The Hybrid Racing Dipstick sits flush with the valve cover, for improved hood clearance and sleek styling. It is easy to remove when hot or under pressure with the built-in T-Handle. The design uses a stamped steel measuring stick that allows for accurate oil measurement with OEM durability. For added security, we use a neodymium magnet that prevents it from pushing out when crankcase pressure gets too high. And to further simplify the entire product it is compatible with both K20 and K24 engines. One stick fits both engines.
