What do BMW S58 turbo inlet elbows actually improve?

The factory S58 inlet geometry introduces restrictions before the turbo compressor inlets. The MMX BMW S58 turbo inlet elbows replace this with constant-diameter 6062-T6 aluminum tubing and an integrated velocity stack that keeps airflow laminar all the way to the compressor housing, resulting in faster spool, improved throttle response, and more consistent airflow under high-boost conditions.

Do these work with the stock intake or do I need an aftermarket intake?

The MMX S58 turbo inlet elbows are compatible with the factory OEM intake pipes, the MMX Intake Pipe Set (MMR11-1601), and most popular aftermarket intake systems. No intake upgrade is required — they work as a standalone bolt-on.

Do the BMW S58 turbo inlet elbows fit all G8x variants?

Yes. The kit fits the G87 M2 (2023-present), G80 M3 Sedan (2021-present), G81 M3 Touring (2022-present), G82 M4 Coupe (2021-present), and G83 M4 Convertible (2021-present) — all S58-powered G8x models.

How difficult is installation?

The MMX turbo inlet elbows are a direct-fit bolt-on upgrade. All necessary hardware is included in the kit. Level-2 install difficulty applies due to turbo bay access, but no cutting, drilling, or fabrication is required.

Are these suitable for modified or tuned S58 builds?

Yes. The elbows are designed for both stock and modified G8x platforms. The robotically TIG-welded construction and constant-diameter tubing maintain strength and flow consistency under elevated boost pressures, making them suitable for tuned applications.

Description

MMX Turbo Inlet Elbows for G8x BMW M2 / M3 / M4

BMW S58 turbo inlet elbows from MMX Performance are a direct-fit airflow upgrade for the S58 3.0L twin-turbo engine in the G87 M2, G80 / G81 M3, and G82 / G83 M4, developed after extensive Nürburgring testing on the MMX G87 M2 demo car. The factory inlet geometry is a known restriction; these elbows replace it with mandrel-bent 6062-T6 aluminum tubing in constant 70mm and 63mm outer diameters, eliminating the bottlenecks in the OEM setup and feeding the turbos with unrestricted, laminar airflow. An integrated velocity stack at the inlet further promotes smooth airflow into the compressor housing, improving spool speed and throttle response. Every component is CNC-machined, mandrel-formed, and robotically TIG-welded for precise fitment and consistent strength under high-boost loads. Finished in MMX Titanium with a hand-polished surface and laser-etched branding, the kit is fully compatible with OEM intake pipes, the MMX Intake Pipe Set, and most aftermarket intakes.

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.
