Unitronic Intercooler Upgrade and Charge Pipes for MQB Tiguan 2.0TSI Gen3B - Now Available

Feb 02nd, 2022 Products

Unitronic® is proud to release its Intercooler Upgrade and Charge Pipes for the MQB® Tiguan® equipped with the 2.0TSI Gen3B engine. These upgrades have now been re-engineered to add MQB Tiguan fitment to the catalog, offering the same level of performance and exceptional fitment you've come to expect from Unitronic.


This direct OEM replacement bar and plate intercooler comes with our all-new black finish and provides a dramatic reduction in charge air temperatures to ensure peak performance is achieved and sustained while resisting heat-soak after repeated efforts and in harsh climates and conditions.


At Unitronic, development begins with setting the objectives; performance, efficiency, aesthetics and quality. Operations start with 3D scanning the 2.0TSI Gen3B engine bay and OEM components with it’s in-house 3D scanner. Once 3D scan data has been collected and processed, Unitronic Hardware Engineers then interact with the 3D models to identify fitment constraints, mounting locations, other component locations, etc. to ensure the final product fits perfectly within the “envelope”.


In the case of the MQB Tiguan, provisions needed to be made in order to accommodate the factory oil cooler. As such, Unitronic Engineers incorporated support brackets which help retain OEM fitment and oil cooler performance in this area.


With regards to performance, there is no doubt your Unitronic tuned vehicle can benefit from a Unitronic Intercooler Upgrade. Our bar and plate intercooler core features a unique staggered and louvered fin configuration to maximize efficiency, significantly reducing charge air temperatures allowing for cooler, more dense air to be inducted by the engine; ultimately resulting in an increase in engine performance.

When intake air temperatures reach a specific threshold, the engine control unit begins to compensate to account for the air temperature, resulting in a decrease in performance. Unitronic's core measures 23.5” x 2” x 16.5" (597mm x 50mm x 419mm) a 60% increase in volume over stock, allowing for a greater volume of air to exchange heat, which, combined with a proper fin configuration, allows for maximum efficiency and reduction in heat-soak thresholds without producing a significant pressure drop.


Unitronic's Charge Pipe Upgrade Kit for the 2.0TSI Gen3B is a perfect compliment to Unitronic's Intercooler which is comprised of an upgraded Turbo Discharge Pipe, Throttle Body Pipe and silicone intercooler inlet/outlet hoses. This complete upgrade kit features a high-flow design that eliminates restrictions in the boost (charge) piping leading from the turbocharger outlet to the engine, allowing for unrestricted airflow.


With a larger 60mm internal diameter (I.D.), matching multi-ply reinforced and fluorolined silicone couplers, smooth transitions, and fewer restrictions through optimized routing of the one-piece mandrel bent lightweight Aluminium tubing, Unitronic’s Charge Pipe Upgrade Kit will remove restrictions through the intercooler plumbing. Unitronic’s multi-ply reinforced silicone hoses are more robust than the factory hoses and will not expand/balloon with higher boost pressures. Additionally, Unitronic’s silicone hoses feature a fluorolined inner layer to ensure resistance to oil penetration. Standard silicone hoses are likely to see oil penetration and degradation over time from the lack of fluorolining.


Unitronic’s Throttle Body Pipe includes a pre-drilled and tapped 1/8” NPT port for convenient Water/Methanol Injection nozzle installation, along with a properly placed bung for the OEM Manifold Absolute Pressure (MAP) sensor. Unlike its competitors’, Unitronic’s Charge Pipe Upgrade Kit includes all the OEM wiring harness mounting points, to avoid wiring harnesses from dangling within your engine bay or having to zip-tie them manually.


Like all Unitronic Performance Hardware, these new Intercooler and Charge Pipe Upgrade Kits include all necessary hardware and offer direct bolt-on fitment, which retains the factory mounting locations in order to simplify the installation process.
