the nitro plenum? just looking for an alternatine to opening it up at the moment. plus a 10sec run is a goal but gettin race fuel up here is near impossible as transport companies are gettin tough on carring dangereous goods. only other solution to race fuel is more hp & torque with the right tune. you can get nitto plenums from croydon racing developments or cv perfomance;istill think nizpro one works the best
