2.0 TSI Intake Manifold
Featuring better flow, higher boost capacity, and integrated flapper delete; this manifold will take your car to the next level. A direct bolt-on replacement for your OEM plastic intake manifold, HPA's performance manifold features a 40% increase in volume over the OEM plenum, and its cast aluminum construction supports larger turbos and higher boost resulting in big potential performance gains.
HPA's performance intake manifold is powder coated with a satin-black finish for durability and greater heat dissipation.
* Note: this is an aftermarket manifold that may not be certified to meet your local emissions regulations.

2.0 TSI K04 Turbo Upgrade
HPA’s Borg Warner K04 Turbo (equipped on the Golf R / S3) is a much more robust turbo with a higher operational boost range. HPA modifies the OEM K04 compressor cover, to allow the factory K03 diverter valve to be installed in the OEM location via a CNC port adapter. This allows for seamless integration of the factory TSI IHI (K03) plumbing, simplifying the installation for shops and home mechanics alike.
HPA also removes the turbo muffler to accommodate a specialized CNC-machined fitting, allowing the outlet pipe of the turbo to be rotated to clear the block. This increases airflow exiting the turbo. A laser-cut block off plate for the OEM S3 PCV system is included with all K04 kits as this port is not required on a TSI motor.
Each kit includes a TSI Stage 2 software tune, as developed on our winning SCCA World Touring Car engines, allowing for maximum horsepower, drivability and engine longevity.

TSI Street Downpipe
The HPA TSI Downpipe optimizes back pressure and allows our calibrators the headroom to maximize both power and torque.
The resulting 3” downpipe is a fabrication assembly designed around functionality and durability. .063wall T304 stainless mandrel tubing is precision tig welded for an ultra clean look. Our CNC formed hanger and laser cut flanges mate this assembly to the chassis and will withstand the thermal conditions the turbo will generate. Our flex couplings feature an internal stainless steel interlock liner that facilitates smooth flow of high temperature exhaust gases.
HPA street downpipes come standard with our 100C high flow cats, the same cats used on all HPA twin turbo vehicles.
A race (catless) version of this downpipe is also available upon request.
Additional details on HPA's TSI Downpipes can be found here.
Mk5/6 Street Intercooler
Precision machined, this direct fit Intercooler will optimize intake temperatures for your tuned engine, while its 50mm thick bar and plate cooler core will only minimally impact airflow over your radiator.
A special heat expelling coating has been applied to the cast aluminum end tanks to optimize this package.
Additional information on HPA's Mk5/6 Street Intercooler can be found here.
TSI ECU Programming
The HPA methodology of performance programming involves utilizing the adaptive environment of the factory VW/ Audi programming which is capable of analyzing and reacting to changes in fuel, temperature, air flow, etc.
Rather than creating a tune with fixed variables that overwrites the built in factory safety nets as most tuners do, each HPA tune is custom calibrated per vehicle using the factory Hex and A2L files.
Working in-house on a state of the art Superflow all-wheel drive rolling road simulator, the team at HPA runs each calibration set through a series of rigorous evaluations ensuring maximum performance is realized while all safety limits are in tact.
TSI Stage 1 Tune
For tuning requirements beyond Stage 1, contact HPA directly for pricing and performance results.
