well cheap/ free. Only the coupling costs. Its like 7 bucks.

 

"free for me" doesnt constitute a free mod. The whisper lid is 120 bucks. and what ram air did you go with?

 

no like you can cut out the bottom part of the air box and get free ram air HP. The whisper lid is when you take off the fins on the stock air lid and then sand it down.

this is the free ram air . Just imagin the cold air intake missing

those parts you are showing still arent free. you could cut the airbox, but you still need to buy the scoop. i dont know where you can just pick one of those up. the free mods are the EGR and AIR deletes as far as I know. The only thing it costs was a small peice of aluminum.

 

no dude lol just dont buy a hood scoop
