So, i was looking at my dsm injectors, and then one of these little caps fell off. It cracked in half. I then examined the other injectors, and on 3 out of 4 they are cracked to a degree.

now my question, what exactily do they do, and can you replace them? They look like they might help to create the spray patten, but im not positive. Any assistance would be greatly appreciated.

 

Many people say they've ran them without those caps, but I didn't want to do that. Places that clean injectors will also replace them at no additional cost.

 

Im running my rc's without them, everythings fine.

 

awesome. thx for the input.
