Product Description

Z1 Motorsports High Pressure Radiator Cap for all Nissan and Infiniti models including the 300zx, 350z, G35 and 240sx.

By increasing the pressure within the coolant system, you can thereby lower the boiling of coolant itself.  In other words...Your car will run coolerLocated on the radiator, the Z1 Motorsports High Pressure Radiator Cap replaces the stock cap which has a factory relief pressure of 1.2 Bar (17.4 PSI) with a relief pressure of 1.37 Bar (19.9 PSI).

Produced with OEM quality, but with the performance advantages of an aftermarket radiator cap.

Sold individually.

Fitment is perfect, Cap looks great, and the price is only a tiny bit higher than OEM which is excellent.

Excellent cap, good piece of mind for those hot summer days. Only issue is the sticker on top did not last long, no big deal as I covered it with a cap finisher. Otherwise it's been great!

ok heres the deal. love what i got but you will not see a tempature drop unless you have a quicker opening tstat like mishimoto as well as an all aluminum rad or a larger one. also if your rad is a bit old and you like to get on it a lot you run the posibility of cracking the plastic fill neck on the stock rad. exactly what happen to me but not mad at all about it. of course higher pressure means risk of weak points breaking. also one the coolant will boil off when the cap does open up so watch your collant level especially if you like to push your car like myself. great product but a good idea to purchase supplemental upgrades with it to take full advantage of what this cap offers! this is i believe the highest pressure cap you can get for a stock rad and im literally looking for radiators that have a stock style neck so i can make sure i use this bad boy lol. love it! have the mishi tsat now and gettin rad soon then will install all at once and ill be comfortable knowing my engine will literally never over heat no matter how hard i drive her unless some other unrelated part goes like a pump or belt. just fking buy it already bro lol

Great product. Had on my car for almost 15k, nice cheap upgrade. You've spend $20 on something worse. Highly recommended

Excellent construction. Definitely tighter spring tension. Recommneding upgrading/replacing all old worn out hoses to avoid any unexpected coolant leaks.

Great Looking Radiator Cap. If I'm not mistaken has the highest relief pressure rating out of any radiator caps I've seen. Great Job Z1!
