So I been looking at some engine mods I want done to my Audi its an 01 s-line a4. I was looking at the apr diverter valve because i want the swhhh sound when im shifting. If i get the diverter valve would it be a good idea to get a cold air intake as well so its a louder sound when im shifting or will i be alright with just the valve?

 

I have no idea why so many people are concerned with their car making a "swoosh" sound as oppose to it actually running good, I see this question asked way too many times, if you search around you will find your answer..

 

I got a APR R1 diverter valve in my 01 a4 and it sounds nice. Don't bother with getting a cold air intake. Audi makes a superb intake already so keep the money and spend money into other engine mods or even get a chip for it.

 

I been doing a lot of reading on the apr dv and im still not sure if its going to run properly with my engine being completely stock. please help!

 

It will run properly with a stock engine. It will just be able to hold more boost and recirculate the air faster than your stock DV would. I also recommend getting a chip. Best of luck to you
