Great addition for the engine bays of my 370z's! Some tips for my Z peeps. Step 1: remove the dipstick from the car & clean the oil off Step 2: use a vise grip pliers or clamp, C clamp or bench vise to hold the dipstick in place (I placed my C clamp at the top of the dipstick where the 2 circles are) Step 3: I used a $10 hand hacksaw from Amazon to cut directly underneath the top yellow tab Step 5: leave enough metal to have enough protruding so you can slide on the new cover. Enjoy!
