The ZF 8-speed automatic transmission (8HP) has become the go-to choice for performance enthusiasts, delivering lightning-fast shifts, impressive torque handling, and ample tuning potential. However, the stock transmission pan falls short in critical areas. Its plastic construction, integrated non-replaceable filter, and limited fluid volume leave little margin for error in demanding conditions.

To address these limitations, we've engineered a premium solution: a cast aluminum transmission pan that boosts durability, cooling performance, and serviceability. Designed with enthusiasts in mind, this upgraded pan increases fluid capacity by 1 liter to reduce transmission temperatures and improve long-term reliability, even under aggressive driving or track conditions.

Built to outlast and outperform the OEM plastic pan, the aluminum construction resists damage from road debris and eliminates the risk of cracking. Our pan is hard-coat anodized in black for superior corrosion protection and a long-lasting finish that looks as good as it performs.

Our aluminum pan upgrade is engineered to work seamlessly with the OEM G8X 8HP transmission filter (24007855263), allowing for easy and cost-effective fluid service. Integrated magnets help to trap metal particulate, extending the life of your transmission by keeping contaminants out of the fluid.

Key Features:

Cast aluminum construction offers superior strength and resilience over the OE plastic pan

Increased fluid capacity (+1L) enhances thermal management and reduces the risk of overheating

Serviceable design uses the OEM G8X transmission filter for easy, affordable maintenance

Hard coat anodized finish provides exceptional corrosion resistance and longevity

Integrated magnets collect metallic debris, protecting transmission internals

Kit Includes:

Turner Motorsport ZF 8HP High-Capacity Aluminum Transmission Pan
OE Hengst G8X Filter Installation Kit
Installation:

Vehicle plastic belly pans may vary. Because the Turner 8HP transmission pan is taller to allow for increased fluid capacity, some vehicles may require trimming of the plastic belly pan, or the belly pan may need to be installed over the transmission pan where it may make contact.

Upgrade your BMW's performance with Turner Power Pulleys, designed to enhance engine efficiency and increase available horsepower.

By the early 1990s, BMW had phased out its canister-style ignition coil in favor of an individual coil-on-plug system. The venerable M50 was one of the first engines to receive this update, which boasts greater overall efficiency through increased ignition control and spark energy. Unfortunately, over two decades later, the ignition coils used on the M50, M52, S50, and S52 engines are antiquated at best. Our team of engineers and BMW enthusiasts realized the need for an ignition system upgrade and set out to modernize the M5X ignition system with performance ignition coils pulled from the B58 parts bin.

WHY UPGRADE?

B58 ignition coils provide up to 2.5 times more spark energy than OE M5X ignition coils, effectively eliminating misfires even on high-performance setups. Whether your vehicle is heavily modified or completely stock, these ignition coils deliver unparalleled performance with zero downsides! For tuners, the Turner Motorsport kit also allows for precise adjustments to ignition dwell time through standalone engine management, giving you complete control over your engine’s performance.

Our kit utilizes the factory mounting locations and includes a proprietary boot design with a built-in 1k OHM resistor. Unlike many aftermarket options, our design prevents electrical contact springs from burning out, ensuring long-term reliability and durability. The included ignition coil bracket and cover plate are manufactured from durable 5052 aluminum, combining rugged durability with a premium aesthetic. Designed and optimized in-house using cutting-edge 3D scanning hardware and CAD software, our kit ensures a perfect fit and a clean, factory-like appearance. Installation is a breeze with the included adapter harness, allowing you to add modern ignition coils to your M5X with ease!

Eliminate misfires and unleash the full potential of your M5X-equipped BMW with our industry-leading B58 ignition coil upgrade. Designed for easy installation and unparalleled reliability, it’s the ultimate plug-and-play solution for performance enthusiasts.

FEATURES:

B58 ignition coils offer upwards of 2.5x more spark energy than the OE M5X ignition coils Eliminates common ignition system defects - no more chasing misfires or swapping around coil packs! The included brackets, cover plates, wiring harness adapters, and proprietary boots make for an easy installation Confirmed functionality with factory M3.3.1 (OBDI) and MS41 (OBDII) DME software PART DESIGN:

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
