EVO Idle Screw Block


Used on our EVO fuel injection system to hold the Titanium Idle Screw or a flexible Idle Cable (acquired from any stock throttle body).

This Idle Screw Block will replace the Stock Idle Post that comes from Kinsler. When you replace it, make sure the return spring is on the left hand side of the block when you tighten the block down. This spring is what returns the throttle plates closed.
