So im saving up for a Kinetix Intake Manifold and I wanna know what im getting into before i make the buy. My questions are

What other parts do i need with the Manifold?
Do i have to get a tune ?
Does it really produce 30 more HP/ better Gas mileage ?
Is this a hard part to install by yourself

any input from anyone with this part is much appreciated


thanks and i did do search
