Review on ๐Ÿ”ง Spectre Performance 11259 Throttle Body Spacer for Ford F150 Truck, Expedition, 5.4L (2004-2009) by Harald Patterson

Revainrating 3 out of 5

Ideal for spare parts

I say it fits but it does everything well. If the box claims to increase performance, that's wrong. The diameter of the TB spacer is less than twice the diameter of the intake manifold and throttle body. As a result, less air gets into the intake tract, which reduces performance and increases fuel consumption. I've found that when merging with traffic I need to step on the gas after installation. So I compared two holes and figured it out. This can be fixed by drilling the hole to the same diameter, but Y? I installed the factory TV.
