Just like our Fk8 manifold the Accord/RDX gets the same treatment. Hp gains when tuned are similar with an Fk8 turbo on an K20c4 engine. All manifolds are puchased new and are Honda/Acura OEM. Our distributor we buy them from is supplied directly from the Honda Manufacturing plants. We do this because some sellers have 2nd tier parts. 2nd tier are parts with imperfections and/or issues such as parts shifted in molds creating less than desirable end product. When you buy from us you know it’s only going to be the best possible starting part and this will net you the best end product. Lastly on a ported cylinder head the effects are even more dramatic.
Gaskets are not included.
