Of course, if it comes with sims use them. whats funny tho.... when i installed my x metal mids i had the sims. my driver side rear sensor would not come out and it stripped when i got it out, so couldnt use it again. i tied it to the frame and stuck a spark plug in the open hole (spark plugs and o2 sensors use same threads) so i had one with a sim and one hanging, never threw a CEL and saved $100 on a sensor lol
