S2000 Spark Plugs

[Qube]

Has anyone replaced their spark plugs with Denso Iridium IK 22 plugs ?.

If so, Are they any good ?

There's a big thread on s2ki about spark plugs. IIRC a number of people were worried about the build quality of the Denso, so stuck with NGK.

Now an urban myth!
There was a batch/period where they caused issues with tips disintegrating possible due to people try to "adjust" them wrongly. Nothing in recent history

I have had IK24's in my supercharged S for ~8k miles no problems!
They are what was sent with the kit from Comptech!

Thanks for the replies. The IK22 come pre-gapped at .44. I'm sure I read somewhere that Denso make NGK. I checked the tips of my plugs about a fortnight ago, the car has covered approx 30k and the oem plug tips are rounded. looks like i better order a set of 22's soon.
