i just got a skunk 2 intake mainfold for my ls vtec with a b16 head. my question is do u use the round plastic pieses that go under the fuel rail. they are big washer like things. cause if so my injector dont hit the fuel rail. im using stock b16 rail on b18 injector 4 now.

 

if i don't fit with them, take them off. make it fit.

 

I used a grinder to shave them down. And moved them from bottom to top.
