       Printer Image
The engine in the Mazda B4000 series is the same as the one used in the Ford Ranger 4.0l V6 for 2004, 2005, 2006, 2007, 2008, 2009, 2010 and 2011 models. This allowed K&N to design one intake to fit both models.  With the addition of K&N's new 77-Series High-Flow Performance Kit (77-2561KP) Ford Ranger 4.0L V6 and Mazda B4000 4.0l V6 owners can realize an 11+ horsepower gain while driving.

The 77-Series Intakes' show-quality appearance has under-the-hood style with a polished aluminum finish perfect for the Ford Ranger and Mazda B4000.

K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your truck's engine to utilize a larger volume of air than the OEM air filter assembly. More air means more power and torque when you need it.

77-Series Intakes are designed to be installed with simple hand tools in under 90 minutes, is street legal in most states and includes the famous K&N Million Mile Warranty.
