Iridium spark plugs 912is

[toung]

Hi, 
Can I use the Iridium spark plug
NGK DCPR8EIX 6546 (removable nut)
with my 912IS 
instead of NGK DCPR8E 4339 original plug?
Any idea?

Good question for Lockwood.

I don't have a IS engine but I thought the fuel injected IS engines required the Rotax 297656 plugs.

I would stick with the NGK DCPR8E. There is no advantage with the Iridium and the original NGK's are cheap enough to replace with new ones every annual.
Rotax specifies the 297656 for ALL 912 series but "It is not mandatory to retrofit engines which are currently equipped with old spark plug types and old spark plug connector types." At $30 each the Rotax plugs are silly expensive.
