Rotrex C38 Prima Kit (Non-Intercooled).

The Active Autowerke Prima supercharger kit has gained a reputation as one of the finest and most affordable systems available for the E46 BMW M3. Capable of exceeding 500 WHP through Level 1 and Level 2 upgrades, PRIMA is a star performer.

This supercharger system was designed with no frills in mind – instead focusing on the pure and basic fundamentals. PRIMA is a fully bolt-on non-intercooled system that is completely reversible and Does Not require any custom fabrication. For those who desire some extra horsepower, the PRIMA system is fully upgradable via Level 1 and Level 2 options. With an outstanding design synonymous with the Active Autowerke brand, we have made our finest forced-induction kit even more affordable; all while maintaining the inherent driver-centric qualities of the BMW M3.

                                                Returns Policy

                                                If a product is ordered and not wanted, the UNUSED item can be returned for a 25% restocking fee unless otherwise specified. In some cases, we may offer the ability to return the item to us for a lesser restocking fee and then keep the balance as a store credit. To return an item, it must be in brand new condition with original packaging.

                                                We cannot accept a return on special ordered or custom items.

                                                Shipping is non refundable in either direction unless approved by AutoTalent. All items wanting to be return MUST be reported within 30 days of the original invoice date. No items will be returnable after 30 days. All products shipped from the AutoTalent facility are shipped via FedEx, USPS, or USPS. Some packages shipped from the manufacturer may or may not require signatures for package release.

                                                Special Order Items

                                                Some items may be special order specifically for the customer’s vehicle. These items generally require a deposit or paid in full. Once this deposit amount is notified to the customer and they agree to order the special order item, the deposit becomes non-refundable. These special order items cannot be returned or resold. Cancellations are not allowed on special order parts.

                                                AutoTalent DOES NOT REFUND SHIPPING CHARGES. If you modify, install, or alter the item in any form, we cannot accept it as a return. We will not cover any expenses related to the product or installation, and you may be required to purchase a replacement.

                                                ** All cancellations that are requested that are NOT due to items not being in stock or delayed by the manufacturer are subject to a 5% processing fee. When you place an order with us we pay credit card fees that are NOT returned back to us. We will absorb these fees if we do not have the item in stock OR if you agree to the original ETA and that ETA is NOT met. If you decide to cancel for any other reason you will not receive this 5% fee back

                                                When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.
