Replacing plugs

[EGRIZZLE]

I'm at 105k and 8 years, the service manual calls for replacing the spark plugs really as the only big thing for this service. Have most on here done the same at that interval or at 8 years should I go ahead and do the 120k tune-up or just wait until then for the plugs as well?

If it's running fine wait, if you have concerns change them. or just go ahead and do both services now. Nobody ever regretted service too much or too soon.

Good time to do tranny flush, plugs and at the same time the fuel rail/injector cleaning. I also would look at brake lines; they are getting old!

I hope I'm not hijacking this thread, as I was ready to start another related one.

Our 2006 LR3 has just over 100K miles, and I've already replaced the spark plugs, which were just shot! In addition, three of the coil wires have gone bad, leading to poor performance (cylinders obviously missing).

Now, I'm wondering what kind of DIY job is it to replace the remaining coil wires, as the tech charges $110/Hr/coil wire, based on what I've seen on the last statement I received. I can research the cost of the wires themselves pretty easily.

HOUM,

I'm a bit confused about the tranny flush. I asked my tech about putting synthetic fluid in my tranny, and he didn't recommend it, saying that the manufacturer only recommends the 'standard' fluid. I didn't really press him on when to do a 'flush', but I'm not sure I have any way of actually knowing what the condition of the tranny really is, other than obvious symptoms. (I plan on using a Scan Guage II in the very near future, to at least monitor temperature.)
He also said that the newer trannys are 'sealed' and are not meant to be 'serviced' in the traditional sense. In fact, they don't even have a dipstick!

Fuel rail/injector cleaning; brake lines. Just a few more things to add to the growing list! Are there threads/videos on that DIY also?

Thanks for the input!

Use Genuine ZF Fluid or order from thectsc. Several manufacturers use ZF transmissions and several have their own fluids and various recommendations. I stuck with Genuine, Royal Purple for everything else.
