Are you sure about the 45s ? Everywhere that I checked they say 46s.

46or equivalent for a stock engine. 45s tend to be best for modified engines

My engines see lots of hiway mileage so I prefer the cooler plug, I don't think the difference between the two is that great? I use them in my 223 I6 and a stock 390FE also and have never had a problem.
