The K&N 57-2540 FIPK air intake system replaces the restrictive factory air filter and air intake. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your 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 57-2540 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 mass air sensor and air temperature sensor. 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, a ratchet set and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

K&N 98-01 Ford Ranger / Mazda B2500 L4-2.5L Performance Intake Kit - 57-2540 FAQ
It is listed for: 1998-2001 Ford Ranger; 2001 Ford Ranger; 1998 Ford Ranger and more (see the full list above). Pick your vehicle on this page to check your exact year and trim.
Yes. It carries CARB Executive Order D-269-26, which makes it legal to install on street vehicles in California. Keep the EO number with your records for a smog check.
The maker's installation guide is on this page — see Installation guide under the part details for the step-by-step and the torque figures. Work on level ground with the car properly supported, and torque every fastener to the maker's figure. If the job is beyond your tools, any shop that does this kind of work can fit it.
Most intakes work with the stock tune. When an intake changes the sensor housing size, the maker says a tune is required.
Follow the maker's service interval. Dry filters are blown out or washed; oiled filters are washed and re-oiled with the maker's kit. Over-oiling can foul the airflow sensor.
Yes. Most intakes make the induction sound louder, especially at wide throttle.
Yes. An intake is usually a bolt-on job with hand tools; the maker's guide covers the clamps and the sensor move.
A full intake kit includes its filter; a replacement filter is sold on its own. See What's in the box above.
Yes — monthly options show right under the Add to Cart button. Affirm, Klarna, PayPal Pay Later and Snap Finance are offered at checkout, and checking what you qualify for does not affect your credit score.
Install and care: cold air intake
Before you start
- Read the maker's guide for where the airflow sensor moves to.
- Have the clamps and hand tools the guide names within reach.
Do
- Seat every coupler fully and tighten the clamps evenly.
- Service the filter on the maker's interval and use the maker's cleaning kit.
Don't
- Don't over-oil an oiled filter; it fouls the airflow sensor.
- Don't run the engine with a coupler loose.
