Do Nismo Injectors Come With O-Rings?

[Torques]

Hi there,

As per subject:

Do side-feed injectors come with the O-Rings or do I rather have to buy these separately?

Thanks ..

You gota buy them separatly.

I think so, but u can swap ur old seals over if ur careful. Otherwise take the old seals off and get them matched

Just get them from Nissan. A lot easier as they are a specific size that you won't find at a parts store.

given how cheap it is just replace them and remember to use petrol soluble lube when installing them.

Yep bit of vasoline never hurt anything ?

Hi there,

The O-Rings are in the mail, so next thing would be installing the new injectors.

I have not done this before, so is this reactively straight forward?

Also, can the plenum stay in? Any tips appreciated ..

Thanks ...

Plenum can stay in, just be extremely careful when pulling the rail out and don't force anything or you'll break shit. The most important bit is don't round the phillips screws that hold the injectors in or your in for a shit time, soak them in wd40/rp7/whatever you have and use a screwdriver that fits properly. Once you have the rail out and the injector caps off its pretty easy, lever the old injectors out with 2 small flathead screwdrivers in the slots on the sides, put the new o-rings on the new injectors, lube them up and drop them in. Don't do the caps up too tight either, they only need to hold the injector in and not come loose.

With the Phillips head screws, I found its a lot easier to use a pair of vice grips to crack them off, then use a screwdriver. Very easy.
