I am currently considering an MSD ignition system for my 2000 ford
explorer.  does anyone have any experience with these systems? and can
you tell me specifically how to install it on an explorer.  i've read
MSD manuals online but they don't make too much sense to me because i
dont know that much about ignition systems.  can anyone tell me
specifically what kind of ignition a 2000 explorer has, and how it
works?  also, i know how the MSD ignition works, but how does it
connect and work in conjunction with my other ignition components?
thanks

The question bears asking... "Why do you want to install and MSD
ignition?"... Without a good "why", the rest is moot....

Well duh Jim, he'll get 100 more HP and 50 MPG!  And if he switches to
amsoil too, he'll get even more HP and MPG! It's a no brainer.

Gee... all he really needs is the MSD decal for the HP gain...

some people just can't recognize an excellent product.

I can personally vouch for the MSD ignition.  Once I got all of the kinks
worked out, the product worked great!!  I don't even have to use gasoline
any more; my car runs on water alone.

One drawback; you have to use distilled water.  Otherwise, the injectors get
clogged.

Well that's just great because bottled water costs 3X as much as gasoline.

Everybody knows that you can make more power with "Perrier" bottle water. ;-)

I used to think I wanted that too. I saw an impressive MSD countertop
display at a local speed shop. The MSD plug unleashed a *dazzling*
display of sparks compared to the wimpy plug next to it.
Then A&P school changed my mind.

Ignition wires in aircraft are specifically meant to prevent multiple
sparking. It just shortens plug life.

Shielding around cables reduces radio interference.
Shielding + inner conductor acts as a capacitor, which fires the plug
again after the main spark event.
Resistance in conductor prevents that capacitive afterfire.

Since every spark will transfer a bit of metal from one electrode to the
other, MSD seems like it would eat plugs fast.

Multiple striking is meant to keep the plugs clean and ensure that these
lean mixtures are lit... obviously, aircraft maintenance requirements and
schedules are vastly different from those applied to automobiles.... Many
late model engines feature multi-striking from the factory... Aircraft don't
have the same requirements for emissions.

At the same time, the factory ignition system on any stock engine, should be
adequate for the task at hand...

Ah, never heard of the multispark stuff. I thought there was sometimes
just a wasted spark on the exhaust stroke.

Sure don't, avgas is exempt from the lead ban. And mixture control is up
to the pilot, so it's seldom going to be just right. But on the bright
side, there are dual ignition systems.

My "magneto" instructor told a story about when he was a kid driving his
dad's old Ford farm truck. The engine caught fire, so he peed on it in
an attempt to douse the flames, and got a shock that threw him on his a.s.
