Does a N20 filter restrict flow at all??

 

Only if they are restricted with debris. That is why we have the larger inline filters which can hold more debris without restricting flow.

 

Thanks.

 

ALL nitrous filters are restrictive. Any thing that is placed in the flow-path will create a restriction.

 

as I bought my TNT kit used,I dont know how bad the NOS filter is,but I used somebody elses bottle that would not work with the fitting on the filter,so I just took it off,gained nearly 3tenths.Who knows maybe time for a new one

Hmm, I was wondering because my friends are dynoing 50-60 rwhp more than me. I can understand about 20 because they are M6's and I am a A4.
