Spark Plug Difference! HELP

[ZiviCase10287]

My friend doesn't believe me that going from STOCK spark plugs to aftermarket plugs (bosch platinum +4) and having the fuel pressure regulator set at the same that i won't feel anymore power from the plugs alone.... he said it can only combust in a 1 way, so i'll only THINK i am feeling more power, but yes that 1 way is more efficent with aftermarket plugs....... correct me if i'm wrong but the more spark the better combustion, which means more hp? Am i right and dyno charts or articles posting this topic would be helpful.

I think you need to reread that and do some editing.. it hurts my eyes.

Yes, better plugs = better spark = better combustion = more hp (if tuned accordingly)

[ZiviCase10287]

what do you mean if tuned accordingly? the bosch say it doesn't matter on gapping... so not unless you mean something else?

Platinum isn't as good of a conductor as copper, but it lasts longer. Platinum plugs are for longevity. Copper plugs will generally perform just as well or beter than platinum plugs, and they're cheaper.

The platinum +4s are a big load of doody.

If you feel the need to spend a lot of money on spark plugs, send the money to me, I'll get you some nice copper plugs, send them back to you and even use some of your extra money to pay for shipping out of the goodness of my heart

Bosch +4's are one of the worst ever designs for spark plugs.

one: electricity takes the path of least resistance, therefore, it will only spark from the center electrode to one of the four outer electrodes at any one time. in other words, it'll be no more powerful than a stock platinum plug.

two: 4 side electrodes further shroud the center electrode more than a single side electrode. this keeps the spark away from the conbustible mixture, causing stumbling, poor throttle response, reduced fuel economy, and higher emissions.

three: platinum is a horrible conductor compared to copper/nickel or iridium.

four: you'll "feel" an improvement with ANY plug, normally because your car was in need of a tune up anyways and already lacking power due to this.

five: all plugs must be properly gapped and have the proper insulator sizing to prevent detonation and/or misfiring. only the Bosch +4's cannot be gapped due to it's design.

copper, save your money. There is only one conductor better than copper, that is silver, and they don't make silver sparkplugs, and they'd be wicked expensive.
Just get copper ones, your car will pull hardest with those.

Well, gold is better than silver, but obviously neither are strong enough to be used in a combustion chamber.

you're right, I was thinking of magnectivity (or whatever its called)
