On and off constantly isn't going to cause any more wear than a vehicle that is constantly on. The opposite might actually be true - less wear because the spark plugs are not constantly firing. Anyway, I would just change them as per the maintenance schedule. 192000KM I think....or 160000KM??? Can't remember, but I think the 192000KM is correct..

I'd follow the intervals reccomended by Lexus...it would be nice to know how many miles are on the ICE though.

Are the NGK Plugs just as good or better than the Denso?
