ok I Have Searched And Came Up Short, My 03 evo is stock right now but i plan on upgrading i wanna make 450hp max now question is what bov do i need i dont want the stalling/drivabilty problems some one told me to get a twin vent bov???? i dont know what this is or if its anygood any help would be great

Thanks James

 

APS Twin Vent BOV...im getting one soon!!!

for now if you arent going to mod the hell outta your car just get a IX diverter valve...its much better than that plastic pos diverter that 05 and under evos came with...

hope that helps...
