Volvo S40 1.9L F/I 1997-1998, 57i Series Induction Kit by K&N®. This induction kit is an easy and inexpensive way to increase airflow into your engine. It replaces your restrictive factory airbox with a free flowing K&N air filter. Increasing airflow will make more horsepower and torque, resulting in better acceleration. Street legal in most States.
Your OEM air induction system is a compromise between induction noise considerations, underhood space limitations and engine airflow requirements. Replacing that system is an easy way to improve engine performance. Increasing the airflow and air volume into your engine will result in more horsepower and torque and possibly more miles per gallon.
The heart of the 57i Series Induction Kit is the world famous K&N air filter. The kit includes the largest air filter possible for the application, much larger than the size restricted filter that came in the factory airbox. The K&N air filter's increased surface area provides less restriction and more airflow, while capturing and holding more dirt. Depending upon the application, the filter is either directly attached to the throttle body or indirectly attached with a flexible tube.
K&N uses a dynamometer to design its air intake kits to make the most horsepower possible. But their power figures aren't based on just one vehicle, but rather an average of runs by a number of vehicles. This means repeatable numbers and horsepower claims you can count on.
Every 57i Series Induction Kit comes complete with everything necessary for installation, including comprehensive installation instructions. All adapters are manufactured from high quality materials such as steel, aluminum, silicon or reinforced nylon, to ensure long life. The K&N filter can go up to 100,000 miles before cleaning is required. And the K&N air filter is guaranteed for one million miles.

K&N has always been the best in my opinion and with installing this one on my Solstice, my opinion still hasn't changed. I really like the look and style on this particular model as well as the ease of installation. Since installing I have gained around 5 1/4 more horsepower as well as almost 4 more mpg. Doesn't sound like much but you would be suprised at what that little bit would do for your car. You can tell the differece and soon as you hit the gas! Installation was a breeze! It will take you almost twice as long to get the stock air intake off as it will to install this. Such little work and at a decent price it's worth the investment. Over a period of time with the added mpg it will pay for itself.
Bought this product a few weeks back, it was the perfect fit, and my order was delivered in a timely manner. I was evry satisfied with the product and the service. Hands down.
This intake was pretty simple to install and sounds better then I expected. It's got a nice agressive tone on acceleration but once you hit cruiz it's as quiet as a mouse.
