Supertech Mazda Miata 1.6L Dual Valve Spring Kit (70lbs at 34.2mm Installed Height)

If you're working on the engine of your Mazda Miata with the 1.6L engine, this Supertech Dual Valve Spring Kit is designed to handle more aggressive camshaft profiles and higher RPMs. This kit replaces your stock valve springs with a well-built dual spring setup, which helps ensure the valves close reliably even under demanding conditions. This is crucial for maintaining engine performance and preventing valve float, especially when you're pushing the engine harder.

This kit features dual springs, meaning there are two springs working together for each valve. This design offers increased spring pressure and better stability compared to single springs. Specifically, these springs provide 70 pounds of pressure at an installed height of 34.2mm. This level of pressure is often necessary when upgrading to performance camshafts that have more lift and duration, as they require stronger springs to keep up and prevent bouncing. The dual spring configuration also helps to dampen harmonics, leading to a more stable valvetrain operation.

When rebuilding or modifying your Miata's 1.6L engine, choosing the right valve springs is a key step in achieving your performance goals. This Supertech kit is a popular choice for enthusiasts looking to build a more robust and responsive engine. It's important to ensure you have the correct tools for valve spring installation, as this job requires compressing the springs to seat them properly. Always refer to your vehicle's service manual or the manufacturer's installation guide for specific procedures and torque specifications.
