I have an s4 car came with an s5 engine. This is my first rotary so I painstakingly cleaned up my engine bay ditched the rats nest and swapped the front timing cover, water pump and housing and the throttle body lol. However, the entire intake is still s5. I'm trying to delete all emissions and related parts. As well as retaining the s4 omp. what I need to know is which block off plate kit do I need?
