At we have addressed all the well known problems related to the U.S single vanos engines and provided solutions to those problems in a complete, ready to install kit. Each vanos is fully rebuilt using modified bearings to eliminate the dreaded rattling noises, then high-performance Teflon seals and Viton O-rings are installed to restore lost power and increase the life of the unit. Our vanos units will stand up to more abuse making them ideal for street/track cars, race cars, and forced induction applications.

The Single Vanos comes as a fully rebuilt vanos unit with modified bearings to eliminate the dreaded 'Vanos Rattle'. Every vanos also comes with new high-performance Viton O-rings and Teflon seals installed to restore lost power and improve gas mileage... two solutions in one package!

The Stage I Vanos price includes a fully refundable $100 deposit. You can return your old vanos to us using the supplied UPS return label in the box and we will refund your $100 deposit to you within 1-2 business days for a net price of $275.

The Stage II kit adds REM coated cam gears and thrust washers which will further reduce chain noise and cut down on friction, allowing the vanos to work with less effort. This is a great upgrade for any car that sees more than the typical daily commute, and will stand up to the abuses of Auto-x and Club Racing or Forced Induction applications.

The Stage II Vanos price includes a fully refundable $200 deposit. You can return your old vanos to us using the supplied UPS return label in the box and we will refund your $200 deposit to you within 1-2 business days for a net price of $400.

If you are using high profile race cams, such as the Sunbelt cams, then we can add a shim to limit vanos travel adding a margin of safety to the valves at very high RPM's. We offer a standard (Small) shim for mild race cams and a thicker (Large) shim for more aggressive cams. The limiter is NOT recommended for stock cam profiles as it will reduce overall torque at lower RPM's.

The German Auto Solutions 1.2 bar Cooling System Cap uses 100% original BMW internal components that have been recalibrated to vent at 1.2 bar vs. the factory 2.0 bar setting. Most modern cooling systems are calibrated at 1.0 - 1.2 bar to reduce stress on the plastic components, increasing the lifespan of the fragile plastic parts without affecting the performance of the cooling system. The top of the cap is CNC machined from 6061 aluminum, hard anodized black to prevent corrosion, and then laser etched so it looks cool.
