ISP 1.8T 20V Turbo Race Valve Spring Kit including Titanium Retainers

The ISP 1.8T 20V Turbo Race Valve Spring Kit with premium titanium retainers is the perfect upgrade for anyone looking to run their engine at higher boost pressures. Stock valve springs reach their limits under increased boost and can cause unintended intake valve opening. This results in power loss, misfires, and unreliable engine performance, severely limiting engine potential.

Our valve springs are specifically engineered for racing and high-performance applications. They guarantee fast and precise valve opening and closing, prevent valve float, and ensure reliable operation even at extreme engine speeds over 7500 RPM.

The use of lightweight yet extremely durable titanium retainers reduces the reciprocating mass in the valvetrain, allowing for higher RPM stability and improved throttle response. The materials used are high-strength and tempered to withstand maximum thermal and mechanical stress.

The kit is complete and plug & play installable — compatible with hydraulic and solid valve train systems, specifically designed for all VW and Audi 1.8T 20V turbo and naturally aspirated engines.

Technical Data:

• Maximum force intake valve: 56 kg at 24.00 mm lift
• Maximum force exhaust valve: 84 kg at 22.5 mm lift
• Maximum valve lift: up to 13 mm
• Valve springs material: High-strength tempered steel
• Titanium retainers material: High-strength, lightweight titanium alloy
