Greetings All

I am new to the site, please excuse my ignorance.

I have just purchased an Audi S4 she's a beauty, I live in Africa so temperatures are severe, and the stock I/C may not be enough during our hot months or if the car has been tuned.
Has anyone installed the APR cooling system or any other? Which do you'll recommend?
Further what Mod's do you suggest are safe and will enhance the already brilliant car? I was considering software (Revo or APR) and Exhaust Decat and then maybe the cooling system and perhaps the SC pulley.

Many thanks
Eli

 

I went with APR's new RSC (Reflective Sound Cancellation) exhaust system. A bit expensive but I would have to say it was worth it. I paid 1,200.00 for the cat back system. Sounds very good and was easy to install myself. I was able to rip out the stock exhaust and install the new one in about 45 minutes.

 

what year is your audi S4?

 

i'm guessing B8. I think this is what he is talking about.

APR B8 3.0 TFSI Supercharger Coolant Performance System

 

Hi all

Yes it's a B8 S4, I have investigated APR's cooling, pulley and exhaust etc.
However it appears the tests were done at sea level, it appears the only way to extract any decent gains is with Stg 2 probably APR, incl pulley, but thats a lot of dosh for what would be prob 40kw (54hp) at our altitude 2000m above sea level.
