For sound a HKS is standard for most, it roars and gives good gains once mapped.
For performance a closed box suits most such as GruppeM / Mugen / Tegiwa. They sound pretty much OEM but give good gains if fitted with a fog scoop and tract.
Third is a CAI, these tend to give best gains but some can be a pain to fit and you need to watch for standing water. CPL sits quite high compared to the rest but the battery needs relocating.
