Sorry,after looking in my new spark plug catalogs I've found that some spark plug numbers I just gave are obsolete now,the plugs have been dropped from their offerings.
Bosch has dropped some of their colder plugs,I don't see the WS5E and WS5F anymore,and the only "6" plug is the WSR6F.
NGK does not make the Gold Palladium "V" plug in 1/2" reach anymore such as the B7HV or B8HV.
NGK's best plugs in the "shorty" type 3/8" reach are the "Y" types which features a "V cut" electrode,such as the BM6Y,BM7Y,and BPMR8Y(Coldest),they are also available with resistor(R),or extended tip(P). These are nice spark plugs and maybe the best stock replacements. :msp_thumbup:
I'm trying to find info about Champion possibly now making some 3/8" shorty fine-wire plugs,don't know for sure yet,Champion doesn't seem to like to publish any new catalogs online,I have to search a dealer catalog...
I did find a few Champion numbers for 3/8" racing plugs in their racing plugs data- they listed a J6C and a J4C. There were no details on these plugs so I don't know anything about the design type or availability. I will try to order a few and see, or call a Tech line number I found,so I'll let y'all know what I find out.
