CAI vs. K&N filter
Does anyone know the differences in horsepower gain between CAI and a K&N filter. I think the price difference is about 50% or $60 vs. $120, if I'm correct. So if the CAI ourperforms the K&N filter by more than 50%, I guess it would be a good buy.
Anyone please let me know!
Gotta change my air filter, so I mind-as-well upgrade!
Thanks in advance!

*CAI - you should get around 6-8HP or so
*Drop in Filter (K&N) - maybe 1-3HP
The K&N just replaces the stock filter, so you're still using the stock intake setup.
The CAI replaces the whole intake setup with a 3" pipe and high flow filter, right to the throttle body.
If you're looking for better gas mileage, go for the K&N. If you want more power AND better gas mileage (if you can keep your foot off the gas
), then the CAI is the clear choice....

I had the K&N in my car, and I realy did not feel any diff, not even in the sound. It should give you ~2hp better gass mileage.
The CAI, ~8 hp and also better gass mileage if you can keep it under 5600rpm .
The CAI sounds amazing, I would get the CAI just for the sound. The K&N is a wast of money IMO.
And if you want the K&N I havea used one (~5k on it) I'll sell.

Well once I heard that the CAI produces a nice sound plus gives much more horsepower, I'll take the CAI.
What's the best brand? Are they pretty much the same (Injen, AEM, etc.).
Thanks for the info folks!

There is an endless debate on AEM vs. Injen.. search for a more detailed discussion.
They are both quality products and seem to produce very similar results..
My AEM was $205 w/ overnight shipping.

I'm sure the next question will be about the Bypass value.
It is NOT ABSOLUTELY nessecary... many members have it for piece of mind. I decided not to go with it.... just don't drive through any standing water or deep puddles when accelerating and you SHOULD be fine... don't take my word for it though, do a search and read everyone's input, then make your own decision.

I live in Cali for the only water my car sees is during a wash! An if it rains its very mild!
So if water were to pass through to the intake, what would be the worst case scenario. The engine would hesitate a tad while it burst the water it took in?

You could Hydrolock,... blow you engine by bending the rods, cracking the block, and a whole mess of other things. You would need a new engine = $6,000
Water does not compress, and if it gets into the engine, something's got to give.
AEM has a great article on their website

I'll consider it new engine insurance against water intake!

many claim the Bypass negates some of the beneift of the CAI because it allows hot air to sneak into the intake from inside the engine bay.. again.. read up on it.
There have been ZERO reported cases of Hydrolock ever actually occuring on a CL, but i suppose it could happen

No kidding.... Ever since I got my CAI, my FOOT has gotten alot heavier.....

acutally according to the k&n site, the filter yields no additional hp, it simply increases fuel efficiency by 2mph city/4mph highway. I have the filter and that has been my experience

I had the AEM cold air and it was ok. I did not feel much of a difference. The sound is good, but not I think the Injen sounds better. As of right now I have the K&N filter with the resonator removed. Sounds just as good and has helped the mileage out pretty well. I don't think the intake is worth $200. Save for headers and get the K&N and remove your resonator is my advice.

Exhaust and Intake
The AC-R uses a custom 2.5 exhaust with no cat...when they race they just unbolt the exhaust from the headers. And about the headers...the header lenghts are not as short as the comptech ones...and by the way the headers were made by DC Sports for Honda as a custom job.... DC Sports will not make them.
Now the intake...honda said they experimented with various cold air and short ram intakes...but theres works the best. What they did was take out the resonator...use the stock air box with out a filter and they used like a big piece of plastic tubing from the box into the throttle body (it looked like a modified Iced Tea pitcher).

that's what i did, but i replaced the resonator w/a 3" hose like the icebox. the intake sounded like an ufo w/o the resonator, but that went away w/the installation of the hose.
