In the coming spring I (will have 55-60K miles on it) am planning to replace the plugs and wires. The truck will be 3 years old and I figure waiting for 100K is asking for trouble. Will put platinum splitfire plugs in with splitfire wires. Also going to put the hard wire protectrors on all the spark plug wires to protect them from heat.

I just checked my platinum tipped spark plugs that have 55,000 miles on them...major carbon build up. I figured I could wire wheel them clean but I went ahead and replaced them anyway.
As far as belts go, I replaced my serpentine belt at 60,000 miles due to cracking. Now at 120,000 miles that belt is also showing cracks in the rubber. I guess now I have two spare belts. The salesman who sold me my truck told me how that belt will go 100,000 miles...Ha!
I have yet to replace wires. I do go through a lot of caps and rotors though..about every 10,000 miles my mileage drops 2-3 miles per gallon and goes right back up after a new cap and rotor..

My '93 diesel went through belts in the first 500 miles until we correctly reshimed the alternator. When I traded it in at 98K the belt still looked fine. Spark plugs weren't an issue.
As an aside, the new Ford Triton engines (at least the V10s) no longer have caps, rotors, or spark plug wires. One coil per cylinder. Very nice...

It might be the brand of serpentine belt you buy, Fredwood. I replaced mine after 30,000 because of cracking, but the one I've replace it with has 50,000 on it now, and looks like the day I bought it. I think it will last forever!

If you're going through caps (and rotors) every 10,000 miles then you have a serious problem! If these are bad then your timing is shot to hell and you'll have the problems you're talking about.
In newer vehicles, remember, there is no distributor. Heck, there are no spark plug wires. This problem fades somewhat.
To all: I still repeat my earlier question. No matter what the interval (30K, 100K, whatever) what on earth are you going to 'tune' on a new engine?

There is tune in a tuneup, just replacement of the right parts at the appropriate intervals.

My truck runs fine with the old cap and rotor,its just that when I replace them every 10,000 miles my mileage jumps up 2-3 mpg. I think the reason that this happens is that the amperage is too high for the metal contacts in the cap. My truck is an 89 Chevy C1500 4.3 V6 with 120,000 miles and still runs great.
Yeah your probably right about quality brand name parts. I typically would buy what ever Chief, Trak or Autoparts club has in stock. You would think that the OEM stuff would be the best, but that has not typically been the case with me.

some major parts, like mufflers, alternators, a/cs-- i have seen OEM stuff with much better quality than aftermarket. But with little stuff like belts and hoses, i almost never use OEM.

A couple of months ago was going to put a new clutch in my truck. I priced out chevy OEM, autoparts club, pepboys,kragen...when with pepboys because it was cheapest for the whole kit. I never heard of the brand before but it looked good. Anyway, after I dropped the trans and pressure plate out I looked at the manufacturer and it was the same as the cheapo that I got from pepboys. Moral of the story...paid $157 for the whole kit which was OEM. Chevy wanted nearly $400 for just the pressure plate and clutch disk. BTW, the pressure plate and disk looked good after 115,000 miles. The pilot bearing and release bearing on the other hand were toast!
#26 of 26 oem parts & 100k

I put bosch platinum plugs in my 86.5 nissan v6 at the first tune up. Now with 87k miles, they still look great (I pull 'em and check 'em on my six-month services). So I think on my new Triton engine with no cap, rotor, wires, etc., will definitely make 100k without a "tune up" which to me means ignition system parts.
I still plan to inspect/replace the air & fuel filters twice a year and oil filter/oil 4x/3k miles, and checking hoses, belt, etc each time.
As for oem versus "part store" parts, I have replaced the dist cap & rotor with aftermarket parts twice, from two different sources, five years apart, and had failures inside of a year. Both were the distributor cap. Now I only buy oem cap/rotor from the dealer. costs more initially, less in the long run.
When it was time for a new distributor (the pickup module failed at 85k) I called the dealer who wanted $400 for a rebuilt unit (he did not sell new ones) and so I bought a rebuilt from the local parts shop for $250. I figured there was no difference in this case.
So, I guess the moral is that some aftermarket parts are good (Bosch plugs) and some ain't (generic distributor caps) and some are the same as you get from a dealer.
