K&N Fuel Injection Performance Kit - Lexus IS300 01-05
Our 57 Series Gen II Air
Intake Kits (FIPK's) are built for many different vehicles and
represent a dramatic improvement over a K&N O/E replacement filter
alone; they use only non-metallic rotationally molded tubes that can
reduce air temperature and decrease intake sound over a metal tube.
Restriction can exist BETWEEN an air filter and the engine reducing the
benefit of a K&N Air Filter. The weakest link in the airflow
“chain” robs a vehicle of its natural horsepower. Often that weak
point is the factory air path leading to the Engine. K&N Air
Intake Kits virtually eliminate air path restriction by replacing the
air filter and the entire air path to the engine. The aerodynamically
engineered tube drives a massive amount of air into an engine, which
translates into POWER.
K&N 57 Series kits are
truly state-of-the-art. We start with the largest conical shaped
high-flow air filter we can fit into the engine compartment while using
factory holes and mounting points. This extra filter size provides
even more airflow at lower restriction than a standard K&N O/E
replacement filter that is limited to the size of the factory air box.
The oversized air filter also captures and holds more dirt increasing
the service life before a cleaning is required (up to 100,000 miles).
When possible, the filter is isolated from high engine temperature by a
heat shield designed to lower the temperature of the air entering the
engine, which increases horsepower. Next we attach the filter to a
rotationally molded tube made from interlaced High Density Polyethylene
(HDPE). This process allows us to precisely shape the tube to reduce
turbulence and accelerate airflow into the engine. This is why some of
our tubes have unique shapes that are specifically engineered for each
application. Finally the tube is connected to the engine with adapters
made from high strength materials such as silicon and reinforced nylon
and ensures long life. Put all this together and you have the best
high-flow intake system available today.
