Stock intake already draws air outside of the engine bay.
Inlet is just behind the passenger side fender forward of the wheel under the liner.
It's a true cold air intake.
I find the stock intake suffocating, like my Indian bikes, the first one I went all out on expensive intake, exhaust and tune.. then on my Springfield I just took air cover off and left it off, put KN on with a tune and exhaust. ...
So on my 03 sequoia, I saw thread about home made Intake, basically hold saw the air box and run a tube to front. $40
I just opted for cutting the hole to allow more air in to the box and works just fine for me, throttle is responsive, no sounds like the engine is starving for air.
coming next, Gibson stainless exhaust.
