Now I did not remove my snorkel but wouldn't even make a diff if I did. I didn't gain any hp or any torque ( to my knowledge and if I did its prolly by a decimal) if anything it made my car louder. If there's a box near the air filter ( not shown in pic) then u can suck less hot air and more cold air and possibly gain a tad more power. But again it's not gonna be OVER 9000! Type bs lol.
