HG Motorsport Catch Can Kit VAG 2.0 TSI EA888 Gen4 VW Golf 8 GTI / VW Golf 8 CS / VW Golf 8 R / CUPRA Leon KL / SKODA Octavia NX

The TSI Catch Can Kit prevents oil vapors from entering the intake manifold, avoiding carbon buildup on the valves and ensuring cleaner, smoother, and more efficient engine operation. This is especially important in direct-injection TSI engines, where the lack of fuel washing leads to deposit formation. The system also solves common crankcase ventilation issues that can cause smoke, misfires, power loss, and even severe engine damage.

Advantages:

• Oil vapors are routed to the catch tank

• No carbon buildup on intake flaps and intake valves

• No excessive oil consumption

• No power loss

• Cleaner combustion

• Compatible with the original engine cover

• Suitable for AWD and FWD models

• No need to modify the washer fluid reservoir

• Pre-cut hoses with pre-assembled fittings

• OEM gasket can be reused

Disadvantages without a catch tank:

• Carbon buildup → valve breakage → possible engine damage

• Power loss → rough idle

Technical details:

• Chambered catch tank with sintered filter

• Volume: approx. 1200 ml

• Black braided stainless-steel hoses with racing fittings

• CNC-machined PCV fix

• Black anodized

• Plug & Play kit

• Complies with Euro emissions standards

• Can be emptied from below without removing the tank

• No certification

What sets this system apart from simpler solutions is that it modifies the entire PCV block, preventing engine oil from “sloshing” into the return line — a common issue on EA888 Gen3/4 engines, especially under sporty driving conditions.
