Just like to know what it the main function for the secondary air valve?..I have seen the some has remove it, can anyone tell me what if I remove it does it effect any problem to the engine.

 

It is used for the SAS or anti lag. It's an inactive system that you can remove. Homologation rules in rally require that the production cars have the same parts as the rally counterpart. I have been looking to buy one of the systems...pm if you're willing to sell

 

Thank you for the response, so it can be no harm to the motor i.e it won't stall etc.. or no effect to the performance of the car. The two bolts which are at the exhaust manifold can be replace with other bolt just to close the hole. anyone know where I can get those bolts.
