This condition applies to the following product categories:

• Suspension
• Engine Tuning
• Engine Parts
• Exhaust Systems
• Fueling
• Turbochargers/superchargers
• Drivetrain
• ECE-approved Downpipes

All of the above products are manufactured or sourced individually based on the customer’s order, and therefore cannot be returned after delivery, unless the product has a manufacturing or material defect.

Bolt-on kit. Compatible with the original exhaust manifold, intake, and charge pipes.

If you want to receive new turbos in advance before returning the old ones, choose the option without the core charge (Stage 1, €2044 / Stage 2, €2663). Once the manufacturer has received the stock turbo cores and approved them, the core charge portion (€743) will be refunded to you.

Note! During the peak season, sending your own turbos to the manufacturer for an update is faster, ensuring that you receive the updated turbos as quickly as possible.
