So I just pulled the throttle body off of my 4.0L and I just donÆt understand all of this talk about spacers, larger throttle bodies and what not. Let alone the whole concept about what they are intended to do (high RPM performance increase), but the hole throttle body is already larger than the hole in the intake manifold, so unless people are going to the trouble to machine out the inlet to the manifold, it really doesnÆt make sense, not that it ever made sense in the first place.

Just my 2 cents.
