I now this has been beat up but I cannot find what plug a econo w2 head uses.

I have been using Bosch platinum, go back to these or another type?

Thanks in advance
Russ

id like to know too im geting my w2 race engine back up and running i think i had autolite 65 before..

I like NGK R-5672A-8, -9 or -10 depending an your compression ratio.The -8 is hotter, -10 colder.These would be for race use.I'm currently using the -9. I like the NGKs because they're a little easer for me to read.

More street for me, my compression is 11.5.

I run RN9YC Champions in my 11.2 W2 416. Jim

I have had good luck with n7yc run them for years in my w2 small blocks with 12 to 13 to 1 compression,,,they last 100 runs at 9.80s and have tryed race plugs but the car runs no better

For street NGK FR5 plugs.
