The K&N 57-3515 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Honda Ridgeline models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Ridgeline’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-3515 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 an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory crank case vent hose. 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 using the existing factory mounting points. The tools needed a screwdriver, socket set and pliers. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

 So far, so good. My son & I own a 2008 Honda Ridgeline RTS. If I resist stomping on the gas pedal, do strictly highway driving, drive the speed limit, and dependent on how strong the ethanol is in the gas, I can average 20 miles to the gallon. My son & husband installed this air filter into both of our vehicles. My son does mostly city type of driving, and I do a mixture of driving. So far I have gained a bit of an increase in the mpg driven over what I had during these winter months. I have definitely gained an increase in the amount of miles driven per tank.
