Product Description
Similar to the stock, OEM plastic and aluminum radiator, this direct replacement radiator features a much thicker core for better cooling and heat dissipation. The stock 300ZX NA radiator is a puny single row design and can be inadequate when pushed to cool track driven Z's or those operated in extremely high heat / humidity climates. The Z1 NA Radiator is a much more robust single row design adding nearly twice the cooling capacity at a far less price than an OEM Nissan Radiator.
Each radiator includes a manufacturers 1 year warranty.
The stock fan shroud and radiator brackets will bolt up but slight modifications to the sides of the radiator and shroud may be necessary.
The Z1 Dual Electric Fan Kit will bolt directly to this radiator (custom wiring required).

the statement is made, "The stock fan shroud and radiator brackets will bolt up but slight modifications to the sides of the radiator and shroud may be necessary. " Can you be more specific as to the "slight modifications"?
The metal channel on the end of the radiator will interfere with the plastic on the shroud so a little trimming on the plastic shroud may be required. Also a slight clearance on the shroud around the mounting and ports may be required. Generally this is pretty quick work.

Works great!
Had to drill 4 holes in radiator aluminum frame to match the shroud holes, but once that was done it fit without any further modification.

I recently upgraded my 1994 Nissan 300zx with this Z1 radiator, and I couldn't be happier with the results. This radiator is a game-changer! It keeps my engine running cool, even during intense driving sessions. The build quality is exceptional, and the installation was a breeze. I've noticed a significant improvement in performance and peace of mind knowing my engine is well-protected. If you own a 300zx, this radiator is a must-have upgrade!

Took a bit of work to attach fan shroud. Had to cut plastic nipples to fit in stock location with stock hardware.

solid replacement for the oem radiator however the radiator fans z1 recommends pairing with this are terrible and the plastic holding the fans brakes within weeks and needs to be epoxied.
