Mazworx S14/S15 VTC Plug

The Mazworx S14/S15 VTC Plug is designed for Nissan SR20 engine enthusiasts upgrading S14 and S15 chassis vehicles. In high horsepower builds, the factory variable timing cam (VTC) intake gear is often deleted to prevent failure under increased valvetrain stress.

This plug replaces the VTC solenoid once the intake cam gear is removed, ensuring the engine’s variable valve timing system is properly managed. When deleting the VTC intake cam gear, it is important to fit either an S13 intake cam or an adjustable cam gear to correctly set the intake cam timing, as the stock S14/S15 intake cams are typically retarded by 15 to 20 degrees compared to earlier models.

Key Features

• Direct replacement plug for VTC solenoid after intake cam gear deletion
• Compatible with Nissan SR20 engines on S14 and S15 chassis
• Supports high horsepower builds by preventing VTC gear failure
• Available in Billet, Black, and Purple color options

By installing the Mazworx S14/S15 VTC Plug, you ensure reliable engine control system operation while enabling performance modifications that require removal of the VTC intake cam gear. This product is essential for builders seeking durability and proper valve timing adjustments in modified SR20DET engines.
