Efficient cooling is critical on the twin-turbo Z32, and the upper fan shroud plays a key role in directing airflow across the radiator. The genuine Nissan Upper Fan Shroud (part number 21476-40P00) is the factory plastic shroud designed specifically for Twin Turbo Fairlady Z32 and 300ZX models. It sits above the radiator and cooling fan, channeling air for maximum cooling efficiency under boost and high-load conditions.
Original shrouds frequently crack, warp, or become brittle from heat and age, reducing cooling performance and allowing air to bypass the radiator core. Replacing a damaged unit with the genuine Nissan 21476-40P00 restores the correct airflow path and helps maintain stable operating temperatures. Catalog sources confirm this shroud is for Twin Turbo models only (VG30DTT / VD30DTT) from approximately 1990–1996. Naturally aspirated Z32 models use a different shroud and are not compatible.
Whether you are refreshing the cooling system, replacing a cracked factory piece, or completing an engine bay restoration on a Twin Turbo Fairlady Z or 300ZX, this OEM upper fan shroud provides the proper fit and function. At Terra Firma Automotive, we supply this genuine Nissan Upper Fan Shroud for Twin Turbo Z32 owners who demand authentic cooling components.
