Scope of delivery: - 1x upgrade turbo manifold cast steel 1.8T K04Technical data: - Cast steel (high temperature resistant) - K04 flange - Pipe diameter approx. 34.5mm - High FlowFits directly on original turbo. Longer bolts are required.Description: Our cast steel manifolds are manufactured in a metal mold from high-quality cast and then CNC-machined. Minimal adjustments may be necessary because the diameter of the manifold is larger. In contrast to the tubular manifold, this one is more durable. The cast steel manifold can withstand very high exhaust temperatures. It fits on the original turbo or on the K04-023 upgrade charger. Only longer bolts are used.INFO: as the holes in the turbo flange pattern are not always 100% accurate, the downpipe may no longer fit correctly. This results in adjustment work. Due to the stainless steel casting, the screws can come loose from the turbocharger.suitable for: - Audi S3 210/225hp - Audi TT 225hp - Turbocharger K04-020, K04-22, K04-023Optional: - matching screws
