Yes, you do have 6 spark plugs! There should be 3 orange wire ends, that are probably the ones that you pulled off to remove the 3 spark plugs. Well the other 3 are undernieth of the coil packs. Which are the black packs right besides the other wires. Should be 3 of them. Sometimes they might be screwed down, or sometimes they can just be pulled straight up to remove. Just mark them all so you remember which hole they went in, otherwise you can end up with a misfire. Good luck. The coil packs arent screwed down althought it appears a small screw is installed. Just pull up on each side and wiggle it......just a little bit. Some of you might get that.
