Just noticed on the group buys there are 2 different buys going on for iridium plugs.....

NGK and Denso

Are these for all models?

Any difference between the 2 (in reality)

How much are they if they are part of a service?......(is it a rip off price from main dealer?)

Can you provide them and hence save on a service charge?

TIA

Wikipedia Iridium

iridium is a chemical element in the periodic table that has the symbol Ir and atomic number 77. A heavy, very hard, brittle, silvery-white transition metal of the platinum family, iridium is used in high strength alloys that can withstand high temperatures and occurs in natural alloys with platinum or osmium. iridium is notable for being the most corrosion resistant element known and for its association with the demise of the dinosaurs. It is used in high temperature apparatus, electrical contacts, and as a hardening agent for platinum.

The KT event of 65 million years ago, marking the temporal border between the Cretaceous and Tertiary eras of geological time, was identified by a thin stratum of iridium-rich clay. A team LED by Luis Alvarez (1980) proposed an extraterrestrial origin for this iridium, attributing it to an asteroid or comet impact near what is now Yucatan Peninsula. Their theory is widely accepted to explain the demise of the dinosaurs. Dewey M. McLean and others argue that the iridium may have been of volcanic origin instead. The Earth's core is rich in iridium, and Piton de la Fournaise on Réunion, for example, is still releasing iridium today.

Welcome Andy! :D

S/C = Supercharged

T/C = Turbocharged

If your is a standard IS200 then it seems like you need the IK20 plugs.

As a side question, my IS200 is nearing is 70K service (got a few thousand miles to go), will I need to get new plugs? The 60K was done by a Lexus/Toyota dealer by the previous owner and cost him £560! :sick:

Anees - the 60K service includes replacing the plugs. However the recommendation for the Denso iridium high performance plugs is every 30K

Guys just managed to stumble on this thread and see something about the SC and new plugs!! I have the Supercharger being installed on the car on Saturday week and was wondering if the Denso IK22's would be a good investment?

It would be easy throw them in since the engine cover is coming off for good! lol
