Hey civinfo, I have deicded I am going to order a tegiwa manifold and hondata flashpro, I was wondering if the FD2 Throttle Body & RRC Intake manifold would also be mods worthwhile to buy? Is the power increase worth the money? I currently already have a milltek cat back and HKS RSK. Want to ask you lot before making my decision as I dont want to spend the additional money if its not going to be worth it! thanks.
