Throttle Body Cap Kit - 1050/1090/1190/1290/1390 (ALL)

Works really. good

These are cheap insurance when you are performing any maintenance with the intake has been removed. These will keep trash from getting in your engine.

You don’t have to worry about hitting or moving a dirty rags and spilling debris into the throttle bodies.
