Maintaining proper oil levels in your engine is crucial for peak performance. Undetected leaks can cause your oil to drop to dangerously low levels between oil changes, leading to severe engine damage.

One common culprit for oil leaks is the valve cover. Over time, exposure to extreme temperature fluctuations can wear down the gaskets, causing them to fail. Prevent oil leaks and protect your engine by replacing these vital components.

Comprehensive Kit Includes:

Valve Cover Assembly Valve Cover Gaskets Gasket Flange CCV Hose Hardware Replace your old gaskets with our high-quality kit to keep your engine running smoothly and efficiently.

Upgrade your stock oil cooler thermostat for improved performance. Swap your factory 110-degree Celsius thermostat for a new 70-degree Celsius version for faster oil flow and extended temperature control. With oil temperatures reaching 230 degrees Fahrenheit by the time your factory thermostat opens, initiating oil flow at lower temperatures proves more effective than attempting to cool down already elevated temperatures.

Utilizing a factory-style thermostat, this upgrade can be used in all weather conditions and allows your engine to warm up properly, unlike thermostat bypass kits.

Kit contents:

Lower temperature thermostat - 70c (158F) vs Factory 110c (230F)
Low temp thermostat spring

Every 60-80,000 miles, we recommend replacing your spark plugs to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced. Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty. As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

BMW has a seemingly endless number of fans of the N54/N55/S55 engines, three straight-six turbo engines that are each capable of 750+ horsepower, but that doesn't mean they were without their faults! BMW's N54 had a notoriously rocky start with reliability due to multiple issues such as fuel injectors failing, turbos failing, serpentine belt failure, crank hubs coming loose, and more... BMW made multiple attempts to fix the issues plaguing the N54, but they could only do so much and the fixes rolled out seemed temporary at best. Following the N54, BMW released their updated N55 and S55 engines, giving many people hope that these engines would address the previous issues. Unfortunately, this was only some-what the case. Crank hubs and crank bolts continued to loosen over time and serpentine belts continued to shred themselves and get pulled into the oil pan through the front main seal. For all three engines, this meant a single failure could effectively turn your engine into an oversized paperweight. Luckily for us, the BMW community is full of skilled enthusiasts who have gladly taken up the task to offer solutions! The first headache to be addressed was the Crank Hub and Bolt. Using a simple plate that fits perfectly over your crank hub's hex-head bolt and mounts up against the damper, the crank bolt is effectively locked in place, preventing it from being able to back out until the plate is fully removed. Next up was the serpentine belt failures. It's not known what exactly causes the serpentine belt to split, but once it does, the pieces hanging off of the belt wrap around and behind the damper. This leads to the belt breaking up into smaller pieces and eventually getting pushed between the crank hub and rear main seal into the oil pan. These small pieces of debris get caught in and block the oil pickup, preventing oil flow and leading to engine failure. To prevent this, multiple aftermarket companies came up with their own versions of Crank Seal Plates. This plate is installed behind the front damper, blocking the opening that allows the serpentine belt to pass between the crank hub and seal, keeping debris out of your oil pan! Also included in this kit are the components to service your front Oil Cooler/Filter Housing gaskets, refresh your drive belt system, and install the aftermarket upgrades. Kit Features and Contents: Vargas Turbo Crank Bolt Capture Vargas Turbo Crank Seal Plate OEM Accessory Belt OEM Belt Tensioner & Idler Pullies Liqui-Moly Longtime High Tech Engine Oil (5w-30) - 7 Liters OEM Hengst Oil Filter OEM Oil Filter/Cooler Housing Gaskets TMS Oil Change Sticker Genuine BMW Full-Strength Coolant - 1 Liter Looking to go even further and upgrade your Crank Hub as well?

When it comes to optimizing the performance and longevity of your BMW N55 or S55 engine, few upgrades can rival the impact of replacing the camshaft, bearings, and gaskets. These essential components play a pivotal role in your engine's overall health and performance, and upgrading them can deliver a host of benefits, from increased power to enhanced reliability. In this article, we'll explore the advantages of investing in these critical upgrades for your BMW N55 or S55 engine. Improved Performance: Upgrading your BMW N55 or S55 engine with a new camshaft can significantly boost its performance. A high-quality camshaft can optimize valve timing, leading to improved airflow and combustion efficiency. This, in turn, results in increased horsepower and torque, providing you with a more exhilarating driving experience. If you're seeking that extra punch when you hit the gas pedal, a new camshaft is the way to go. Enhanced Durability: The camshaft, bearings, and gaskets are fundamental components of your engine's internal structure. Over time, wear and tear can cause these parts to degrade, potentially leading to catastrophic engine failure. By replacing these components with high-quality, performance-oriented alternatives, you're not only increasing horsepower but also reinforcing the engine's durability. This can help prevent costly breakdowns and extend the life of your BMW engine. Optimal Efficiency: Efficiency is a key factor in engine performance. Worn-out bearings and gaskets can lead to oil leaks and reduced engine efficiency. Replacing them ensures a tighter seal, minimizing oil leaks and maintaining the proper lubrication for all moving parts. This leads to better fuel efficiency and a smoother, more reliable engine operation, all while reducing maintenance costs in the long run. Increased Resale Value: Investing in high-quality components like camshafts, bearings, and gaskets not only enhances your driving experience but also adds value to your BMW. When it's time to sell or trade-in your vehicle, potential buyers or dealerships will recognize the value of these upgrades, making your car more desirable and potentially increasing its resale value.
