Direct Injection Technology

Gasoline direct-injection technology provides substantial improvements in power and efficiency on internal combustion engines, has become widely adopted in the latest Audi and Volkswagen models. This technology - advertised as FSI, TSI, or TFSI by Audi and Volkswagen - is inherently more efficient than port fuel injection, and allows for increased horsepower and torque throughout the powerband, as well as lower emissions.

Carbon Deposits & Buildup

While the benefits of direct-injection are well documented and worth the added level of hardware and software complexity, there is an inherent downside to completely eliminating port injection. Direct-injected engines from Audi and Volkswagen - particularly early 2.0T FSI , 4.2L FSI, and 5.2L FSI versions - are prone to carbon buildup in the intake ports and on the intake valves, which over time becomes severely detrimental to engine performance and efficiency. These deposits worsen over time, inhibiting airflow, and can even break off and fall into the intake tract, where they can cause damage to the valves and internals.

034Motorsport Carbon Cleaning Services

034Motorsport's expertise in Audi/Volkswagen engines led to the development of a comprehensive Carbon Cleaning Program for Audi/Volkswagen FSI. TSI, and TFSI direct-injected engines. The 034Motorsport Carbon Cleaning Service consists of a trained and highly-skilled technician removing the factory intake manifold, and physically cleaning the carbon deposits from the intake ports and intake valves.

Carbon cleaning is performed port-by-port, with the engine rotated so that the corresponding intake valves are closed. This ensures that no debris fall into the combustion chamber, and all carbon deposits can be carefully collected.

Dyno-Proven Results

The presence of carbon buildup has a severe negative impact on the performance and fuel economy of direct-injected engines, which can usually be noticed by discerning owners as decreased acceleration, intermittent misfires, and increased fuel consumption.

034Motorsport has collected extensive logs and performed back-to-back performance testing on their in-house Mustang AWD dynamometer to validate the effectiveness of Carbon Cleaning Services. In addition, this enables 034Motorsport to provide data for eager customers who are curious to see the quantifiable benefits of Carbon Cleaning Service.

One of the most popular candidates for carbon cleaning is the 4.2L FSI V8 engine found in the B7 Audi RS4, B8 Audi S5, and Audi R8. This engine is prone to carbon buildup, and owners of the high-performance vehicles it is available in will see noticeable improvements with a Carbon Cleaning Service. Below is a before-and-after dyno comparison of a B7 Audi RS4, which gained 42 horsepower 26 foot-pounds of torque from a 034Motorsport Carbon Cleaning!

Carbon Buildup & Carbon Cleaning FAQ

Can I use fuel additives to prevent carbon buildup on my direct-injected engine?

  • You can use fuel additives, but they won't help clean carbon buildup from the intake valves and intake tract. Because fuel is sprayed directly into the combustion chamber on FSI, TSI, and TFSI engines, none of the fuel nor additives will reach the intake ports or valves.

Will installing a catch can kit completely eliminate carbon buildup on my direct-injected engine?

  • Installing a catch can kit may help reduce oil in the intake tract and prevent loss of power due to PCV assembly failures, but they won't completely eliminate carbon buildup in your direct-injected engine. Carbon buildup is typically caused by soot from the combustion process reverberating an depositing on the valve stem and intake ports.

Should I use a different type of oil to prevent carbon buildup on my direct-injected engine?

  • We recommend using Motul 8100 Motor Oil or similar high-quality synthetic oil with the correct specification for your engine. However, switching to a different brand of oil is unlikely to impact carbon deposit buildup.

Can I remove carbon buildup on my direct-injected engine by introducing Seafoam or other chemicals into my intake manifold?

  • No. The only effective way to remove carbon buildup from the intake valves and intake ports is to remove the intake manifold, and physically clean the valves. This is a time-consuming and labor-intensive service that we recommend taking your vehicle to a professional repair facility for.
