MSD igniton
Please excuse my ignorance, what is a MSD Ignition, what are its advantages, I understand it has performance advantages, but are there any downfalls to it? How hard are they to install and are they even available for my truck. 1995 250 5.8 4x4
Thank you for your time.

MSD stands for multiple spark distribution. The msd box is very easy to install(have one on my 93' 460). It makes the coil fire multiple times per cylinder firing up to 2000rpm or 2500 rpm and above that it makes the spark fire longer. If you are running below the above mentioned rpm alot it makes a difference. I get better fuel economy(about half mile per gallon, not bad for a big motor).

MSD stands for multiple spark DISCHARGE.
Advantages: Smoother idle, easier starting, less emissions, more power. Their products also allow the user to make adjustmets to things like timing curve, high RPM retard, rev limiting etc. which is a must on some modified motors when stock set ups wont work so well. Some motors benefit more than others and some people can't even tell the difference between stock ignition and MSD on a stock motor.
Disadvantages: None really...just cost, more parts to fail, engine clutter.

So would this work well on my truck, f250 4x4 5.8 5speed? Is this an upgrade i should think about purchasing, i have a set of shorty headers and a true dual exhaust, with glass packs. Thats it as of now, but im looking to gain hp and torque, is this something i should consider? thank you for your responces.

We are talking more along the lines of a 6AL, 6A or the off road version.

The MSD 6a box + blaster coil+ 8.5 or 9mm Wires +MSD cap and rotor kit+ decent plugs , is the setup to get, may as well get the whole setup if you are gonna do it.

I use bosch platinum with the 4 side electrode plugs. It wears the plugs out faster so a premium plug is required and these have worked great for me. As for wire I have no preference, change them every time I change plugs.

Most prefer the Ford Racing 9mm (summit) and NGK v groove copper core , from what I have read you can gap those to .055 instead of the stock .044. They are what I am putting in my truck this weekend.

Well they're in there now gapped at .043 I think it is, according to what under the hood says.. does that mean I can run them at .055 as they come with my stock ignition? or just better to wait and open them up when I get my ignition?

NGK v-cores work well out of the box with a stock ignition at 0.055". If I run autolite plugs with my setup, I cannot gap beyond 0.048" without missfires.
Pull them out and try gapping at 0.055". If your plug wires are in good shape, you can let that 5.0 eat.
