2005-2010 Jeep Grand Cherokee WK Throttle Body Spacers

Throttle body spacers have been a debated upgrade for years, but the WK community has kept them in the conversation for a reason. Properly matched 2005-2010 Jeep Grand Cherokee WK Throttle Body Spacers create additional air turbulence entering the intake manifold, which improves fuel atomization in a way that tends to show up in throttle response and low-end torque before anything else.

 

The 3.7L and 4.7L in the WK respond differently to throttle body modifications, and buyers expecting dramatic dyno numbers are going to be disappointed. The gains are real but subtle and most noticeable at part throttle, which happens to be where most daily driving happens.

 

Throttle body spacers are one piece of a broader intake and engine performance picture for the WK. Cold air intake options that pair well here are at 2005-2010 Jeep Grand Cherokee WK Cold Air Intakes & Air Filters, and the full engine performance catalog for this generation is at 2005-2010 Jeep Grand Cherokee WK Engine Performance Parts.
