has anyone found the replacement Bosch plus 4 plug for the 390 FE? Autolite number is a 45.

I am still trying to locate it..... I might be calling Bosch tomorrow.

Thanks

There might not be an plug for that application (18mm) low demand might be the issue? Just a thought.

NGK makes a platinum for the 390.. No. WR5VX. They have never fouled, and I replace only because its a new driving season.

I buy them from Club Plug:

dont run platinums if you have MSD ignition or you will burn a hole in the top of the piston or slow your motor down or both!

Platinums don't work with the Jacobs Ignition either. Motor runs lousy and same results as stated above.
