The kit ships with two gaskets, three alignment spacers and seven bolts plus small washers for a complete throttle-body-to-manifold installation. Finished in red, the part is 1-inch thick and designed to alter incoming air flow characteristics around 800–3,000 rpm where drivability gains are frequently experienced.\u003c\/p\u003e\n\n\u003ch3\u003eHow does adding a 1\" spacer change engine behavior at common driving speeds?\u003c\/h3\u003e\n\u003cp\u003eThe PQY spacer increases the volume and straightness of the incoming air column, which can smooth throttle response and bolster low- to mid-range torque.
