Well just like the title says I am due for new spark plugs and am just getting confused when I search because people are talking about gapping and protruding tip and I understand a little but need some help. I have a 2005 gsr evo with basic bolt ons(down pipe, high flow cat, bov, and more basic bolt ons coming) my question is...

-What is the best spark plugs for an evo w/ bolt ons?

-I daily drive the car and its 50% aggresive and 50% legal so if there is anything to factor into that.

Thanks

-Matt
