Review BMW 1703890/1703891 Used Intake And Exhaust Cams fits 328I 528I E34 M50 E36 M52

The BMW intake and exhaust camshafts, specifically part numbers 1703890 and 1703891, are designed for various BMW models including the 328i, 528i, E34 M50, and E36 M52. These camshafts are essential components of the engine's valvetrain system, responsible for controlling the timing and duration of the intake and exhaust valves.

The intake camshaft (part number 1703890) plays a crucial role in delivering air and fuel mixture into the engine's cylinders. Its precise design allows for optimal intake valve timing and duration, ensuring efficient combustion and improved engine performance. The camshaft is made of durable materials to withstand the extreme temperatures and pressures within the engine, while its hydraulic roller bearings ensure smooth and quiet operation.

The exhaust camshaft (part number 1703891) is responsible for controlling the timing and duration of the exhaust valves. Its design optimizes exhaust gas flow, reducing backpressure and improving engine performance. Like the intake camshaft, the exhaust camshaft is made of high-quality materials and features hydraulic roller bearings to ensure long-lasting, smooth operation.

These BMW intake and exhaust camshafts are perfect for BMW enthusiasts looking to enhance the performance of their engine. They offer numerous benefits, including improved throttle response, increased power output, and smoother engine operation. Additionally, they are a cost-effective solution compared to a full engine build or other performance upgrades.

When installing these camshafts, it is essential to follow the manufacturer's instructions carefully and use the appropriate tools and equipment. Proper installation is crucial to ensure the camshafts function correctly and do not cause any damage to the engine or other components.

In summary, the BMW intake and exhaust camshafts (part numbers 1703890 and 1703891) are essential components for optimizing engine performance in various BMW models. They offer numerous benefits such as improved throttle response, increased power output, and smoother engine operation. Made of high-quality materials and featuring hydraulic roller bearings, these camshafts are built to last and provide reliable performance for BMW enthusiasts looking to enhance their engine's capabilities.

Buying BMW intake and exhaust cams for the E34 M50, E36 M52, 328i, and 528i models can offer several potential benefits. These upgrades can lead to increased horsepower, improved torque, and enhanced engine performance. However, there are also some drawbacks to consider.

1. Power Gain: Upgrading the intake and exhaust cams can result in a noticeable increase in power delivery, making the engine feel more responsive and lively.

2. Improved Engine Sound: The intake and exhaust cams can alter the engine's sound, often producing a more pleasing exhaust note and enhancing the overall driving experience.

3. Durability: BMW OEM camshafts and lifters are known for their exceptional durability. Upgrading to aftermarket cams can help ensure that the engine components last longer, as they may be made from higher-quality materials or have enhanced design features.

1. Cost: Upgrading the intake and exhaust cams can be a costly endeavor, as it requires not only the purchase of the camshafts but also the necessary lifters, gaskets, and other related hardware.

2. Installation Complexity: The installation process for these upgrades can be quite involved, requiring extensive engine disassembly and reassembly. This complexity increases the risk of installation errors and potential damage to the engine if not done correctly.

3. Potential for Increased Emissions: Depending on the specific cam profile chosen, upgrading the cams may lead to increased emissions. This is due to the engine burning more fuel to produce the increased power output.

Considering the pros and cons, upgrading the intake and exhaust cams on a BMW E34 M50, E36 M52, 328i, or 528i can lead to significant performance improvements. However, these upgrades come with a considerable investment in both time and money. It is essential to carefully consider the advantages and disadvantages before deciding whether or not this modification is right for you.

If you are truly committed to upgrading your BMW's performance, it is recommended that you consult with a reputable BMW specialist or performance shop. They can help assess your specific engine and driving needs, and recommend the most appropriate intake and exhaust cams for your vehicle. Additionally, they can offer professional installation services and valuable advice on potential modifications that may complement your cam upgrade.
