Yeah the search feature definitely helps out, I've found quite a bit of info on what I've had to look for before by running a search.
One more thing bud, instead of adding a new post if you find something or forgot to add something, just click the "edit" button which will allow you to modify your existing post. I don't think it's worth the $6 a plug for the bosch platinum +4 plugs. Invest in some AC delco plugs, you are probably better off.

Autolites are very good plugs as well...
Those Bosch +4's are a rip off. Completely unnecessary. Someone else mentioned, however, that the +2's are nice for just the reason that they have a good, direct escape path for the spark since the direct center of the plug isn't covered by 1 large electrode, rather centered between 2 smaller electrodes.
While we're on the topic of ignition also....don't buy the Splitfire plugwires either. I almost fell out of my chair laughing when I read those ads.

The only reason those plugs feel good to most people at first is because they don't need indexing- there really is no way you can. But they are still shaded from the valves slightly, AND have four obsturctions to the charge instead of one. Use Autolites (regular A/C Declos are bad- but rapid fires burn up as quick as Bosch +4's. Just look at the tiny electrode. And Most of all- index the plugs. It takes time, but will give you better power no matter what plug you run.

accel plugs are great, they last forever and I have never had a set or 1 foul.
Wish I could getthem for my bike. I can foul a NGK is seconds.

The Splitfire wires, if I remember right, claim better spark energy due to their 'dual conductive paths'. The wires are 2 conductive cores twisted around eachother.

Too bad electricity always takes the shortest path! 
That's why people thought the splitfire plugs were junk; they thought the spark "split" into two. Uh-uh... no way; Splitfire never even claimed that for the plugs. They claimed less shrouding of the spark, due to the opening in the split-electrode. Sort of like the effect that a cut plug would generate, without the longevity issue.

From a Splitfire plugwire ad in Summit:
"In tests, Splitfire's Dual Mag Wire showed 92% lower resistance than stock carbon core wires. Splitfire uses two wires instead of a single, equivalent-sized wire, greatly reducing resistance and getting more power to your plugs."
