Check the make, model, generation, year, engine, power and transmission listed on the product page. Then compare the manufacturer’s part number. If in doubt, send us your VIN, engine code and a list of existing modifications before ordering.

Not necessarily. ECU tuning, a different turbo, an existing exhaust system, a change in diameter, larger brakes, a specific suspension setup or bodywork components can affect fitment and installation. Each modified configuration must be checked individually.

Only the documentation for the exact part number can confirm this. A CE, ECE or TÜV designation may relate to a specific application and configuration. A decat part, a part without road approval or a motorsport part must be reserved for permitted uses, particularly on a track.

Depending on the part, new seals, bolts, clamps, adapters, hoses, mounts, sensors, wheel alignment or electronic adjustments may be required. Follow the manufacturer's instructions and use a professional experienced with modified vehicles.

Some parts work without calibration; others require an ECU adjustment for safety, reliability or the intended performance. Intake systems, downpipes, turbos, injectors and major cooling changes should be assessed with your tuner.

Standard delivery throughout the European countries we serve generally takes 3–5 business days after order processing. Made-to-order, configured or specially sourced parts may take longer. Express delivery is not available.

No. Returns are accepted within 14 days only for new, complete, unfitted and unmarked parts in intact original packaging. Return shipping is paid by the customer. Trial fitting that leaves marks, installation or damaged packaging may lead to refusal.

Use the Contact page and include the product link or part number, your VIN, engine code, power, year, transmission and existing modifications. The more thoroughly the configuration is documented, the more precise the check can be.
