2004 Scion xB - Power Pages
Pros
Fujita intakes are some of the most complete systems we've installed, and our xB unit is no different. The filter sits away from the engine bay, behind the headlight for a clean, cool charge of air. The tubing channeling the charge to the intake meets the throttle body perfectly, allows for factory battery placement and accommodates the stock maFs with minimal restriction. the intake's attached bracket stabilizes the unit, and an additional bracket is included for a stock clip that normally rests on the factory airbox. most importantly, the unit brought solid low and mid range horsepower and torque gains and a much throatier sound under full throttle.
Cons
Installation of the intake caused a sizeable dive in power from 6,100rpm until fuel cut off. This is definitely a drawback to modifying the xB, but not one that can be attributed to Fujita's intake design; the 1nZ-Fe's Vvti system adjusts cam and ignition timing partially based on readings from the maFs. In short: switching from a restrictive intake and flat filter to a free-flowing, cone filter-andtube unit causes the maFs to read air mass in different amounts relative to engine speed, which seems to throw off the VVti system, causing timing adjustments that aren't optimized for the new conditions; or something a good tune could straighten out.

Notes
Removing the factory battery and plastic engine cover is a must during installation. when removing the maFs, be sure to replace its factory round rubber gasket before re-mounting into the Fujita unit. A wiring plug normally rests on the factory airbox-relocate it via the included metal bracket and fastener. Also, make sure to replace the factory rubber hose connecting the valve cover with the intake with the included silicone one.
