I just ordered a cobb accessport v3 I plan on running stage 1 I only have a evo x bpv a injen uicp and a k&n drop in do I need to put the stock filter in yo run stage 1. I plan on getting a Cai and cat back in next few months but for now can I go with just the drop in?

 

That should all be fine for stage 1. If you plan on getting a cold air intake, none of the stage 2 or 3 maps support cold air intake so there is no point unless you plan on getting a pro tune...

 

Im running a short ram on my RA with stage 1. don't recommend it unless its pro tuned
