Just pulled a misfire on cyclinder 5. I am going to test the plugs first.

Does anyone have a diagram showing which cylinders are which ? I got some conflicting information on google.

If you have a V6, then right bank (passenger side in the US), front to rear goes cylinders 1-3-5. Left bank (driver's side in US), front to rear goes 2-4-6. So, cylinder #5 is the last plug on the right bank.

Ok thanks. I picked up one LFR5AIX-11 so I can check the cyclinder.
A. Am I right that these plugs come pre gapped to .043 which is what is needed for the v6?
B. What is torque setting? Is 18lbs right?

They are pre-gapped, but it doesn't hurt to double-check because you never know how much banging around the box did prior to you getting it. Yes, torque is 18 lb-ft.

Is there any way to upload those pictures again? I got a few plugs in but taking the intake off I can’t figure out all the steps. If anyone has the clear pictures I’d appreciate it.
For some reason the first post has all fuzzy pictures.
