Fitment for the Mazda Miata

Listed for the Mazda Miata with the 1.8L engine. Check your year, model and trim against the title before you order.

What it does

Valve springs close the valves and keep them following the cam at high rpm. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.

Installation & tips

• Check installed height and coil bind against the spec from the brand before you start the engine.
• Retainers and locks: Make sure they match the springs.
• Valve stem seals: Replace them while the springs are off.
• Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
