APR Valve Spring System For VW/Audi/Porsche - 1 Set

Valve float on tuned 2.0T engines is a known problem, and when a valve doesn't close fast enough, the piston finds it. APR's Valve Spring System was designed specifically to fix this without creating new problems. The springs are 20% stiffer than the EA113 K04 (MK6 R) setup, but the retainers are 71% lighter, so the combination doesn't overpower the OEM valves or erode the aluminum spring seats. That balance is what makes this work where cheaper kits fail. If you're running aggressive cams, a bigger turbo, or high-RPM software, these belong in the engine.

Features:

• 71% retainer weight reduction vs. EA113 K04
• 20% stiffness increase
• Eliminates valve float
• ASTM A877A OTSC round wire steel springs
• 6AL4V American titanium retainers
