Wagner Tuning Radiator Kit for G29 BMW Z4 / A9x Toyota GR Supra (OPF)

The Wagner Tuning Radiator Kit for the G29 BMW Z4 and A9x Toyota GR Supra is engineered to significantly improve cooling efficiency for vehicles equipped with the B48 2.0L I4 turbo and B58 3.0L I6 turbo engines. Designed as a competition-grade water cooler upgrade, this kit increases overall cooling volume by an impressive 117%, helping dramatically reduce coolant temperatures and stabilize thermal performance under sustained load. By maintaining more consistent operating temperatures, the system supports reliable power delivery during spirited driving, track use, or high-performance tuning, making it an essential upgrade for owners seeking maximum, repeatable performance from their OPF-equipped G29 and A9x platforms.

Why the Wagner Tuning Radiator is the Best Choice for Your B58

Record-Breaking Volume Expansion: Wagner Tuning equips the Competition racing water cooler with an intercooler core that increases total cooler volume by an impressive 117% compared to the factory unit (16.70 liters vs. 7.70 liters OEM).
Direct Performance Boost: Wagner Tuning’s design lowers coolant temperatures within the indirect intercooler circuit, improving charge-air cooling, stabilizing overall system thermodynamics, and helping prevent heat-related power loss.
Maximum Heat Transfer: Wagner Tuning optimizes the ratio between internal and external cooling surfaces to ensure maximum heat dissipation while maintaining sufficient airflow for surrounding components.
Durability & Protection: The cooler is finished with a heat-conductive, anti-corrosion coating to deliver long-lasting, reliable cooling performance.
Plug & Play Installation: Wagner Tuning designs the kit for straightforward, near plug-and-play installation, supported by clear and user-friendly instructions.
Technical Detail: Wagner Tuning engineers the cooling circuit specifically to optimize performance for B48 and B58 engines.
- Wagner Tuning notes that the 2.0L B48 and 3.0L B58 turbo engines used in the BMW Z4 G29 and Toyota Supra A90 / A91 rely on an indirect intercooler system, where charge air is cooled via a dedicated coolant circuit. Reducing coolant temperature is therefore critical to improving charge-air efficiency.
- The Wagner Tuning upgraded water cooler addresses this limitation with a 117% increase in volume, allowing the coolant to remain at lower temperatures for longer periods. This is especially important for high-performance vehicles and OPF-equipped models that experience increased thermal stress.

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.
