In theory???
I guess then, since you have never replaced any then you would not know the benefits or be able to comment on them.
I get into this argument with members all the time who never bother to think about the possibilities before continuing with " oh that's stupid" but are clueless as to why .
I have done many cars older than 5 years with this simple maintenance replacement.
No one ever says it will make your car faster if they are being truthful but why throw money at gaining HP when you lost ones you had already for an easy fix.
