Interesting article regarding intakes...

yes!.....some go dyno their stock car, then dyno with an intake...i wanna see the results, cuz i want an intake.
o0 yea with my hks exhaust my car is now faster in the low end and it pulls more on high-end too..so far i have seen gains, but they werent dramatic, but the gains were there..

I can notice changes very well in my car, I even felt the difference after tuning with stock intake, even tho it was only 2whp (but that was almost constant across the board, not just at a single rpm).
How's the iceman doing? That thing looks sorta similar to stock with the design.

If anything, less restriction in the intake charge at lower rpms would cause air to move more slowly, resulting in lower torque. Why is it that company dynos never include torque or a/f readouts, and only hp? It's a marketing trick. Customer sees that an intake gives 5whp, buys it, then realizes he only gets to feel that power for 1 second before shifting. Or if it's for a daily driver, he will only feel the negative effects down low.
if your torque went down, so would your horsepower, since the 2 are directly related to each other.
now, on an intake, most do not give gains in the very low range of rpm on the honda or other high revving 4 cylinder engines. usually you may see a SLIGHT loss of hp from say 0-2500rpm. But from then on (which is midrange and up) you will see a slight gain in both torque and hp. and the point there is if you are looking for that few extra hp for performance, then chances are it's for racing. and where do you spend 95% of your time racing? in the mid or top end range of your rpm. so for someone who wants the performance, a slight decrease or no change at all in power in the low rpm range is negligible and worth the gains in middle and top end power.
now whether or not it's worth it to someone to have that extra 2-5hp depending on where they are in the rpm range is up to them. but also, many people like the sound of the aftermarket intake. and buying one from a known vendor like AEM that does their research and development, is worth it since they get the sound and the added few horsepower.

I had an aem intake and I know it didn't give all the power they claimed. Have you seen the dyno they posted for an auto ex with aem sri? It was something like 6-7hp gain from stock. I sure hope you don't believe that one. I guess they must've had huge fans blowing cold air on the engine.

no i dont trust dynos from the manufacturer. i only look at real world dyno's from drivers or magazines that are building project cars.
i sure as hell dont believe 6-7 peak hp gain from stock with an SRI on a D17. lol. i'm with ya on that.
also for the most part, SRI are kinda useless in terms of performance. it's a CAI that will get you that little extra power.

Agreed. I've been in 6thgens tho with the same mods as I have and the car pulls so much better. What is it that makes everything work so much better on those cars? ulev vs lev or is there more to it. Better engine?

It was simply the way the engine was designed. pardon my lapse, but I'm pretty sure the 6th gen civic was ODBI? (someone want to clarify?) so that may also have had something to do with it.
regardless, the D16 in the civic was simply built differently, and responded to mods better.
I'm sure that once honda finished the initial building and engineering of the engine, they had to detune it more than the D17 for example. I'm not completely sure why the manufacturer's detune them, however I'm sure it has to do with getting the car at the power they want it at, for its purpose and design, as well as staying within the limits they have set in the ECU for a/f, etc.

I could tell the d17 isn't detuned much. I only gained 2whp with ecu tuning with somewhat heavy mods. It's really hard to squeeze extra power out.
hmmmm
the reason why i bought just a cheap ebay intake was cuz i heard from the members that even with an aem v2 you only get small gains.
the only thing i see that different from a cheap generic intake and the v2 is that they put in research into it.
so you think my stock intake would perform better than my ebay one? im thinking it will after reading this thread.

I agree with gearbox, I had the K&n fipk II in , all I gained is noise, nothing until 4800 rpm's, which is exactly what the dyno shows, I like low end , gettin off the line, I don't like losing any low end! I don't drive up at 5000 rpms all the time. So, the fipk is the supposedly the best for our cars....I sold mine, and like having my K&n drop in filter. I like my K&n drop in best (I know you don't like it gearbox), I keep it clean and oiled to trap the dirt...It helps a little with gas mileage (I think) and gives 1/2 hp!!!!!!!!!! yea!!!!!!!!
