I haven't read the actual article, but I think it was the base model, not the RXS-s. My 5th gen Prelude would not benefit much from a CAI, since it doesn't increase the power by more than 5hp. The point is untill you dyno your car you won't know for certain how much hp you gained from a CAI. In some cases the increased noise might make the car feel faster, when in reality it may be almost the same. Cosmin >> Stay informed about: Prelude fresh air intakes do they work?

I'm mainly looking for more miles per gallon than outright power. Any noticable improvements found out there? >> Stay informed about: Prelude fresh air intakes do they work?

It might be even more restrictive;larger displacement of the 2.0 L Prelude compared to the 1.8L of the GSR. In referring to my noticeable increase in power,I refer to the seat-of-the- pants feel of accelleration,not noise. -- Jim Yanik jyanik-at-kua.net >> Stay informed about: Prelude fresh air intakes do they work?

Feather-foot it.Narrower,harder tires get better mileage. The intended use of CAIs are for more power,not fuel economy. -- Jim Yanik jyanik-at-kua.net >> Stay informed about: Prelude fresh air intakes do they work?

he has to mean the psycological experience of getting less gas mileage. You know, the one where you bolt on HP and then you feel you have to drag race from light to light. The constant mashing of the accelerator will surely cause poor gas mileage!!!

Yes they definitely work, my boyfriend used to work in a performance shop. The best is using a cold air intake, preferably by AEM. If not then just a short ram intake will be good. Adds horsepower.

I put a short ram intake on my 2000 Civic SiR and didn't really notice much other then major increase in noise... but i must say that I really like the new sound, exspecially when VTEC kicks in. It scares the hell out of people. "test" wrote in message > Yes they definitely work, my boyfriend used to work in a performance shop. > The best is using a cold air intake, preferably by AEM.

I just noticed your reply to my post. I said a CAI would make the car less fuel efficient because it allows more air into the engine. Since the mixture ratio should be constant, it makes sense that there should be more gas going into the engine as well. if only the air intake would increase but the gas would stay the same the car would run lean. If this reasoning is wrong, please correct me. Cosmin >> Stay informed about: Prelude fresh air intakes do they work?
