Changing spark plugs on 06 SRT-8

I have never changed the spark plugs on my previously owned 06 SRT-8 since I bought it. I have put 85,000 miles on it. I can't find video on a step by step process or online manual for step by step process. Does anyone have anything I can use or I'm I getting over my head and should take to a mechanic. I know I have 16 spark plugs and OEM calls for NGK spark plugs. Any help would be appreciated. thank you

Absolutely no problem for a DIY.

Everything is right on top, the only hassle is 16 plugs.

So Steve could some look more worn than others? Or will the first one I take out and look at look like the last one I take out. I was thinking if I take out one and it looks good, the other should be simular and I can leave alone. I'm not having any problems but I know it well past due.

Just because one plug looks good, does not mean they will all look the same.

If you are going to check them, you should check them all. And if you are
already going to go thru the process of taking them out to check them, then
you should replace them.

You say your car is running fine now, but you will be surprised at how much
better it will run after you change the plugs.

Over time, the gap on the plugs gets wider due to wear, and will change how
efficiently the plugs can ignite the air fuel mixture.

Because its a gradual thing, you won't notice it as it happens. But over the
course of 85,000 miles, I bet the gap on your plugs is way out of spec now.

Also, changing them will give you better fuel economy and more power. It might
not be much, but its worth the cost of the plugs and a few hours of your time.

Do a search for "spark plug replacement" on this site. There are threads that have
plenty of pictures on how to do this. Most are for the 5.7 engine, but its virtually
the same for your 6.1.

Good luck!

Note that SRT8's ship with fancy NGK plat/iridium hybrids and are recommended replaced at 100k miles!

Not needed yet.

A good indicator is your gas millage. If you notice your mileage really getting bad a plug change may help you. 15K miles isn't far off the spec. I've had 100k mile plugs before & they seldom do last 100K miles before needing replacement.
However if you not having problems I'd leave them. Maybe buy now so you have them later.

You can't tell if the imbedded conductor is cracked, you can't tell if the insulator is cracked and it's hard to tell if the side electrode is in good condition (dielectric cracks or crazing) and at 85K, I'd seriously consider replacing them even though they are touted as 100K mile plugs. Fuel quality, intake contaminants and other factors are the real determining factor, not some engineer's expectation on life.

It's easy to do but it is tedious with 16 plugs.

When the spark plugs use a single or double platinum tips and they have a recommended service life of 100,000 miles for normal driving conditions per schedule A in this manual. The spark plugs have a recommended service life of 75,000 miles for severe driving conditions per schedule B in this manual. A thin platinum pad is welded to both or just the center electrode end(s) . Extreme care must be used to prevent spark plug cross threading, mis-gapping and ceramic insulator damage during plug removal and installation.

Spark Plug Removal:
1. Remove necessary air filter tubing at throttle body.
2. Prior to removing ignition coil, spray compressed air around coil base at cylinder head.
3. Prior to removing spark plug, spray compressed air into cylinder head opening. This will help prevent foreign material from entering combustion chamber.
4. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. Also check condition of ignition coil o-ring and replace as necessary.
5. Inspect spark plug condition.

Spark Plug Install:
Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged.

Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator.

1. Start the spark plug into the cylinder head by hand to avoid cross threading.
2. Tighten 5.7L spark plugs to 18 N∑m (13 ft. lbs.) torque. Tighten 6.1L spark plugs to 15-20 N∑m (11-15 ft. lbs.) torque.
3. Before installing ignition coil(s), check condition of coil o-ring and replace as necessary. To aid in coil installation, apply silicone to coil o-ring.
4. Install ignition coil(s).
