A bigger catch can means less frequent drainage. The race-inspired baffled system, combined with a built-in surge tank design, allows for spirited driving without the can filling up too quickly. Is the CTS catch can worthwhile? Absolutely. For normal daily driving and relatively stock to Stage 1 cars, I can honestly recommend it. In my case, I’m constantly working on improving my Audi TT Quattro in order to surpass tuned TTS power, which is why I post pictures and videos of my upgrades as they happen. Best.

 turbo.  Months of pampering had finally come to their climax—the break-in period had been reached, and the TT was finally ready for its tune-up. However, this was not going to be your usual filter-and-plugs ordeal, not in the slightest. I had spent weeks, if not months, researching the known weak points of the EA888.2 engine and made it my mission to ensure they were addressed. The first was the consistently problematic positive crankcase ventilation (PCV) plate integrated into the aluminum valve cover. This emissions system is designed to route gases that enter the crankcase back into the intake stream to be reburned in the combustion chamber. However, it is prone to failure, often without warning, allowing oil to enter...

Here’s your edited version with improved grammar, clarity, flow, and consistency while preserving your technical tone and structure: Why would you need an oil catch can system on a modern direct-injection engine? When OEM crankcase ventilation systems fail, they can allow excessive amounts of oil vapor to enter the intake manifold. This not only leads to intake valve contamination and poor sealing, but also contributes to a range of other issues. Another common problem is oil vapor entering the combustion chamber, where it can foul spark plugs and affect piston ring sealing. This is not the type of outcome we want from a performance engine due to a compromised OEM emissions component. To avoid these issues, installing a better-engineered crankcase ventilation solution—such as a dedicated oil catch can—can help maintain, and in so...
