Which configuration should I choose for the Eventuri Hybrid Carbon Airbox System, and do I already need an Eventuri intake?

Configuration selection is required before ordering. Choose the full system (part number EVE-E46ABX-CF-INT) if you are upgrading from the factory airbox and need the complete intake, filter housing, and cold-air scoop. Choose the airbox-only option (EVE-E46ABX-CF-PLM) if you already run an Eventuri intake and want to reuse your existing filter housing and scoop.

Does the Eventuri Hybrid Carbon Airbox System require an Alpha-N conversion or ECU tune?

No. The Eventuri Hybrid Carbon Airbox System retains the OEM MAF sensor through a CNC-machined MAF boss in the snorkel, so it runs plug-and-play with no Alpha-N MAFless conversion, remap, or ECU recalibration. This preserves factory throttle response and drivability while still producing the signature CSL-style induction sound under load.

Will this fit my E46 M3, and does it work with SMG transmissions?

Yes. The system fits the BMW E46 M3 (2001-2006) with the S54 engine, in both LHD and RHD, and works with manual and SMG cars. SMG owners should note a relocation requirement: Eventuri recommends the BMW M3 CSL OE SMG fluid reservoir and bracket, which is standard practice for CSL-style airbox installs on SMG vehicles.

What is the Eventuri Hybrid Carbon Airbox System made from and how durable is it?

The system is manufactured from 100% prepreg carbon fiber, autoclave cured, and assembled with CNC-machined hardware and stainless steel reinforcement rings on the six intake trumpets. Stainless mounting brackets, CNC-machined breather adapters, and a custom EPDM coupler with silicone hoses give the system OEM-level fitment and long-term durability through repeated heat cycles and vibration.

What replacement filter does the intake housing use, and can I return the airbox?

The intake housing (full system only) uses one replacement filter, part number EVE-661-G2-FTR. This item is not eligible for return. Warranty coverage and damage-in-transit support are fully provided, so any transit damage or covered defect is handled directly.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
