AIR INTAKES,WHY? - Page 2

i put a cold air intake on everything...

Like ive said b4 ive had all 3 aem intakes ( SR CAI and now V2) CAI was one of my favs but im soo in love with the V2's sound even though in the upper rpm its louder than my greddy evo2 exhaust

Also, of course you've heard the colder the intake charge (the air) the more power is yielded inside the combustion chamber. Hence the reason for nitrous shot into the intercooler or the cryogenic intake charge system.

Hot thread Gentlemen: I think I will start with teh AEM V2 Right away, as a reward for doing the belts, FuZion HRi's are in the mail - is there any greater anticipation than waiting for parts? Essencially it sounds like headers, exhaust intake is nice, but really all that work is prep for the installation of a turbo - True? If I were to look at a turbo down the line is there any ENGINE mods I'd need to make outside of what is listed above?

Speaking of Gas mileage.
I'm truly a novice at modifing cars, shoot I just installed my first set of Ignition wires on the 1991 accord and my mpg shot up from 23.5 to 26.04mpg. I was impressed by the change, going to flip out the rotor and cap this weekend.

Thanks,

From another "true novice" A: what are the ignition wires, rotor and cap?
B: What does changing them out do for me? (you sparked my interest)
C: What does it cost?

A header would have to to be removed for turbo and a turbo manifold would be installed in it's place. Mods are intended for the goal of the engine. Such as an exhaust for turbo is different than an exhaust for an N/A car. An intake would also be removed and a different intake would be needed for the turbo.

EDIT: Also, builing an engine is often suggested. Please view the link in the "GOOD TURBO INFO" thread for more on building engines. $$$$$$

Thing sin your ignition system get old and need replaced because they are not as efficient as they used to be ignition wires are the wires that connect the spark plugs to the distrutor cap. The cap has a rotor in it which sends the spark through the wires to the plugs and therefore causes combustion. Changing them is maintenance more than modification. Wires can go from $30-90 depending ont he wires and what type of ignition and engine they're for.

I noticed a positive change when I replaced my ignition leads and spark plugs, however my cars mileage was high and had stock leads and plugs.

some companies claim thier leads and plugs can free up a little BHP, but i dont really believe it-

They replacing things like they do nothing but restore lost hp. If you added new oem plugs you'd feel the same results.

If you plan on turboing defiantly dont waste money on headers an intake is a bit cheaper and id spend the money on one now even if i planned to turbo Another good mod is a grounding kit it doesnt add any horsepower but it frees up existing HP thats been lost over the years do to normal wear and tear on the electronics of the car.

Some grounding kits, w/ voltage regulators are better a little better. A'pexi had the best dyno number in a test conducted by one of the magazines. Can't remeber which one. Hondas generally have good stock grounding, but it'll help anyway. Don't start looking for 10hp though. Plus you'll get better results from a grounding kit w/ a turbo...since you won't have to remove it.

i see the cold air intakes on ebay. are they worth the money and will they make any kind of difference? or would they basically be a waste of money?

They're not a waste...the only difference between ebay and AEM or Injen is that they actually had R&D for the applications and some are DOT approved. Other than that they're all just a damn pipe that flows better than what the factory put on there...and sounds sweeter too. You may get a 1hp difference between intakes..if any at all.

I thought that they do give you better milage if you drive normal but if you start flooring it then your mpg will go down.

thats because the air intakes are designed to maximize airflow in ur intake manifold. if u run the piss outa your car, the gas MPG goes down... because the ECU has to balance out the fuel/air ratio. if your gettin more air.. you need more fuel to balance it out.. or else your cars gona not function properly

Good answer.

if i havent stated before, i have an "ebay intake" on my car...and with a K&N filter hooked to it instead of the cheap paper filter, it is every bit as good as the AEM unit, which costs 175-200 bucks more.

I would tend to disagree depending on what type of change you did to the intake.
If you have it set up in any type of ram air or more freeflowing the car will see the increase and adapt to it to keep it from going lean so it will increase the gas flow to match it. You see more power but probably less gas mileage. Changing the temp of the air while keeping the flow the same may increase the gas mileage.
If all your after is better gas mileage changing to synthetic oil in both engine and trans, and cold air intake (maybe) and a better exaust system is about what you want to do. There are other ways also like different type tires.

I bought a full CAI off ebay seems to be great as far as ga mileage i dunno if it increased or helped but if u want better fuel economy running like supreme rather then regular will help you get more mileage you pay a little more but u get bettere mileage

The gains between the two aren't worth the price difference, unless your squeezing for hp that hard and have the funds to dish out. Be proud.

The filter is more important than a pipe.

A CAI inst much more money then a ram intake though id go with teh full CAI it actaulyl does give u more hp then the ram i tried the two i borrowed my buddys ram and then i bought my CAI and i noticed a dif...

i just went with the comptech ice box intake, it's one of the more pricier items on the marketm but
it looks stock, is deisgned to fit perfectly in my vehicle, at 3500 to 4000 rpm i can feel the intake drawing the air in from below the engine bay, and as a bonus, it actually has a nice deep tone at that rpm range.
of course below 3500rpm, no effect, thats vtec for you!!!

im not an engineer, but i do spend a helluva amount of time driving every day, hence, im pretty in tune with how the car car is perfoming. this mod has made a mild difference, when vtec changes over
at 3500, i now have better acceleration and i can feel the power gains thru the 6500rpm when i have the car if third, i have the manual tranny, 4th gear or D in my car is no fun!!!


gas mileage of course has suffered, however this is what i wanted, higer performance means economy be damned in my book!!!!

lets see what soem headers a high flow cat and nice cat back sytem will bring

everyone in here that thinks an aftermarket intake (ram or cold air) gives you better gas mileage is a complete idiot. more air means more fuel used, which means LOWER gas mileage!

way to pull up a 2 year old thread. to change the amount of fuel used, you would need to tune the car and tweak the ECU's fuel/air ratio. this cannot be changed any other way. what gives you more power isnt the increase of fuel of course, its the ease of moving the air. youre increasing efficiency. if you have ever lost mpg, it is most likely due to an inferior air filter.

It increases the mpg from better flow, better tuning, and its lighter than the oem intake.  The only way you lose mpg is what Velocifero said and bc you want to hear the throaty sound all the time.
