P38 gems dipstick

[nismoit]

I bought my 4.6 gems V8 engine without oil dipstick and tube and i must buy them, as i understood:

Engine equipped with secondary air injection Needs LQM100920 -715 mm lenght dipstick coupled to LQN101150 tube;
Engine without SAI Needs err4905 - 655mm lenght dipstick coupled to LQN101060 tube.

Which One i Need?

Look at your engine... does it have SAI fitted to it, or WILL it have it fitted when you are done with it?

Many thanks, without doubt It hasn't secondary air injection, so i Need short dipstick!

It shouldn't really matter, as long as you have the correct pair of tube and dipstick. The longer/different one is simply to get around the additional hardware on the engine versus more direct without the hardware.

There's also a variant for low emission zones in the US - which somehow I received!
These are basically calibrated with a lower oil level!
