2010 Toyota FJ Cruiser and 4Runner K&N Intake – 12 Horsepower Gain!

At first glance, the 2010 Toyota FJ Cruiser bears a strong resemblance to its famous sibling, the FJ40 Land Cruiser. But underneath its skin, more than 40 years of off-road heritage combine with modern conveniences like satellite radio, a reverse/backup camera, and traction control to bring Toyota off-road enthusiasts a very capable machine. Power is generated by Toyota’s proven and reliable 4.0L V6 engine. However, the true performance potential of the 4.0 is held back, due to restriction in the stock air intake system.

Air intake system designers at K&N knew there was more performance potential hidden underneath the hood of the FJ. The 63-9034 intake system for the 2010 FJ Cruiser, helps uncover much of that hidden performance. The 63-9034 will also fit 2010 Toyota 4Runners with 4.0L V6 engines.

With the K&N 63-9034 restrictive air intake components are removed and replaced with K&N-designed components which have less restriction. The factory air filter and air box are replaced with a reusable K&N conical air filter (part number RF-1044XD), which has very low restriction and excellent filtration. K&N’s air intake tube is constructed of a roto-molded material that provides a smooth inside surface and eliminates even more of the restriction created by the factory intake. Air flow restriction keeps an engine from running at its peak efficiency and power output. How much power does restriction rob from a 2010 FJ? K&N testing shows about 12 horsepower and 13.91 lb.-ft. torque at 4600 RPM!

A powder-coated steel heat shield protects the air filter from engine heat, as well as the occasional splashes you might encounter while out on the trail. Detailed, photo-illustrated instructions make the 63-9034 easy to install, requiring only basic hand tools. You can even watch an installation video of this air intake on a 2010 FJ Cruiser. Installation of the K&N 63-9034 can be completed in 90 minutes or less, and is backed by K&N’s Million Mile Limited Warranty.

    is there a increase in gas mileage that can be expected for normal driving conditions? As I drive around town and even on the highway I seldom reach 4600 RPMs. I would love to have an increase in MPGs on the highway, just not sure if this would help there.
