IRP Shifter Silencer Kit - For Miata

Love your IRP Short Shifter for Miata, but hate the road noise? Introducing the Spec13 Motorsports silencer kit! The wedges and gaskets act to suppress the "tuning fork" effect created by the slots in the shifter lever, reducing road noise associated with the IRP Short Shifter significantly. Installs in minutes and comes in a variety of accent colors or solid face. The kit includes: 4 x Carbon fiber-PLA insert wedges 2 x TPU gaskets, your choice of color (Green, Blue, Red, White, Solid Face) 4 x pre-inserted M4 nuts 4 x M4 Allen socket head screws ***PLEASE NOTE: These DO NOT work on the new, updated version of the IRP shifter. IRP has addressed the harmonics issue on the latest version and the slots in the lever no longer go all the way through.***
