Iridium vs Plats.

[Cubes]

Next year I am going to uni therefor I will be needing a plug that will be able to last as long as possible before changing.

Now I have the money then I wont..

So how do these Iridium spark plugs handle boost like 18psi worth.

I wont be driving it on that sort of boost all the time as I don't drive around with my foot flat, only occasionally.

The car will be making around 210rwkw lets say and will be running a tuned ecu. Hence not running rich.

I've emailed NGK and they seem to think with the above mods power levels I should be able to get 80,000km's out of them.

So what do you think ppls.. ?

Iridium or Plats?

I thought that iridium were replacing platinums.

Iridiums all the way man.

I had NGK R before & once i replaced the Iridiums on god did the engine felt like a new car. It ran so smooth.

Took a while to replace the plugs though since we got a pipe that goes right over the rocker cover

My car should be getting around 160rwkw nothing near what your car is making but i go for Iridiums.
