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.

Knock down the roadblocks preventing you from performing regular maintenance on your BMW. On the E9x and E8x chassis you run into issues with changing the rear spark plugs and coil packs. A job that should take approximately an hour or so ends up taking significantly longer because you have to remove the cowl and all associated screws. Most of the time the screws end up missing or dropped into your engine bay which can be a headache and you have to order new hardware or deal with the cowl being incorrectly fastened.
Cowl delete filters are a great addition to your E9x or E8x chassis; these filters allow you to get rid of clutter in the engine bay which adds benefits like weight reduction, improved air flow in the engine bay, more room for working on the engine and an overall cleaner engine bay appearance. We all know it is important to keep up on engine maintenance to keep your BMW running at peak performance and prevent larger future issues. When we can eliminate any roadblocks or additional work preventing us for performing engine maintenance this could make it less daunting to go change spark plugs, coil packs or simple filters.
Benefits:
Weight Reduction
Cleaner engine bay appearance
Added room for maintenance
Improved engine bay air flow

The transmission is sometimes neglected during regular vehicle maintenance over time. Without proper servicing, the automatic transmission fluid can deteriorate, resulting in contamination of the valve body and filter with deposits and sludge. This can cause issues like rough shifting, slipping, and, in severe cases, necessitate transmission replacement.
For a reliable replacement transmission filter, consider Febi-Bilstein for top-notch quality.
