why change spark plugs????

Well i hear about ppl changing their spark plugs which provides a noticeable change in performance.

Well, spark plug provides the spark for igniting the fuel in the chamber, so what do these new performance spark plugs do more than sparking?

How much of a performance boost can be achieved and will it affect the FE?

New performance plugs wont do anything other than sparking... he he...

Just that hey have more efficiency and precision than the cost efective ones used by the companies... You could get longer life for the plugs... Better spark plugs means you get better combustion in the chamber... Which could improve your engine efficiency (Efficiency doesnt mean FE)...

If you are planning to get one... Go for iridium plugs from any of the better known makes...

Rightly said crazy driver,better combustion of fuel = more efficient performance from the engine.I use NGK iridium plugs on my getz

Iridium plugs are, by themselves, not a performance booster. When an engine's boost is increased thru TCs, changing ignition timings, alter fuel mixtures etc. more capable plugs are required to handle this enhanced situation - and thats where Iridium plugs complete the loop.

Iridium plugs, are made of Iridium which is 6/8 times harder/stronger and has a melting point 1200 degrees higher than the platinum in normal plugs, is much more capable of handling harsher envorinments like a TCed engine's forced-induction combustion chamber. Also, Iridium plugs have a typically colder heat range than normal plugs, resulting in better heat disspiation from the combustion chamber to the cylinder head.
The key advantages of Iridium plugs therefore are increased efficiency, durability and firing power.
