Series:A/Model/AE80/82/How To Identify A Series 3 Twincam
This is a simple guide used to identify if you have a series 3 twincam.
1. "Red and Black" writing on the cam covers (would not rely on this on it's own).
2. The lack of an air intake temp sensor in the intake manifold, it is in the airbox instead.
3. Drivers side strut tower has a funny looking heat sink with a large yellow plug, this is the resistor pack for the high impedance injectors.
4. The injectors are pink with rounded rectangle plugs.
