Full-Race who makes intakes and other performance parts for the 3.5 Ecoboost actually recommends you remove them when installing their CAI. I guess the proper term for them are "attenuators".those look more like air straighteners. you need those
As I was reading through the provided links yesterday, I got the impression that they are not a hindrance unless tuned, as well.Well I've read that unless you tune your car without them keep them in. But again I'm going by the mazdaspeed community that actually tested the honeycomb vs no straightener theory.
I figured they did since most new cars do now a days and at least you can hear the whine better.Well it's been confirmed the 2.7 does have the silencers and once they are removed there is definitely an increase in turbo whistling.
arnt you running turbosmart bov though?They are going to be located right before the turbo right here.
