Yep. Just add with your next fill up. Gumout with regane is another good fuel system cleaner.

 

What's the best fuel cleaner

 

I use Lucas upper cylinder fuel additive with every oil change. Thankfully I'm nowhere near the mileage for spark plug change. And u can remove the coil pack without breaking it. It's the spark plugs that break.

 

I already listed the better fuel system cleaners. Techron or gumout with regane

 

I think he was asking what is better of the two

 

There both good. Oreillys as the gumout on sale right now.

 

Chaseman, from what I'm reading in this thread and based on my personal experience with my 06 I would say that if all your coil packs are firing properly, then at 90,000 or do miles you are probably due for a spark plug change. Recently I have been having problems with my truck sputtering, usually around 45 mph or so and at 1500 rpms going up hillbor taking an on-ramp. Took it in and even though I'm not getting a check engine light or codes thrown, the computer still records misses in your engine. Mine reported random misses in random cylinders which is the tell tell sign of bad plugs. Now from what I have read on the forum, these plugs are a son of a beach to get out in one piece. My dealer quoted me $140 for the updated 1 piece design plugs and $360 for the labor. Granted this is an estimate and could range quite a bit, just want to give you an idea of what you may be looking at. Now I got the champion plugs from NAPA for around $11 and some change per plug so saved some money there. That's with a small discount from a family member, but still purchasing them yourself you shouldn't be looking at much more than that which will be a significant savings over the dealer cost. I'll let you know what "my" mechanic quotes me for a change and get back to you. I will give details of the change ie how many broke etc and hrs of labor. Stay posted.

 

Thanks

 

Just an update, my mechanic quoted $150-200 assuming none broke. Soooo I decided to do them myself. I started by running seafoam through my gas tank about 5 days prior. Then seafoamed through the vacuum line the day of the change. I used PB Blaster to soak them for a few minutes before attempting to pull them out. Once I had sprayed them I put the socket with an extension on the old plugs and tapped them a few times, sprayed PB once more and then, the thing that seemed to help the most, I tightened each plug about an 1/8 or a 1/4 turn before loosening them. All 7 came out with ease all tho I was very careful and did my best not to put too much pressure. The reason I say 7 is because I had a coil and plug replaced just a couple months ago by the dealer. Hope this helps.

 

Just replaced my spark plugs on 2004 5.4 triton (115,000 miles) did everything your should do prior to removing. Used fuel cleaner in gas tank, removed at a "warm" operating temperature, spayed/soaked with kroil, went in back in forth motion, STILL 3 broke, and had to get special tool to remove the rest of the plug, this tool is definetly worth its money Lisle is the tool for the Ford triton. The kit says "broken spark plug removal tool for Ford Triton" shame on Ford for this stupid design, Lisle is making a profit on this tool for sure. Good luck
