blinx's official guide: which intake really is the best? i answer it.
So I’ve been thinking lately, a lot of people ask which intake (induction) setup is best, there are a lot of great ones like: mugen, aem, arc, j's, etc... And we always wonder which is better, which is best, that’s always the question "which is best" well im going to answer that, well kind of
Before I go on I just want to say this is not a debate about brand, nor is it a debate about cold air feeds vs short intakes etc...
just like cams, an induction kits performance will depend on other mods, for example if you buy an AEM intake for you civic you may think its great when the motor is stock, but later if you build the motor up it may become restrictive, intake systems like (exhaust systems) are mostly designed for stock to mildly modified vehicles after all they are designed on stock vehicles and all the research and development is done on a stock vehicle.
So now we have a problem, we have an intake that was designed for a stock car, or perhaps a mildly modded car, like with just header/exhaust/decat/ecu. What happens when you get that stroker kit or a ported head, or maybe some cams, or even all of those, then what intake do you use? Well here is the simple answer: you go custom, seriously it’s not as hard as you think.
Most intakes are 2.25" and that works great for a stock motor, but for a motor that has a lot of mods like cams or whatever something bigger is in order, I personally have found that a 3" pipe works A LOT better for most b series engines. just like I described velocity in regards to exhaust flow in my exhaust thread which can be seen here: http://www.ek9.org/forum/air-intake...velocity-backpressure-all-explained-here.html intake flow can be described the same, a smaller pipe will give you that ideal velocity at a lower rpm, a larger pipe will give you ideal velocity at higher rpm. Pipe length also plays a role, a longer intake pipe will give you more top end power while a shorter pipe will give you a little midrange boost, anyways im sure there is some complicated math formula to decide the perfect length and diameter for your intake pipe but im not going to get into all of that.
So now the true answer is there is no such thing as "the best intake" only a good set up for what you have. I personally think most people on this forum will benefit most from a 3" pipe with a velocity stack and filter on the end.

BLOX Aluminum Velocity Stack - JHPUSA.COM Serving JDM Since 1999
For the BPI stack you can use k&n filter part number RF-1048, the blox stack has a filter that can be purchased with it also made by blox, im not sure if the rf-1048 filter will fit on the blox stack but it should.
as far as getting a 3" intake pipe you can have one made for you, its simple, if you cant have one made you can always buy a cheap short intake made for a usdm 99 Honda civic SI or EX off eBay (usually $40) and use the pipe from that as long as its 3".
Average cost of doing this is $150 (50 for the pipe, 50 for the filter, and 50 for the velocity stack) or less which is cheaper than most intake kits and better in my opinion.
I personally used the BPI velocity stack with the K&N RF-1048 filter when I was NA and I really liked it, blox now makes aluminum versions of that velocity stack for very cheap, I have posted up links to both above.
well I hope you guys find this a little bit helpful and may help your search for the best intake.
