Turner Motorsport CSL Style Intake Kit – BMW E46 M3 6MT – Matte

The Turner Motorsport CSL Style Intake Kit brings the legendary E46 M3 CSL-inspired airbox design to the BMW E46 M3 S54 with 6-speed manual transmission.

Turner optimized the CSL-style design to provide approximately 20% more airflow than the factory E46 M3 airbox, along with the distinctive high-performance induction sound associated with the CSL.

Key Features:

• Designed for BMW E46 M3 S54

• 6MT / Manual Transmission

• CSL-style airbox design

• Matte finish

• Approx. 20% increased airflow over the factory airbox

• Iconic CSL-inspired induction sound

• Complete conversion kit, excluding tuning

Note: US-spec vehicles produced 09/2004 and later require modification and reuse of the factory PCV recirculation hose to retain proper PCV functionality.

Special Orders

Most products sold by 811 Motorsport are considered special-order items and are ordered specifically based on the customer's request.

For this reason, returns, exchanges, or cancellations are not accepted unless the product has a confirmed manufacturing defect, arrives damaged, or an incorrect product was supplied.

Customers are responsible for reviewing their order details and product specifications carefully before completing their purchase.

Return Condition

Any product approved for return must be unused, uninstalled, and in the same condition as received.

The product must be returned with its original packaging, labels, accessories, manuals, and all included items.

Products that have been installed, used, modified, damaged after delivery, or returned without their original packaging may not be eligible for return or refund.

Approved refunds are generally processed within 5–10 business days after final confirmation. Additional processing time may apply depending on the customer's bank or payment provider.
