Anyone happen to know the BOSCH Plat. +4 equivalent of the NGK B10ES ... I searched the web, but no luck. Just want to make sure I stay in the same heat range.

Thanks for any and all help!

 

Just order the NGK's. You'll be good.

 

On a different note, would using colder plugs (Denso Iridium IK24) have a different gapping than stock gap of 0.039-0.043in? If so, what would be the gap for these plugs? BTW, my car is N/A. Thanks for the help.

Yeah ... I have used the NGK's for years, and would like to try the BOSCH. This is for a 2 cycle race engine.

 

For a 2 stroke race engine (ie shifter kart), you can try a NGK 105. That's a heat range between 10 and 11. I forgot the letter designation.

It works really well and is a special race plug.

Hope this helps
