Well I've been reading up on changing spark plugs and some people say it's insanely hard and others say it's very easy. The people who claim it's easy, I noticed, have body lifts, allowing for easier access to the spark plugs from underneath. I am wondering, is there anyone who's changed there spark plugs quite successfully without a Body lift?? I am planning on changing them but if it's uber hard I'll just leave them. I have an 03 FX4 4.0 if that matters.

 

pull your inner fenders and make sure you got a universal attachment for your ratchet and be sure to have multiple lengths of extentions.

 

I have a lowered truck and have done it twice now. The ones that are gonna give you the most trouble are closest to the firewall. Take off both wheels and pass side fw, made a lot more room, to get at it. I didnt use an ext. on #3, you can get right up in there if you remove the fw and just use a swivel. The same for the driver side, no ext. on closest to fw. I have JBA headers which made changing the plugs a major PITA cause of the thick flange. The last time I changed out the plugs I did it like this in an hour. Change `em out with your truck ice cold and thread `em back in with your fingers first and you shouldnt have any trouble.
Edit: I did the first two on the drivers side from the top, the third from the ww.

 

My buddy pulled his wheel and inner fender off to get at them, but it made it a million times easier than it would've been.

 

there not insanely hard just need to be creative

 

Pop a few oxycodones, snap your lower arm in two places, and it will be very easy.

 

i changed my plugs and wires in less than 20 minutes with no knuckle banging. Ive got a 2001 3.0.

Basically all i needed was an extension for my ratchet. If you know what you are doing should be easy i suppose.

 

i lay on my stomic on top of the motor to get the farthest one in the back passenger side all the other ones are easy

 

Pull the tires and inner fenders. Makes it so much easier. 1st time I didn't and it was a royal PITA, 2nd time I did, and it was a lot easier. Also becareful of the middle plug on the passenger side. Its quite tricky putting it back in. Just take your time so you don't cross thread it (well that goes for all of them).
