5-Inch Cold Air Intake System

The Integrated Engineering IEINCI4 is a high-performance cold air intake system engineered for select Volkswagen and Audi vehicles equipped with the 1.4T engine. Key features include a massive 5-inch diameter air filter for increased surface area and superior airflow, a turbo inlet pipe to optimize air delivery, and an integrated heat shield that works to isolate the filter from engine bay heat. Designed for direct bolt-on installation, the IEINCI4 aims to enhance engine responsiveness and power output. The high-flow filter is constructed with quality materials to ensure efficient filtration and durability. This intake system is a direct replacement for the stock airbox and plumbing, often leading to noticeable improvements in throttle response and an audible induction sound. This cold air intake is compatible with various VW Jetta MK6 models with the 1.4T engine, as well as certain Audi B9 A4 and A5 models with the same engine. Fitment is specified for years typically ranging from 2011 through 2014 for some applications, and later years for others, so verifying specific vehicle compatibility is recommended.
