The IE Performance Valve Spring & Titanium Retainer kit features optimized spring rates explicitly designed for your Audi 4.0TT EA824 engine (C7/C7.5 S6, S7, RS7, & D4 S8). Engineered with exacting specifications to provide proper valve control preventing valve float in high-power and high-revving applications.
REV HIGH WITH CONFIDENCE
Increasing your engine's power output often comes with modifications that require more RPMs to get the most out of it, such as larger turbochargers and race builds. Upgrading those components without changing the valve springs can leave you with a short power band or cause valve float and other significant damage.
ONLY TRUST YOUR ENGINE TO THE BEST
Unlike other inexpensive valve spring kits that adopt a one-size-fits-all approach, we take a completely different strategy. Our kits are not haphazardly selected stiffer springs that might fit but rather meticulously designed by experts who understand the unique valvetrain in the Audi C7 4.0TT engines. We recognize that using the wrong stiffness or poorly constructed springs can be disastrous, leading to potential engine failure and undoing all your hard work and investments. With our kits, you can be confident that you have the perfect match for your engine's needs, ensuring optimum performance and durability.
THE ULTIMATE SPRING & RETAINER KIT
Crafted from the finest spring wire in the world, our IE valve springs boast unmatched durability thanks to a patented multi-stage shot peening process that significantly minimizes failure rates. The precision-engineered titanium retainers feature an impeccable surface finish and stringent tolerance control, guaranteeing an extended lifespan. At our in-house test facility, each application undergoes rigorous testing to ensure optimal performance on your engines. Count on our spring and retainer kits, meticulously matched and extensively tested, to elevate your engine's capabilities, delivering maximum performance and unwavering reliability.
