We offer a wide range of tuning parts for the Audi A4 B5 Avant 1.6, 1.8T, 1.9 TDI, 2.4, 2.6, 2.8 + Quattro. Most parts are plug and play, i.e., the original part is replaced, and the tuning part is installed without any modifications or with minimal adjustment. This saves a lot of work, money, and time.

Turbochargers

The centerpiece of the 1.8T, aside from the engine, is the turbocharger. We offer various upgrade turbochargers, such as the K04-015 with larger compressor wheel, turbine wheel, and reinforced wastegate plug and play, as weaker wastegates can no longer hold the boost pressure at a certain level and start to flutter, which is why stronger wastegates are needed. As a rule of thumb, from an opening pressure of 0.5 bar, the wastegate can realize a holding pressure of approx. 1.3 bar and then begins to flutter. This allows a maximum of 300hp. The turbocharger hardly differs visually from the original. We have original Borgwarner in our program as well as our own brand "Turbo-parts.de" which we have been selling successfully for over 13 years. These are all finely balanced and have a long lifespan. To ensure the turbocharger also gets enough exhaust gases, a correspondingly large exhaust manifold is needed. Here we also have upgrade manifolds with a larger pipe cross-section that are simply exchanged for the original manifold. For conversions with universal turbochargers e.g. GT28 Turbo or GT30 etc., a manifold with the appropriate flange T25 or T3 is needed, which we also have in our program. If your exhaust housing for your original turbo or upgrade turbo is cracked/damaged you can also purchase it from us.

Having a turbocharger alone is not enough. Naturally, the surrounding parts also need to be exchanged to extract the optimal performance from the engine.

Exhaust Technology

To generate as little back pressure as possible, Downpipes with a larger diameter e.g., 76mm are required so the turbo is relieved and generates less exhaust back pressure. We also offer these with TÜV and with 200 cell or 100 cell sports catalytic converters.

To achieve a sonorous sound and so enough exhaust gases can escape, we have various sport exhaust systems typically from Simons from Sweden with EC approval, meaning they do not need to be registered and can be used legally on the road.

Intake

With upgrade turbochargers or with engines that have been boosted in performance, the original intake hoses tend to collapse, leading to a loss in performance. We offer silicone hoses e.g., intake hoses or boost hoses that can withstand the performance. To achieve more air throughput, sports air filters as well as larger intake manifolds for optimal ventilation are used. Blow-off valves also known as Pop-Off or SUV are essential for the 1.8T, they must also be closed, otherwise, the airflow meter is missing the air diverted into the atmosphere during calculation. For this reason, open valves are not suitable for the 1.8T with the original injection system.

Power Transmission

To transfer the power to the road, sports clutches are essential. We have complete kits with single mass flywheel, pressure plate, friction disc with organic coating, and release bearing that are also street legal, sprung sinter metal discs are also suitable for the street only unsprung types are more recommended for motorsport.

Cooling

To get cool air into the engine a larger intercooler kit or an upgrade intercooler is needed, because cooler air is denser and contains more air Bei uns kaufen Sie A4 B5 Sedan günstig online.
