probably not. you might be able to but it probably wouldn´t be worth it. the quickest mod is to bump your timing to 14 degrees BTDC. after that you need to spend money on intake/exhaust etc. Don´t get too cought up in the hype of plugs and wires. stick with good quality wires and Bosch, NGK plugs. platinum will last longer but do NOT add any power.
