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?

 

Just use what's recommended from the factory.

 

ok guys. ill stick to what is recommended. i'm using the msd direct fire system. i was just curious because i wanted to know what spark plugs i should use for better performance and results. thanks guys appreciate the help
