Hey guys, paid 170.00 for the RD Intake for the Z4 3.0i but after I got it I was disappointed on how simple it looked and I just couldn't justify the price....so I returned it and made my own.....Total: $35.00, sounds louder (Better than my mute 335i
, need a CAI) and I can actually FEEL that the car has gain a fair amount of torque
