CARB Notice
- 50 State Legal - CARB E.O. Number D-670-15
K&N's Fuel Injection Performance Kits (FIPK) are designed to promote performance in stock fuel injected engines by allowing air filtration with least resistance in air flow. In addition to the filter, these Cold Air Intake kits have uniquely designed adapters, creating a radius entry that reduces restriction and allows the engine to breathe a greater volume of air. CARB Certified. The filter recharger kit is sold separately.
Achieve horsepower gains even under varying atmospheric conditions with an FIPK kit, which replaces the entire air intake, isolating the cold air with the use of a custom heat shield and directing the air through a unique chamber delivery system. Dyno test results showed torque increases through the towing ranges of no less than 23 ft. lbs. FIPKs are legal in all 50 states.
To ensure all the power and performance that your fuel-injected engine is capable of providing, install a high-quality K&N Fuel Injection Performance Kit and feel the power! You'll get better acceleration, instant power, and ease in lane changing and passing, even while towing. And remember, K&N delivers performance that's guaranteed for 10 years or one million miles, whichever comes first.
