Review MAZDA Genuine Engine Camshaft Follower fits 2011–2014

The Mazda ZJ38-12-574 engine camshaft follower is an essential component of the Mazda's 1.3-liter, 38mm throttle body injected engine. This camshaft follower, also known as a camshaft lobe following assembly or a tappet, plays a crucial role in the engine's combustion cycle by precisely controlling the timing and duration of the intake and exhaust valves opening and closing.

The camshaft follower is designed as a compact, yet robust part with a durable cast iron construction. It is engineered to fit snugly onto the camshaft lobes and provide a smooth and reliable valvetrain operation. The surface of the camshaft follower features a precise and accurate machining to ensure optimal contact with the camshaft lobes and minimize friction.

This feature provides peace of mind for the vehicle owner, as they can trust that their engine will continue to operate efficiently and effectively, even as the engine wears over time.

Moreover, the Mazda ZJ38-12-574 engine camshaft follower is designed to be a direct replacement for the original equipment part. This means that it offers a perfect fit, ensuring that the engine continues to operate at its optimal performance level. Additionally, it is manufactured to meet or exceed OEM specifications, ensuring durability and reliability.

In summary, the Mazda ZJ38-12-574 engine camshaft follower is a critical engine component that is designed to provide precise control of the engine's intake and exhaust valves. Its cast iron construction, self-adjusting mechanism, and direct replacement status make it an ideal choice for maintaining the performance and reliability of your Mazda engine.

Buying a Mazda ZJ38 camshaft follower involves considering its potential advantages and disadvantages for your vehicle's engine performance and maintenance. Here's a detailed analysis:

1. Improved Engine Performance: A high-performance camshaft follower can lead to increased engine power and torque by allowing for better valvetrain control. This results in more efficient combustion and improved overall engine performance.

2. Enhanced Durability: A high-quality camshaft follower can help extend the life of your engine by reducing wear and tear on the valvetrain components. This can save you money on potential future repairs.

3. Customization: Upgrading to a high-performance camshaft follower allows you to tailor your engine to your specific driving needs and preferences, making your Mazda ZJ38 more responsive and enjoyable to drive.

1. Cost: A high-performance camshaft follower can be a significant investment, especially if you are not experiencing any major engine issues. The cost can vary depending on the brand and quality of the component.

2. Complex Installation: Installing a camshaft follower requires a high level of mechanical expertise and specialized tools. Improper installation can lead to damage to the engine or other components, potentially costing you more money in repairs.

3. Potential Power Imbalance: Upgrading only the camshaft follower without addressing other engine components can result in power imbalance within the engine. This can lead to reduced performance and potential engine damage.

Ultimately, the decision to buy a Mazda ZJ38 camshaft follower depends on your engine's performance needs, budget, and mechanical expertise. If you are experiencing engine issues, upgrading to a high-performance camshaft follower can help improve performance and durability. However, if your engine is running smoothly, the cost and complexity of the installation may outweigh the potential benefits.

If you decide to purchase a Mazda ZJ38 camshaft follower, make sure to source it from a reputable manufacturer, and consider having it installed by a professional mechanic to ensure proper installation and optimal engine performance. Additionally, consider upgrading other engine components to ensure power balance and maximize the potential benefits of the camshaft follower upgrade.
