The K&N 57-2542 Air Intake fits some Ford Bronco, Ford F150, and Ford F250 models. See vehicle applications link for details.
The K&N 57-2542 FIPK air intake system replaces 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 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 57-2542 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 dual port throttle body for a guaranteed power gain. The tube accommodates the factory crank case vent hose. The oversized tapered 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 and requires commonly available tools. 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 57-2542 Air Intake Product Reviews

Tuesday, April 24, 2018 - Part 57-2542
It looks great under the hood. The bracket to brace it and hold it in place could be better. Air filter is rubbing on a bolt and has damaged air filter. I recently deleted the ac compressor and now the bracket is too short ill have to make one. Good product however install kit could be redisigned regarding the metal brackets and braceing to center it and hold it up so it doesnt rub.

This K&N product was bought for a 1991 Ford Bronco complete restore project, with 5.0 liter engine. It makes a nice difference in sound and performance. It is extremely easy to install. Definitely a good buy.
