The K-Tuned Billet Oil Dipstick was designed to follow the exact contour of the OEM valve cover, giving it a smooth, shaved look. Along the bottom of front edge is a small flare, which is just enough for removal. Look closer and you'll notice a small hole located at the center of the flared front edge. This can be used to attach a spring tie down on boosted applications where increased crankcase pressures can blow out the dipstick.
