K&N Engineering has released a new 69-Series Typhoon Air Intake (69-4515TS) for the 2005, 2006, 2007, 2008, 2009 and 2010 Chevrolet (Chevy) Cobalt 2.2 liter L4. K&N dynamometer test show a 6.6 horsepower gain @ 4750 RPM for this powder coated silver intake. "The power gain is exceptional for this engine," said K&N Project Technician Nestor Cabrera. "We used a slightly larger than average filter (RU-5147) for this car to ensure that the engine would get all the air that it needs."

This 69-Series Typhoon Air Intake (69-4515TS) uses the factory mass air flow sensor installed in the tube and a special radiused filter adapter with heat shield. "The radiused adapter helps provide smooth non-turbulent air flow into the intake tube," said Cabrera. "The heat shield isolates the filter from the engine compartment keeping the air around it cooler."

The design of this vehicle played a major role in the development of this 69-Series Kit. The throttle body placement required the development of a special 90 degree silicone hose with a very tight radius. "We designed this K&N Kit (69-4515TS) so the intake tube would follow the cars natural lines," said Cabrera. "It places the air filter in the location of the stock air box."

With all K&N 69-Series Typhoon Air Intakes there is a thorough development procedure which requires the use of multiple test vehicles. "We conducted a little more testing than usual on this particular Air Intake before reaching this design," Cabrera said. "We were however, able to locate vehicles easily for this project."
