Sorry but i'm a bit behind with the upgrades. I've just upgraded for race 3&4 using the ECU plus the mandatory ones. Now for 5&6 am I allowed to add the manifold and Filter or sports cat in addition to the ECU?
Gary is right. The air filter and intake manifold come as a set, as do the exhaust manifold and sports cat. The ECU is a stand alone upgrade. You can use any combination of these uprades, as long as you only choose 2 for the next 2 races.
