Iridium Spark Plugs

Just fitted in 4 new NGK Iridium plugs having paid $14 a piece. Definitely more power and consistent engine performance. I was initially doubtful whether it will bring about any benefits but having done so, I am pleased with the outcome.

Unless your old plugs were really fouled, then I can bet that the 'more power' that you could feel is more than likely something called the placebo effect.

It is the placebo effect, Iridium spark plugs are not bought for the sole purpose of performance gains.

Chances are your sparks needed a change and you're just noticing the difference between a standard plug that is old and a newer plug that is designed to be more efficient (though technically you shouldn't be using a single electrode plug!)
