Takeda Attack Cold Air Intake System Attack is the Takeda Cold Air lineup. These intakes put the filter behind the front bumper, where the intake can ingest cold, dense air. All Attack version intakes come complete with Takeda's Synthetics Pre-Filter. The research and development team test and develop intake systems that will produce the most horsepower and torque output possible. The in house engineering team performs numerous tests until they are satisfied with the results. The performance air filters are made in house in the USA. Quality, craftsmanship, performance, appearance, sound...nothing is compromised, everything is optimized. Takeda is overseen by Advanced Flow Engineering (aFe). aFe heavily emphasizes the engineering behind their products. Designing, researching, engineering, prototyping, testing, and production of all parts of the intake systems are done in house. Everything being done in house leads to higher quality control. Higher quality control leads to higher quality products.
