Intercooler Kit

Unitronic's Intercooler Upgrade Kit for the B8/8.5 A4/A5 is a direct OEM replacement designed to significantly enhance cooling performance and support high horsepower applications, capable of handling 600HP and beyond. The kit features a substantial 20.5" x 4" x 8" bar and plate intercooler core, crafted from durable T5052 aluminum. This core, boasting over 80% more volume than the stock unit, is paired with T6061 cast aluminum end tanks and a proprietary internal fin and louver configuration. The intercooler's design prioritizes efficiency, drastically reducing charge air temperatures for maximum engine performance and increased resistance to heat-soak. This ensures cooler, denser air is ingested by the engine, preventing performance degradation often caused by high intake temperatures. The multi-ply, flow-matched silicone hoses and TIG-welded construction further contribute to the kit's overall performance and longevity. Installation is a direct bolt-in process, designed as a direct OEM replacement that requires no bumper, radiator support, or other trimming. The kit includes the Unitronic Direct Fit B8/8.5 A4/A5 Intercooler Core, Hose Kit, and Bolt Kit, making for a straightforward installation that can typically be completed within a few hours with basic tools and mechanical knowledge. Recommended software upgrades, such as Stage 1, Stage 1+, and Stage 2 (if equipped with Unitronic's 3'' Downpipe), can further optimize performance when paired with this intercooler kit. The specific fitment applications include the Audi B8/8.5 A4, A5, and Q5 models with the 2.0L TSI engine, covering a range of model years from 2009 to 2017 depending on the specific vehicle application.
