an 8 is way to cold, i had a 300hp 200sx and that was on 7's. an 8 will draw to much heat away from the cylinder.

QUOTE -

The temperature of the spark plug's firing end must be kept low enough to prevent pre-ignition, but high enough to prevent fouling. This is called "Thermal Performance", and is determined by the heat range selected.

It's important to remember spark plugs do not create heat, they only remove heat. The spark plug works as a heat exchanger
by pulling unwanted thermal energy away from the combustion chamber, and transferring the heat to the engine's cooling
system. The heat range is defined as a plug's ability to dissipate heat.

Whether the spark plugs are fitted in a lawnmower, boat, or a race car, the spark plug tip temperature must remain between 500C-850°C. If the tip temperature is lower than 500°C, the insulator area surrounding the center electrode will not be hot enough to burn off carbon and combustion chamber deposits.

on a saxo im not so sire, but an 8 is for a seriously hot engine.

id be going with an iridium MGK, number BKR7EIX

That makes sense to me - thanks for the advice!!

You wouldn't know if they are fitted to any car as standard would you?

As i could probably get them cheaper through work?!
