Anyone ever tried Bosch spark plugs in a 900 or 1000 Kawi?

I haven't tried them in KZ's, but the only plugs that have consistently failed on me, in several different cars, were Bosch. Some didn't even make it a few months, whereas the cheapest of the cheap champions, in the same vehicle lasted years and years. Lesson learned.

I've had good luck using Denso W24ESU's. At one time I had a series of NGK plug failures that were real head scratchers, as the plugs would idle fine but would fail/act up under load.

Changing to Denso sparkplugs solved this problem.....

Where do you find Denso plugs? Can they be picked up at Autozone or O'reilly's?

Actually

Those plugs are no longer available on the open market. I bought every one left in the US from Denso. They're $3.99 each

Did you try to order any from them? Why don't you try and order four and see what happens.
