before I found out about the internet coupons that can yield substantial savings.
They come with a lifetime warranty, and at most places they will simply swap them for new ones if you tell them they are bad, theoretically getting free coils for life.
Personally, I wouldn't do it, but plenty of people do.
