Good Spark plugs and wires???

whats the difference between autolite platnums and double platinums? I just installed standard platinums on my ranger, and was wondering what the difference was between them.

Nice diagram, much easier than trying to explain the schematic. If I remember correctly, isn't it the passenger side that corrodes the electrode 5 times as fast as the driver's side?

Also, I seem to remember pulling alot of OE plugs that were double plat on one bank and cheap non plat on the other bank. I beleive they were installed like this from the factory. It is entirely possible that I am thinking of a different dis system though.

Actually, the OE plugs were single platinum, 2 different P/Ns, with a platinum center electrode in one bank, and a platinum GND electrode in the other bank.

With single platinum, only the center electrode has platinum, with double platinum, both electrodes have platinum.

Napa's premium plug wires are awesome, cheap and very high quality, i've ran them on every vehicle I've owned.

Not only this, but they fire every revolution of the crank, twice as often as with a conventional ignition.

Clarification. Are you saying that only one set of plugs in series with each other fire each crank revolution, or all plugs fire each revolution, or two plugs fire each crank revolution following the firing order? shady

All plugs fire for each crank revolution, 2 together at a time. With the 2 firing together, one cylinder will be near the top of the compression stroke, the other cylinder will be near the top of the exhaust stroke. With a conventional ignition, the plugs only fire near the top of the compression stroke, so the crank will make 2 revolutions for all the plugs to fire.

You're saying all 6 plugs fire simultaneously each crankshaft revolution? shady

No, they fire sequentially, 2 at a time, until all 6 have fired in 1 rev. of the crank!!

That wasn't clear in your post, and the novice may have been mis-led. shady

Motorcraft plugs and msd wires and your set. Also a brass terminal cap and rotor kit and your good to go.

I usually run the motorcraft plugs and whatever set of wires is the cheapest.
