TTE550 Turbochargers start life and evolves from Genuine RS4 K04 OE units that are Engineered. These units offer you more performance yet offer near no loss in response over stock K04 once tuned with correct hardware & software. Very popular with owners wanting RS4 plug & play fitting units but with greater and wider performance to over 550PS but still keeping OEM drivability.


Precisely balanced turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes, then components are assembled and then the CHRA are dynamically balanced, but this time depending on application at up to 250,000 RPM in multiple planes using TTE's in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with serial numbered balance test result document.

Note: These turbochargers use K04 RS4 B5 compressor housings with 58mm inlets. Specific turbo intake pipes to suit are required . The turbine housings are RS6 C5 specific, so flange on downpipe is needed to match. They do not work with RS4 B5 specific downpipes but these can be adapted with use of a RS6 flange.
