regulars,v powers ngk ,platinum ,doble ,triple, 4 electrodes,bosh ,iridium,etc

wire are wire get NGK, they will be good enought. For plug, all plug do the same thing the only different is they melt the tip except the iridium, Iridium have a hight melting point that they will never need to be replace. I have a set for four years.

unless youre in a very high performance setup, very little.

in terms of horsepower, very very little improvement. if its pretty much a stock setup (no fuel system upgrades, or major power gainers(intake and exhaust are okay)) then stick with whatever the manufacturer recommends. if you do have some major power gainers or are planning to buy them, then buy the absolute best ignition system you can afford. you're bound to make more improvements from there so just spend the money one time instead of continual upgrades to your system.

little or nothing. ther just spark plugs. if you wanted some serious HP gains, then look into turbo, supercharger with the usual additional items like BOV, and intercooler.with the popularity of NOS in recent movies, i recommend not to get NOS. please do not use it on you car.. your more than free and more than welcomed to use it if you want to see engine parts flying out from under the hood or really mess up the combustion chambers. sure, it boost HP like crazy, but at the same time, messes up your engine each time you hit the NOS button and NOS is used..i do not care if its dry NOS or wet NOS, still messes up engine.
