True Tech Ignition VVT198T Variable Valve Timing Solenoid for GM Vehicles

The True Tech Ignition VVT198T is an intake variable valve timing (VVT) solenoid engineered to restore optimal engine performance and efficiency in GM vehicles. This critical engine management component receives electronic signals from the vehicle's ECU and regulates oil pressure to the camshaft phaser, enabling precise control of valve timing and lift duration at different engine speeds.

Key Features:

• Anodized steel componentry resists sticking during sludge buildup for extended service life
• Premium O-rings and gaskets included to prevent premature oil leaks
• Updated internal design addresses original equipment flaws and exceeds OE specifications
• Plugs directly into original electrical harness for easy installation
• Precisely mounts into stock location with all required gaskets included
• Extensively tested in laboratory and vehicle conditions for reliability
• Specifically designed for GM vehicles including Buick, Chevrolet, GMC, Pontiac, Saab, and Saturn models

This VVT solenoid restores smooth engine operation, eliminates rough idle, improves low and high RPM performance, and resolves check engine light codes related to variable valve timing system failures. Professional-grade quality suitable for both technicians and DIY mechanics.
