Injector swap question

[red454]

I'm swapping out the stock injectors for a set of 60lbs Siemens and noticed the little cups in the intake manifold. Is it best to leave these here or remove them? It looks like the cup might restrict the spray pattern with the new injectors. I believe these cups are used to prevent build-up on the injector.

If your talking about the caps that were on the end of the stock injectors remove them from the manifold.

Thanks, the last one had the cap attached to the injector. I thought when they were free in the manifold they might need to stay.
