To give the Corolla more power K&N designed a performance air intake system 69-8757TTK in black for the 2009 Toyota Corolla with a 1.8 liter engine. K&N dynamometer tests show the 1.8 liter engine gained 6.37 horsepower at the wheels at 5324 RPMs with this air intake kit.

The 69-8757TTK has lower restriction than the factory air box system. It draws air through a high flow washable and reusable air filter RU-4960 which is protected by a powder coated heat shield. K&N removed the OE air box and intake and built a larger intake system to open up the breathing capacity necessary for the 1.8 liter engine to get the full amount of air it needs for an immediate power gain.

The heat shield directs incoming fresh air from the factory air inlet into the air filter and isolates the K&N air filter from the engine compartment for better performance. The heat shield assembly is installed into the engine bay using factory mounting points and attaches to the intake tube.

All the OE emissions devices are reused and the MAS placed in a location that works with the factory settings. The crank case vent attaches to the mandrel bent intake tube. The 69-8757TTK can be easily installed in 90 minutes or less and is backed by the famous K&N Million Mile Limited Warranty.
