i was planning on buying new spark plugs and i was wondering if it would cause any damage on my motor?? i am currently running 4 bur9eq spark plugs in my 13b streetport. now, would running 4 bur7eq leading spark plugs be a good or bad idea??? has anyone tried this??? i need some opions please

the numbers have to do with the heat they burn hotter or something i think. no it doesnt do any harm some say there is advantages

Do you have direct fire? If not, better to use BR8EQ-14.

rx7allnight is right. its not going to function properly. you can use 4 trailing sparks but the leadings work colder so no it wouldnt work with 4 leading spark plugs. what is wrong with using 2L and 2T sparks anyway?
