Introducing our Turner Motorsport Crank Seal Guard – the essential shield for your BMW's engine integrity. Safeguarding the heart of your vehicle, this meticulously designed guard offers robust protection for the crank seal concealed behind the harmonic balancer.

Considered an indispensable maintenance component for your BMW, the Crank Seal Guard acts as a crucial defense against a potential and preventable catastrophe involving your accessory belt. Facing the reality of potential oil or coolant leaks in your engine, this guard becomes a reliable barrier, preventing these fluids from reaching the accessory belt. The consequence of a compromised belt includes walking, slipping, fraying, and rubber particles finding their way behind the harmonic balancer and into the crank seal – a scenario that can lead to severe engine failure.

Let's be honest, engine leaks are a common occurrence, and whether your engine is currently leaking or not, the Crank Seal Guard is a proactive measure against future threats. The wear and tear on the accessory belt due to oil and coolant exposure can result in slipping, tearing, or, worst-case scenario, belt snapping – posing a significant risk to your engine's well-being.

Prepare your car for the long haul and protect the vital components, It's not a matter of "if" but "when" your belt will become a problem, and our Crank Seal Guard is your proactive solution. Rigorously tested on N52/N54/N55 and S55 for 100% confirmed fitment, it stands as a reliable guardian for your engine's health. Invest in the protection your BMW deserves with the Turner Motorsport Crank Seal Guard.

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

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.

This is an OEM INA Idler Pulley, also known as the roller pulley or deflection pulley. The idler pulley is known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).
