What is the secret to replacing spark plugs on the passenger side of engine block?

I have done a search on the subject and the threads I found centered around reasons for and against changing them before the recommendation in the owners manual. What I can't find is how in the wide, wide, world of sports you could ever get to the plugs on the passenger side of the engine block, especially a lifted JK. First off there appears to be a wall between the battery tray and the block. Next there is what I think is a radiator return hose running almost on top of the plugs. Add a coupla inches of lift and I'm in over my ski's.

Has anyone successfully replaced them and lived to tell about it? Maybe there is an obvious solution, which is why I didn't figure it out...any ideas?

 

I changed mine when I did my headers I had the battery box out so it was a breeze. I think you can get at them if you take the fender and liner out. I'll find out this weekend when I take the fender off to try and retighten my headers

 

I did all six of mine in under thirty minutes. There's actually nuthin to it.

 

Same here...i mean how hard can you really make it?

All you need is a swivel/universal extension and a few 3" extensions. I also used a 1" extension for a better angle.

 

My tip on changing the plugs is to place the hood all the way back on the windshield so you can get in there....made it a lot easier for me. Also, passenger rear is the worst, yet drivers side is a breeze. I thought it was easiest to pull the plug wire support bracket and vacuum line support bracket off the valve cover studs - they just slide off - gave more access to the rear plug and took 1 min to remove and replace. I did use a torque wrench at 15lbs to prevent overtightening.

Not too hard, swivels and extensions help.

 

I didn't use an extension at all on the passenger side. All I used was a 3/8" long handle ratchet and a SnapOn universal spark plug socket. You need the extension on the driver side. Actually the hardest thing about the job is opening the hood.

 

A few universals and a mix and match of extensions and voila! Done in no time! Don't forget to NOT over tighten and use a dab of anti-sieze

 

I wanna why you guys are all changing your plugs? Going to different temp plugs for turbo/supercharger or different comp tune? If it is still a stock motor, sis different plugs change anything?

 

I chose to change to the E3 diamonds because I wanted to smooth out my idle and, if I got any performance gains, then cool. There are lots of posts about Bosch, E3s, etc., if you care to look for them to see the varied opinions.

In my case, I got the smoother idle AND improved throttle response - particularly in the acceleration band of up to about 45 to 50 mph. YMMV.

Not bad in my opinion for a under $40 investment.

 

... I can open hoods all day.
