OEM Biss Screw for the Throttle Body 3000GT/ Stealth / GTO

Genuine OEM Mitsubishi BISS Screw – Throttle Body Idle Speed Control
 
This is a factory original Mitsubishi replacement BISS (Base Idle Speed Setting) screw for the throttle body. Over time, the original screw can crack, loosen, or go missing, leading to idle issues and unmetered air leaks. Replacing it with a genuine OEM screw ensures a proper seal and reliable idle adjustment.
