I have a 2011 Jaguar XJ that I'm about to change spark plugs on and I'm unsure how to get to #7 passenger side due to how tight it is. What do I remove? There's a fuse box in the way but not sure if I should mess with that if unnecessary. All forums I've read don't look like my engine, they seem to have more space than I do. Car only has 96k miles but it's struggling on start up and throwing p0300 codes, multiple misfires. Any advice would be appreciated as I'm doing this myself. I am mechanical savvy but I've never changed jaguar spark plugs.

 

Brandon, you may not like what I am about to say, but having been down your road and fought through "how in the hell do I do this", I finally got it done. The first thing that you are going to want to do is remove the cowl off of the car (the plastic cover that the windshield wipers go through, so yes, you need to remove the wipers from the car). This is going to expose 2 bars that run from under the cowl to the strut towers (you can see the torx bolts in your pictures on the strut towers). remove the 4 bolts for each bar holding it in place. then on the side with the #7 coil, you guessed it, you have to loosen the fuse box and then remove the shield surrounding the fuse box. Those two things will then open things up for you. I tried leaving the supports in place and it was just too much hassle. I would also say to disconnect the vacuum tube running across the top of the valve cover near #7. Get it out of your way so you don't accidentally break the tubing. yes it is extra work, but that was the only way I could figure out to get to that plug. Once you do it, you will see that it makes the whole process much easier to do.
