Supertech Mazda Miata 1.8 1.8L Dual Valve Spring Kit

This kit includes a full set of Supertech dual valve springs and matching retainers for your Mazda Miata 1.8L engine. These springs are designed to handle the increased demands of modified engines, especially those seeing higher RPMs or more aggressive camshaft profiles. When you're pushing your engine harder, especially during track days or spirited driving, the stock valve springs can sometimes struggle to keep up, leading to valve float. This kit addresses that by providing a stronger, more stable valve spring setup.

Supertech is known for making well-built engine components, and these springs are no exception. They are made from high-strength spring steel, chosen for its ability to withstand the constant stress and heat cycles inside an engine. The dual spring design offers a more stable valve motion compared to single springs, which is crucial for preventing valve float at high engine speeds. This improved valve control means your engine can rev more freely and safely to higher RPMs, allowing you to extract more performance. They are designed to fit right into your Miata's cylinder head, making the installation process straightforward for someone familiar with engine work.

If you're rebuilding your engine or upgrading your camshafts, a dual valve spring kit like this is a really important piece of the puzzle. It ensures that your valvetrain stays synchronized with the engine's rotation, preventing costly damage from valve float. Make sure to consult your engine's service manual for the correct installation procedure and any specific tools you might need.
