The K&N 57-2578 FIPK air intake system replaces the restrictive factory air filter and air intake tubing while retaining the factory air box on specific Ford Mustang GT models. K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow for a guaranteed horsepower gain. This allows your engine to inhale a larger amount of air than the factory air filter and air intake assembly. More air means more usable power and acceleration throughout the engine's RPM range. The 57-2578 air intake comes with a replacement K&N high-flow air filter and an aerodynamically engineered intake tube that easily connects to your vehicle's factory air box and throttle body. The air filter can be used for up to 50,000 miles before servicing is needed depending on driving conditions. This air intake system is designed for quick and easy installation with commonly available tools. This air intake meets California emission standards and is legal for use in all 50 states.

Features:

  • Guaranteed to increase horsepower and improve acceleration
  • Custom designed and engineered for each application
  • Works with OEM computer system
  • Includes the world's best air filter, the K&N filter
  • Easy to install
  • Up to 100,000 miles between servicing
  • Million Mile limited warranty

The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine’s RPM range. The air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive chrome-like finish that's made to last and it accommodates the factory mass air sensor and a couple of replacement silicone crank case vent hoses. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less. Some K&N 77 series air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the vehicle applications and specific CARB status for each vehicle and air intake.

Great chair
You sit on it more than in it. It's a bit firmer than my old one, but hopefully it will soften up as the years pass. Otherwise, great chair, easy to put together. The theater lights are a very cool touch at night.

Paid for Protection, Got Rejection — Asurion Makes Claims Unnecessarily Difficult
I purchased the 2-year Asurion protection plan along with my Mcombo recliner, expecting peace of mind in case something went wrong. Unfortunately, when I actually needed to use the plan, the experience was frustrating and disappointing from start to finish. I submitted a claim and uploaded every document available to me—order confirmation, invoice details, and proof of the protection plan purchased through Amazon. Despite this, I received a generic rejection email stating that “documents are missing,” without any explanation of what exactly was lacking. Trying to resolve the issue was even more frustrating. Finding a working customer service number was unnecessarily difficult. When I finally managed to speak with a representative, the interaction was unhelpful and dismissive. The agent requested a document that does not exist in my purchase records and offered no guidance on how to obtain it. There was no attempt to clarify, assist, or move the process forward—only a rigid insistence on requirements that were not properly explained. At no point did I feel that Asurion was trying to help resolve the claim. Instead, the process felt designed to discourage follow-through. A protection plan should simplify problems, not create new ones. Based on this experience, the coverage feels like wasted money rather than a safety net. I would strongly recommend reconsidering before purchasing an Asurion protection plan.
