The best plugs for imports running any type of forced induction have always been NGK Copper Spark Plugs. These plugs are one step "colder" than stock and take well to increased boost or the addition of race fuel much better than the stock recommendation of the BPR7ES. These plugs are recommended for Evo's with mild to moderate bolt-ons modifications.
For Evo Models IV - VIII. Sold in sets of four.
