Ok, well I just couldnt do it and even stop by the dealership to see how
much they would give me for my Dak. I am an addict, what can I say. The Dak
is here to stay. I have the following 'performance' mods', and would like
some help from anyone and everyone on this:
*MSD 6-Offroad Ignition, MSD RFI Noise Filter, MSD Universal Wiring
Harness, MSD 8.5MM SuperConductors, Accel Super Coil, Borg Warner
Select Brass Cap/Rotor, Autolite Copper Plugs(.050), QuickD Throttle Body,
Ford Motorsport #19lb/hr Matched Injectors, 'PoBoy' Homebrew Cold Air
Intake Kit Using GenIII Dak Air Hat, K&N #RE-0920 Cone Filter(900+ CFM),
K&N Breather Filter(PN#62-1520; All Metal), Flowmaster 3Chamber Delta-Flow
Muffler

How long do the Autolites typically last for with the MSD system? I have had
them in for 6,000 miles and have typically replaced them at 8,000. Anyways,
I am going to splurge and spend $6-$7 and get some new Autolite Copper spark
plugs. I am also going to spend the $12 and get a new Borg Warner Select
Brass Cap and BW Select Rotor. How long have caps/rotors lasted for everyone
else? I checked the ratings on all the MSD 8.5MM Super Conductors today, and
found that all were indeed perfect. They have been on my truck for 30,000
miles(since Feb-'99). So the wires are fine. As Jon found out, and
recommends now, I am also going to swap out the Accel coil for the stock
coil. The Accel coil has been in since 101,375(Feb-'99). So the stock coil
does have 101,000 miles on it. I might price a new coil if the stock one
acts up and just go for the stock one, price pending. I think the Accel coil
ran me $60 when I bought it. Will I still be able to run a larger spark plug
gap with the stock coil? If so, should I stick with the .050 gap or go a tad
smaller? What gap will give me the best performance and gas mileage?

I am going to put in a new pvc valve, for $2 whynot. Current one has been on
since109,950 miles, so it is time for a new one anyways. I typically replace
the fuel filter every 15,000 miles. The current one has 13,000 on it, so
once again I am just going to spend the $13 and get a new one. Hopefully by
putting all these new, and CHEAP, parts on my Dak I am start to rule some
things out if the mpg doesnt increase somewhat. I mean for $40 I can get new
plugs, dist.cap, dist.rotor, pcv valve, and fuel filter.

Ok now onto a bit more expensive part, the O2 sensor. Since my original 02
sensor lasted for 100,000 miles, I just bought another for $85ish and put a
Mopar sensor back in. This was at 105,000 miles and I just dont think, or
dont want to think, that it could be bad this fast. Any thoughts?

I am also going to do a thorough cleaning on my QuickD TB(and sensors), with
Gumout's Throttle Body Cleaner. Anything else that may be worth checking and
replacing? Thanks alot for any info at all which may help me and my Dak.
