The 57 series air intake offers all the benefits and design functions of the 67 series while also being 50 State street legal and carb exempt in California. The fuel injection performance kit (FPIK) from K&N Engineering is a dramatic improvement over the previous, the new FPIK generation II air intake system features the largest conical shaped high-flow air filter possible, even using existing mounting holes and points with no fabrication required. The over-sized filter enables a huger increase in airflow over stock replacement filters that are limited to size of the air box.

When possible, the filter is isolated from high engine temperatures by a heat shield designed to lower the temperature of air entering the engine. This cooler air is denser, resulting in more powerful combustion and increased horsepower. Feeding this cleaner, cooler air to your engine is a rotationally molded tube made from interlaced high density polyethylene (HDPE). This unique process results in a precisely shaped tube that reduces turbulence and increases airflow into the engine.

• Dyno-proven results
• Featuring the largest conical high flow filter the engine compartment will allow
• Increased air flow across the entire rpm range
• Uses existing mounting holes and points with no fabrication required
• Engine heat is isolated from intake resulting in cooler, denser air
• Rotationally molded HDPE intake tube to reduce turbulence and increase air flow
• Increased fuel economy means this is an investment that will pay for itself
• 50 State emissions legal
• Will not void vehicle warranty
• Back by K&N limited lifetime warranty

This entire process translates into a complete performance intake kit that is specifically tailored for your vehicle. Couple that with premium clamps, tubes and included adapters for long life and durability and you have the best high-flow intake intake kit on the market.
