Probably is not going to make much of a differance. I would change it when/if you change the cam.

I have one and when installed with the LS6 intake and throttle body I had it put in car felt alot better. There good for about 10hp. I only paid $200 for mu Asp underdrive crank and with a A4 you should get the overdrive alt. pulley for better charging.
