Part # CI100043
This is the ultimate intake upgrade for the Audi S4 and S5 (B9). It flows 31% more than stock, reduces pressure drop, and improves turbocharger efficiency. This directly translates to +19 AWHP and +20 AWFT-LBS of torque on top of our Stage 1 (93) tune making this a simple upgrade for more power you can feel.
Our kit includes everything you need to bolt on and go. No new tuning is needed to run this product, and the product is emissions friendly. We include all new OEM gaskets and all the nuts, bolts, and clamps needed for an easy install. Lastly, thanks to our billet turbo inlet adapter, this is the only intake you'll ever need. Should you later upgrade your turbo, a new, larger adapter can be installed to adapt to the larger inlet simply by swapping out the billet adapter!
