Changing Spark Plugs On Is200

[DINO]

There is no standard for heat range.

Denso heat range is 20, NGK is 6. For your mods Zee I would have thought you need to use the next number up for a slightly cooler plug.

Denso part number is SK20R11

14 mm thread - Iridium tipped, 20 heat range, Resistor, 1.1mm gap.

So which one is better, Denso or NGK?

Sorry di not read the rest of the thread before placing comment. I have a Standard IS200 Sport, I guess I will go for the Denso IK20's. Cheers.

Garages relpace plugs every year in your annual service surely, so theres no need for long life ones if you get new ones every year.
