K&N 57i Series Induction Kits are specifically designed for each
different vehicle and will free your car from the size restriction that comes
with the factory air box. Each kit is designed to provide more power throughout
the RPM range by increasing the amount of air your engine uses. As well as
increasing power you may also see gains in fuel economy. The extra surface area
of these open-air air filters provide even more airflow at lower restriction
than a K&N O/E replacement filter which is always limited to the size of the
factory air box. The larger air filter also captures and holds more dirt
increasing its service life before a cleaning is required (up to 100,000 miles).
The filter is either directly attached to the engine carburetor or throttle body
or indirectly through a tube assembly running from the filter to the engine. All
adaptors are made from high quality materials such as steel, aluminum, silicon
or reinforced nylon to ensure long life.
Benefits
- More power; by getting an increased airflow to your engine it's
allowed to "breath" easier giving it more horsepower.
- Increased MPG; a rise in the miles per gallon of your car is also a
benefit of an intake. Typically 1-2 miles per gallon is added simply with
the addition of this intake.
- More aggressive; adding an aftermarket intake makes your engine
bay more appealing and more aggressive.
- Distinct sound; when you have a stock intake it isn't audible,
but the K&N 57i Series maximizes the airflow to your engine which
allows you to hear your intake working.
- Saves money; the intake will last your car a lifetime so no more
wasted money on paper filters.
- Hassle free; with standard OEM paper filters they need changing
roughly every 12,000 miles, but with the
K&N 57i can go without servicing for up to 100,000 miles.
About Intakes
Adding an aftermarket intake is one of the easiest
and most cost effective ways to increase your cars power and get better fuel
economy. Intakes take the place of your restrictive factory intake
and intake housing, allowing your engine to "breathe" easier and get the air it
needs. This translates into a better throttle response, more horsepower, and
better gas mileage. The filters they come
with are washable and reusable, meaning you wont need to buy a new paper air
filter every time it needs to be replaced. In the long run this saves you time
and money associated with using paper
filters.
