i want to put one on which one workes the best and do they really produce more hp and fuel milage?

 

Not worth measuring h.p. and torque that is if leaving rest stock.

 

More HP.....Not really by itself.

More MPG......Very very minimal (if any at all).

Lower exhaust temps.......Yes it will

More turbo whistle......Yes it will

I would highly suggest doing some research on the "search" tab because there is a lot of topics on air intakes.

 

Not going to gain you much unless you have a turbo/etc that is going to require the additional airflow. Be careful as there is alot of discussion on some of the oiled filters possibly damaging the turbos. And for that matter, some of the paper elements failing and getting sucked into the turbo. Probably the reason I haven't got an intake as of yet.

 

thanks alot i think i,ll leave it alone
