anyone thought of using something like this

I know its a 3" inlet, but if I get a coupler that goes from 3" to 3.5" that could work no??

 

I actually found a 3.5" velocity stack which I think im going to get. I dont think anyone here is using that so ill be the first . If the srt ecu doesnt like the extra air flow that these things are supposed to provide then ill ditch it and get the neo.

fyi the stack alone on a h22 honda provided an extra 10hp.

 

APexi power filter has a vstack built into it. Vstacks are nice but some are pricey and others are cheaply constructed. They are good power adders though.

 

I have a Injen Intake for my GS300. I got it used and I want to replace the filter. What size am I looking for and what is the best bang for the buck? (OP-sorry to hijack it)
