Throttle Body Spacer for Nissan Murano (2003-2006) 3.5L

Billet Aluminum Throttle Body Spacer for 2003-2006 Nissan Murano

What it Does: Installs between the throttle body and intake manifold to increase plenum volume and optimize incoming air velocity for improved off-idle throttle response and low-end torque.

The Stock Murano Intake Bottleneck

The factory intake tract on the VQ35DE-equipped Z50 Murano suffers from abrupt plenum entry transitions and limited manifold volume ahead of the runners. Under immediate throttle tip-in, high-velocity intake pulses encounter sudden boundary-layer shear and directional disruption at the factory throttle body flange. This creates localized turbulence and an uneven air charge distribution across the upper plenum, resulting in sluggish initial pedal response and delayed torque delivery.

The Engineering Solution

Precision CNC-machined from solid billet aluminum with a protective anodized finish, this spacer adds critical volume to the intake plenum while resisting under-hood thermal transfer. Its helical-profile open bore stabilizes incoming velocity gradients, smoothing the transition into the intake manifold runners. The rigid direct-fit construction bolts directly into the factory induction tract with included hardware, maintaining precise vacuum sealing without altering factory ECU sensor calibration.
