Sold individually so you will need to change the quantity in the cart for your application. If you are buying for a 3SGTE 4cyl engine with 4 valves per cylinder making a total of 16 valves, you will need 32 of these locks because 2 will be required per valve. Take the number of your valves and multiply by 2. For a 2JZGTE/GE engine you will need 48 of these locks for a set.
