Will i gain any speed with a racing plug and if i do how much speed

 

well, no, and yes. if you mean by putting in one of those quad-fire(no pun) plugs, you *could* burn through your piston. because those have the spark going down, while others have it off to the side,
the best thing to do is get a good plug, not some cheap one. one with all the extras.

 

Mongoose,

What exactly is a spark plug with all the extras? Should I get the power window and air conditioning options? Would this help?

Specific spark plugs are made for different applications (based on bore / stroke / compression / ignition / temperature etc...). Visit your local shop and get the plug that is made for your ride. Spark plugs with hotter or colder ranges are seldom needed for a stock motor. Now if you have a modified motor or your spark plug is wore out, a different/new spark plug with the correct heat range could seem like a "racing" spark plug! By the way, I am looking for a spark plug fully loaded with all of the options. I am sure that my horsepower would double then! If you hear about one at a reasonable price..E-mail me.
