Product Details
Give your B6 A4 1.8 T the clutch it deserves. Why settle for a stock clutch replacement when our Stage 1 Clutch Conversion kit gives you so much more? For your next clutch replacement, move up to the new ECS Tuning lightweight flywheel with an S4 clutch disc and pressure plate.
Get more.
Smooth Operation: This is a package you can live with in your daily driver. Clutch hub damping springs absorb driveline power pulses and vibration to keep things smooth at idle.
Improved Responsiveness: The ECS RA4 lightweight flywheel weighs in at a trim 12 pounds, compared to the hefty 26 pound flywheel shipped from the factory. Now your engine won't have to waste power lugging all that mass up to speed. Off the line? That's like hauling 250 fewer pounds of vehicle weight.
Improved Power Transfer: Send more power to the wheels with a larger diameter S4 clutch and pressure plate combination, an increase in diameter from 228 to 240mm. With clamping strong enough to handle the B5 S4's 251 horsepower, this clutch will get the job done.
Direct Fit: Bolt these beauties on to your 1.8T with no additional modifications. The kit includes original equipment hardware and clutch alignment tool, so things slide together easily.
