should i need a nitrous filter or use stock gm piece spraying a 200 wet shot,i have a racetronix kit with hot wire and 42lb injectors?

 

I am kind of confused by the question. Yes to the nitrous filter.
Here is a good one that you can take apart to clean.

I like this filter kit as well. Has the option of using a -6 line into the filter to avoid any feed issues with smaller lines. Also completely cleanable. If you don't already have any other accessories, I would recommend taking a look at our all-out kit. It features everything you would ever need for safety and consistency.

Still run the stock filter for the fuel side as well.
