The absolute worst one on a 98 expy to get to and replace. That's right number 3. The engineers that came up with this design should have to spend eternity changing these every day all day. Every heater hose setting on top of it. Plus that stupid power center. I did go ahead and Change the plug while it was at it.
I feel your pain. I had the same one fail 14 miles outside of Branson on our honeymoon this year, 200 miles from home. Luckily I found an O'Reillys and got it changed in the parking lot. It was expen$ive. I learned to keep spares on hand. Luckily I changed plugs last year.
I thought the #3 was a piece of cake compared to the #4. Not sure what made the #3 so tough?
I take a few bungees or rope and tie back the heater hose lines to get easier access to both 3 and 4.

I've changed out COP's on an F-250 V10 much easier, even though they set back further due to more space.

I've never seen that type of setup before. I guess the good old fashioned tried and true way of doing things isn't good enough anymore.
How do you know when one those goes out? I would imagine you'd get a real stumble or misfire.
