alright i have a 93 del sol si d16z6 im about to put 50 shot on it and i am wondering whether to get 1 or 2 heat range colder. The guy at the parts store said im not be able to get a very good spark with 2 ranges colder so he said 1 should be fine lemme know ! i appreciate it.

 

im talking about plugs.

 

Call NGK. It's free, and they'll give you tons of great information. Don't even listen to anyone here, even if they're right. The guys at NGK will be more helpful and give you a lot more information, and make sure you understand it.

 

alright will do thanks

 

1 step down will be fine for a 50 shot.
