Others fail by locking down and spinning at full engine speed all the time. When this happens the increased drag will rob considerable power and you will hear the sound of a lot of air rushing at idle and low speed."
May swap mine out. Worse case, it will make no difference other than peace of mind.

If you do let me know how it works out. Mine I hear it when parked and I tap on gas or bring the revs up slightly but that's it. Where is a good place to get one? I may invest in this as its worth the investment.
