Been offered a prc inlet off a jdm ep3.
1 will it fit direct bolt on like for like? If so how easy?
2 will it make any difference before mapping?
3 it's safe to run on std ecu? (I've got a dc5 manifold and cat too BTW)
4 what gains can be expected once mapped?
Thanks
I know the rbc and rrc are better so please just keep it specially to the prc
