When it comes to serious performance driving, the stock BMW G2X radiator quickly shows its limits. Like many factory BMW cooling systems, it relies on molded plastic end tanks that are notorious for cracking and leaking over time. Additionally, its single-row, 34mm-thick core offers poor cooling capacity for high-horsepower or track-driven cars.

To address these shortcomings, ECS developed the ultimate cooling solution for the G2X B58 platform�a High-Performance Aluminum Radiator designed, engineered, and tested by their in-house BMW specialists. Built to handle the increased thermal demands of high-horsepower builds and extended track sessions, this radiator delivers both unmatched durability and significantly improved heat dissipation.

Each unit features fully TIG-welded 6061-T6 aluminum end tanks, eliminating the weak points found in the OE design. Precision CNC-machined hose connections, flanges, and mounting brackets ensure a perfect drop-in fit with factory hoses, the fan shroud, and auxiliary components. No modifications required � just direct performance.

At the heart of the design lies a dual-row, 42mm-thick core, increasing total coolant volume and surface area for improved heat transfer. Compared to the factory�s 34mm single-row core, this upgrade translates to cooler operating temperatures and consistent performance under demanding conditions.

Features:

Full 6061-T6 aluminum construction eliminates plastic end tank failures Dual-row, 42mm performance core (45% thicker than OE) for increased cooling efficiency OE Radiator: Single-row, 34mm core ECS High Performance Aluminum Radiator: Dual-row, 42mm core TIG-welded aluminum end tanks for maximum strength and longevity Polished finish for a premium appearance CNC-machined fittings and brackets ensure seamless compatibility with factory hoses, transmission cooler lines, and condenser Direct-fit installation � no cutting or modifications required Replaces OEM Part Numbers: 17118666740, 17115A30677

Maximize cooling efficiency and take your BMW’s performance to the next level with the ECS High Performance Cooling System Bundle—a complete, track-proven upgrade engineered to handle the extreme thermal demands of the G2X B58 platform. Developed by the enthusiasts at ECS Tuning, this system includes both the High Performance Aluminum Radiator and High Performance Aluminum Heat Exchanger, designed to deliver consistent, reliable temperature control in even the most demanding driving conditions.

The factory BMW cooling components just aren’t built for high-performance or track use. Both the OE radiator and heat exchanger feature weak plastic end tanks and undersized single-row cores—common failure points when exposed to elevated heat and pressure. ECS set out to solve these shortcomings with an all-aluminum, dual-row system designed for enthusiasts who demand more from their BMW. ECS engineers started by replacing the fragile plastic end tanks with TIG-welded 6061-T6 aluminum for unmatched durability. Each tank is precision-crafted with CNC-machined billet aluminum hose connections, flanges, and brackets, ensuring direct OE-style fitment with the factory hoses, fan shroud, and accessories—no cutting or modifications required.

Both the radiator and heat exchanger feature high-capacity, dual-row 42mm cores, a massive improvement over the factory’s 34mm and 25mm single-row designs. The result? Faster heat dissipation, lower intake air temperatures, and more consistent performance, whether you’re cruising or carving apexes.

Radiator: Replaces OEM part numbers 17118666740 and 17115A30677

Heat Exchanger: Replaces OEM part numbers 17118666811 and 17115A54040

Features:

6061-T6 aluminum construction eliminates weak plastic end tanks Dual-row core design for increased cooling capacity and efficiency Radiator: 42mm dual-row core (45% thicker than OE 34mm core) Heat Exchanger: 42mm dual-row core (72% thicker than OE 25mm core) TIG-welded end tanks for superior strength and reliability Polished aluminum finish for a premium, high-performance look CNC-machined connectors and brackets for perfect OE fitment Fully compatible with factory hoses, fan shroud, condenser, and intercooler Direct bolt-in installation—no modifications required

GA8HP 8 speed automatic transmission. Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This item fits the following BMWs: E71,E89 Z4,F06,F10,F12,F13,F15,F16,F22,F25 X3,F26 X4,F30,F31,F32,F33,F34,F36

BMW claims their transmission fluid to be a "lifetime" fluid, however is recommended to be changed every 60,000 miles to ensure a longer transmission life. Though not exposed to the same level of heat and contamination as engine oil, transmission oil still breaks down over time due to heat and becomes contaminated as your transmission wears. Old contaminated oil can lead to excessive wear and tear on sensitive transmission components which could lead to slow shifting, slips, and even complete failure. This is also true for the transmission filter integrated into the transmission fluid pan. The filter removes metal particles from the transmission fluid and eventually begins to clog, preventing fluid from passing through the filter easily. This leads to excessive wear and a reduced transmission lifespan if not changed. This high-quality Meyle transmission pan includes a new filter and is quintessential for a correct and full service.

Paradigm Engineering’s B58 oil filter housing cap directly augments your vehicle's oil filtration system and serves as a diagnostic tool. Each B58 oil filter cap is CNC milled from a solid block of billet aluminum and fitted with a Nickel plated neodymium rare earth magnet. This magnet is in direct contact with pre-filtered oil, as a result, the magnet will naturally capture Ferrous particles within your engine oil. Ferrous particles in engine oil cause premature wear, obstruct the paper oil filter and could be an indication of a serious issue within your engine.

Dinan Iridium Spark Plugs are an excellent upgrade for tuned, and even stock engines. Our spark plugs are made from Iridium - one of the strongest materials available. They last longer than other materials with higher melting points, run cooler, resist preignition, and even require less voltage to produce a strong spark. The iridium electrode with its copper core is harder and stronger than other materials, can dissipate heat more easily, and is better protected from melting, cracking, and other limitations found with standard plugs. Dinan spark plugs are great for high boost, high cylinder pressure, high cylinder temperatures, and high-power situations, and they pair nicely with a set of Dinan ignition coils, where applicable. However, they are not only for tuned and higher output vehicles that may benefit from a plug cooler than the factory heat range - they also are applicable to non-tuned / stock vehicles as well! The D640-0003 spark plug applies to the following engines: B48 TU B58 TU2 (Gen 2 B48 Gen 3 B58)
