Perfect fit.
This was the perfect size and fit for my Nissan Frontier. It was almost a perfect match to the OEM part and at a good price. So far, holding up well.

Great replacement
Fits perfect on Altima 2012 2.5 engine. I lost the original yellow one and I like this one better because it has the loop that secures it to the tank and doesn’t fall off.

Perfect match!
Fits perfectly on my 2014 Nissan Altima SV 2.5. It’s an exact match. Definitely works for replacing the old ones that are broken after years of use.

2018 nissan pathfinder
Fits. Hopefully lasts longer than stock. Stock part is pure crap. Have 2 2018's and both have caps that cracked - you know or you wouldn't be reading this. Have 2 more of different years I have looked at for family members - all cracked as well. ANYTHING is going to be better than the Nissan part. I'll update if/when these fail....

Replacement cap
Needed to replace a radiator reservoir cap that somehow went missing. As soon as it came- popped it on. Fits perfectly . What’s nice it has a little extra so it’s less likely to go missing because the cap worked it way off.

Quedó perfecto en Altima 2014
Está mejor que el original, trae un asa para que al destapar el tapón no se caiga o pierda. Se siente de buen material (mejor que el original), ajusta firmemente a la rosca del depósito. 100% Recomendable. Quedó perfecto en Altima 2014.

Right fir for Nissan Altima 2012
I got it for my Nissan Altima 2012 as the original one was broken. I received it so fast and it was a good fit for my car. I still do not know if it can tolerate the extreme cold weather here in Canada, but I will update my review after next winter. So far so good!
