If you want to tone down the snappy throttle on your Holley Sniper EFI, the Sniper Throttle Extension Lever is the perfect addition. This simple lever alters the linkage geometry and slows down the rate of opening of the Sniper’s throttle blades. This makes for smoother acceleration in your cruiser, hot rod, or off-road vehicle. The Throttle Extension Lever is also compatible with MSD’s Atomic 2 EFI.
