hotter spark plugs

[hudson_hawk]

i am going to run some hotter plugs in my SBC and i understand its one number higher, but i have to buy these at orielly so i can expect that they will have no idea what i am talking about.

so if my plugs are r44t, what should i ask for?
also, are the bosch that much better than delco?

R45T would be one measure hotter in AC Delco plugs. Bosch plugs probably won't give you much, if any, advantage over the AC Delcos ina typical street small block. They DO work better in late model stuff, though.

I've always used NGK in everything. FYI NGK is backwards. If you had a BPR7ES it would be cooler than a BPR6ES.
