2005 2006 Toyota Tundra Sequoia Owners Gain 9.54 HP with KN Air Intake
K&N 57-9027 air intake system with air box cut out to see filter
K&N has developed an air intake system (57-9027) for the 2005 and 2006 Toyota Tundra Toyota Sequoia 4.7 liter V8 engine. K&N dynamometer tests show a 9.54 horsepower gain at 5472 RPM for this air intake kit.
Take a look at our 57-9027 features video to see dyno testing in progress.
K&N air intake systems are designed to smooth and straighten the airflow going into your engine while also reducing intake restriction and providing excellent filtration. The result is power that you can feel.
The K&N unique air filter (E-3034) is designed to incorporate the factory air box and carbon trap. This air intake system is street legal in all fifty states.
K&N air intakes are designed work with factory computer settings. Simply remove the factory air box assembly and replace it with the 57-9027. The mass air sensor adaptor is precision CNC machined for accurate mass air flow readings.
Installing a K&N performance air intake system can make your vehicle run better. Drivers can rely on extra horsepower when pulling a trailer, passing on a two lane road, or simply letting loose on the open road.

Hi, Automotive Engineer here.
I'm sorry, but cold air intake systems are more or less a joke. If you'd like to understand why, install air temperature probes inside your engine, Yeah, yeah, you'll have to drill some holes, but here's what you'd find:
Yes, you are getting cooler air in the INTAKE TUBE. However, as soon as you enter the throttle body, you are faced with lots of thermally conductive metal which is at operating temperature – As the air travels through the throttle body, intake runners, and eventually into the cylinder head, it heats up. The temperature difference between air entering from a true “cold air intake” and your factory designed airbox is negligible. A *real* dyno test will show this – I'm not talking about the doctored dyno tests that cold air intake manufacturers show you; I'm talking about an objective test which plots your torque curve vs RPM, with the same conditions each time.
IMO, the small difference is not worth it. If you take the integral of the curve on some engine condigiurations, you will find that you have hardly gained anything, and have simply “moved” power from a lower RPM to a higher one, or vice versa.
Cold air intakes are for kids who like bling bling under their hoods. Nothing beats a properly tuned (professionally modified or stock) engine management system. These claims of huge power/economy increases with cold air intakes are 100% bunk!!!
Hi guys what type of horsepower gain would I see from just a stock SCT 93 octane tune with my stock airbox?? Im debating ordering a K&N kit but…
