The intake could definately cause you to fail, not sure about the others ... Neuspeed's intake is CARB-approved, but most/all others are not ...
Anyone know about exhausts? I'm trying to keep my car legal but wondering what I could do engine-wise to get some more power, its stock right now ... K&N with Neuspeed chip &/or Neuspeed intake are legal but don't know about anything else.
