K&N Cold Air Intakes add heat shields and use a tube that extends beyond the engine bay away from the heat of the engine to maximize cool air. This is a key ingredient for horsepower.

Included in this Typhoon Air Intake System, like all other K&N Air Intake Systems is a high-flow air filter (RU-4990) designed to provide increased surface area. The heat shield isolates the K&N Air Filter from the engine compartment and allows the K&N Air Filter to receive a consistent flow of fresh cool air.

It takes less than 90 minutes to install this air intake with simple hand tools. K&N Typhoon Air Intake Systems are designed to improve engine performance along with under the hood visual appeal.

Air Filter for 2005 and 2006 Scion tC Air Intake 69-8608TFK

K&N Engineering released a new Air Intake (69-8608TFK) in flat black for the 2005 and 2006 Scion tC 2.4 liter engine. K&N selected a few vehicles from Toyota that had hydrocarbon trap filters in the airboxes and worked with CARB's criteria to design emissions friendly air intakes. "This Typhoon Air Intake System is equipped with a hydrocarbon filter in the air box," said K&N Project Technician Nestor Cabrera. "Our Typhoon Air Intake System uses the factory upper air box with the mass air flow sensor. This allows the consumer to retain the CARB mandated emission device. Other additions include a special high flow K&N Air Filter (E-3038) and heat shield."

The high flow K&N Air Filter is mated to the factory upper air box by an exclusive K&N designed cage. The air intake heat shield isolates the air filter from the engine compartment and helps to funnel cooler outside air into the air filter. The CARB mandated hydrocarbon filter isolates evaporative emissions within the intake track. The E-3038 air filter is one of the first of its kind from K&N. It has a unique trapezoidal shape that was made specifically for this application.

K&N previously released air intakes for the 2005 & 2006 models with the traditional cold-air design. Performance of the 69-8608TFK is improved slightly over the K&N original air intake systems, 69-8607TB and 69-8607TS."

K&N dynamometer test show a 7.58 horsepower gain @ 5022 RPM for this intake system (69-8608TFK). "The horsepower and torque gains are exceptional for an engine of this size," said Cabrera. "The vehicle design played a major roll in the development of this Typhoon Air Intake. We took special care to ensure that the K&N Intake System followed the vehicle lines and did not obstruct or rub against other parts in the engine compartment."

There is a thorough development procedure which requires the use of multiple vehicles at K&N. "This helps give us confidence in our horsepower numbers," said Cabrera. "Our Typhoon Air Intake Systems go through a lot testing before being finalized for production."

It takes less than 90 minutes to install most K&N Air Intakes with common tools. K&N Typhoon Air Intake Systems are designed to improve engine performance along with under the hood visual appeal.

In the A final, Crump was unable to take a podium spot and finished in a disappointing fourth place. “I won my first heat and from there it all went downhill,” said Crump. “I spoke too soon last week thinking that my technical issues from round one had been fixed, but they are still there. We have a lot of work ahead of us to get the problems fixed in time for the next Grand Prix race. I don’t like losing.

Crump is in third place in the World Championship chase. “I have to win races and right now I’m not doing that,” said Crump. “But don’t write me off just yet, there are nine more GP’s to go. People know me as a fighter and not a quitter so I’ll be back.”

Crump uses K&N Engineering products. “The K&N Filters keep the dirt out of the engine,” he said.  "With all the other technical problems we’re having, the one thing we never have to worry about is K&N.”

Round 3 of the 2007 Speedway Grand Prix World Championship takes place in Eskilstuna, Sweden on Saturday May 20th. Eskilstuna is 75 miles west of Stockholm on the Eskilstunaån River.
