You will hear some noise all the time with either one.. If you don't want to spend a lot get one from CXracing and just buy a better filterTo those who put SRIs (Cold Air Intakes) on an automatic: how much of an increase on BPV noise did you notice? Can you hear it in regular driving or just under a lot of throttle? I really want to hear some turbo noise but don't want to waste $300.
sRI=short ram intake CAI=cold air intake
