K&N has also released a new 69-Series Typhoon Air Intake (69-8701TP) for the 2006 to 2011 Lexus IS350 3.5L and the 2005, 2006, 2007, 2008, 2009, 2010, 2011 and 2012 IS250 2.5L. K&N dynamometer tests show an estimated 11.2 horsepower gain @5800 RPM. "The power gain is exceptional for an engine this size," said K&N Project Technician Nestor Cabrera. "With all our kits there is a thorough development procedure which requires the use of multiple vehicles to ensure a consistent horsepower and torque gain on every car, thus there is a lot of testing that the kit goes through before it is finalized production."

K&N used multiple vehicles to ensure a consistent horsepower and torque gain on every car and was able to locate the cars through the K&N Filters website car database.

The 69-Series Typhoon Air Intake (69-8701TP) uses the factory mass air flow (MAF) Sensor installed in the tube and a high flow air filter with a heat shield. "The high flow air filter helps provide smooth non turbulent air flow into the intake tube by incorporating a radioused mounting flange," said Cabrera. "The heat shield isolates the filter from the engine compartment keeping the air around it cooler."

The design of the Lexus played a major role in the development of the polished aluminum 69-Series Typhoon Air Intake (69-8701TP). "Special care was taken to ensure that the intake system followed the vehicles lines and that it did not obstruct or rub against other parts in the engine compartment," said Cabrera. "We designed the intake system so that all the factory accessory and engine covers could be reused."

The K&N Air Filter we used in this air intake was the RU-4990 , said Cabrera. "We considered air flow requirements, location and space," he said. "The flange helps provide smooth air flow into the intake tube."
