Default Re: Would you recommend a hotter plug?

I used C16C from 1962 until 1979 when they discontinued them.

All my driving (40,000 miles) was 50 mile minimum round trips at 50 MPH.

Then switched to W16Y that Champion said was same as C16C.

At the same time we moved into town so trips were much shorter and more frequent.

I found the W16Y to be too cold as Purdy said especially after we moved to town.

Never got the chance to run W16Ys on highway for any regularity.

W18s work just fine.
