The 57 Series Generation II air intake, also referred to as an FIPK®, is K&N's ultimate performance product. These performance intakes are designed to increase power by as much as 10%. 57 Series FIPK's are CARB exempt, street legal in all 50 US states, come with K&N's Million Mile Limited Warranty and are guaranteed to increase power. K&N air intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This translates into more power and torque for your vehicle. The air filters on these kits are washable and reusable. Most of our air intake systems are easy to install using tools commonly available (see installation instructions). [MORE]

 The only negative is that it makes an already loud truck a bit louder. The instructions are quite good, but the photography is average at best. I am glad I didn't throw anything away from the old intake housing, because quite a bit of it was reinstalled. Truth be told, you saved my life, because no factory intake housings were available for love nor money.  Yes, I destroyed the previous one with starting fluid. My old F-250 Power Stroke should make it to 300,000 miles soon. Thanks.
