....I don't know what the heat range is as the part # doesn't correspond to anything on Bosch's website charts. I suspect that it's a 6 and I'm told it's a cold plug by the vendor. I don't know if spark plug companies have even standardized the heat range specs. I have searched the NGK and Bosch websites and Monarch's site as well this site and others w/o success.



Would appreciate input.

Why Bosch?

whats wrong with ngk?

I'm lookin' for mo' pow-wa'?https://www.nopistons.com/forums/pub...1047683358.gif



Nothin' wrong w/ NGK. https://www.nopistons.com/forums/pub...1047683329.gif

then run ngk 9's or 10's

NGK > Bosch



No? https://www.nopistons.com/forums/pub...IR#>/dunno.gif

Bosch = botched.

It amazes me that everyone who replies to my inquiry doesn't have a coherent answer, rather ya'll spew your usual useless garbage because I suppose it's all you know and you love to see your jibberish in print.



I regret posting, nonetheless, if I find an answer to my question - hell, better I probably keep it to myself and shut the Hell up before I hurt somebody's feelings.

Look at the bottom of the page.

If it's a Bosch heat range "6", it's too hot for a rotary, unless you only drive it 2 miles at a time?

It's equivalent to an NGK heat range "6".

Oh man, YOU are the Man! Now I gotta return those plugs and reorder. Or, just stay w/ NGK. Thanks a bunch.
