The K&N 77-2552KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Ford Ranger and Mazda B2300 models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. 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 77-2552KP 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 replacement silicone 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 existing factory mounting points. The tools needed are a screwdriver and a ratchet set. 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 K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

Once I replaced my stock air filter on my 2002 Ford Ranger to the K&N air filter, I noticed better performance, improved fuel economy, and of course the dependability of the filter. These filters are engineered to outperform anything else on the market I am a K&N customer for life.

I only use a K&N oil filter for my 2002 Ford Ranger. If I had to pay twice as much compared to a regular filter, I would still get it no matter what I am a K&N customer for life Nothing else comes close to these filters I trust the high quality design for dependability and performance.

Purchased the performance intake kit for my 2006 Ford Ranger. Installation was very straight forward and entire process was under an hour. Can tell there has been an improvement in both response as well as improved gas mileage. Will save the cost of the intake kit in under a years time with fuel savings. Great product
