Mazdaspeed VVT Replacement Parts Kit

While the DISI-MZR engine found on the Mazdaspeed 3, 6, & CX-7 is a fun and potent powerplant, it does have some common issues that must be addressed with age and if you want to produce more power. One common issue is the OEM VVT Actuator which controls the Variable Valve Timing of the intake camshaft. Actuator failure commonly sounds like a rattle and/or chain slap from the passenger side of the engine. This is due to the actuator losing its ability to hold oil pressure and keep tension on the timing chain.

Luckily, Mazda revised the OEM VVT Actuator with a stronger and more durable design that eliminates this failure from happening in the future. On average, we see engines needing this part replaced once they are in the 70k to 100k mile range.

We have put together a complete VVT Actuator Replacement Kit so you don’t have to worry about which parts are needed and which are not!
