It is amazing how different some of these forums can be. 1addicts is completely against filters like this, but others I am on show gains of 6-8hp almost every time. I am gonna say this, drop ins flow more air, plain and simple. Do they flow more dust too, well I think it depends on the brand/quality. I actually wondered if they were filtering ok on my Lightning and I went ahead and sent off oil samples to blackstone, the results showed more than adequate filtration. I will use a quality drop-in in every car I buy, they flow better and last longer. If you are worried, send off your oil sample.
