You're not just building a run of the mill bolt-on car with cheap imported parts. No, your Audi B8 A4 or A5 project deserves true performance designed mods and the best cold air intake available. This is not your average filter on a stick, IE engineers used specialized computer flow analysis software coupled with 3D scans of the engine bay to maximize performance. The result is a unique intake shape that optimizes flow and reduces air restrictions for an unmatched bump in power. Factory-like mounting solutions are used for a perfect fit and long life. Your new intake will fit like it was there stock, but perform and sound like a true motorsport intake design.
Installation is quick and easy to install with basic tools. The process should take under an hour for most enthusiasts. CLICK HERE to view and download the IE B8/B8.5 A4/A5 Cold Air Intake Install Guide.
CTS Turbo B9 S4/S5 3.0T (EA839) high flow cat is made to maximize exhaust flow for highest power gains. Do not compromise performance and sound with factory parts – unleash your B9 S4/S5 3.0T potential!
Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from cast T304 stainless steel, hand TIG welded and back-purged to ensure years of reliable performance.
In addition to unleashing the power and performance of your 3.0T, the CTS B9 S4/S5 3.0T EA839 high flow cat will make your vehicle sound like an S-car really should. When installed with factory exhaust it produces a sporty growl with much more pronounced exhaust “crackle” on downshift. While up-shifting you will enjoy a confident “braappp!” as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system.
