Guys, i have installed a cold air intake in my civic 99 SOHC but the car performance is not well , high sound and RPM with low performance . Any advise plz ?

ezone

Were you expecting a rush of newfound horsepower upon installation? (Not gonna happen.)

Noise with CAI, yes. That's expected.

Reinstall original equipment, see if it still runs as bad as before?
Is there another problem causing it to run bad?

Hani4g

Performance is better with the original intake , i know the sound should be higher but the performance also should be higher . Is there any nodification needed to perform well ?

Mikeyyy

how much performance was you expecting??

which Cold Air intake did you install??

ezone

You know those funny boxes pipes and chambers that are attached to the stock intake tubing, they look like they do nothing useful except take up a lot of space....those are there for a reason.

Some of those are designed to quiet the intake noise.

Other chambers are tuned to take advantage of natural pulse waves that occur in the intake, increasing torque in certain RPM ranges.

Hani4g

The performance is lower than the original intake , im not expecting much performance from the new intake 2 to 3 HP maximum . My concern is the car performance is going negative not at least the same.

Read again:
You removed this when you removed your stock intake.

Listen to ezone. Trust the Honda engineers, not the aftermarket company.

Hani4g

Thanks for the advise ,
Is there anyway to fix this or shall i return to the stock , and why most people are installing this cold air intake if its affect the performance negatively!!!!

ezone

I think you already know the answer.

Ask the 'most people' that do it.


More noise = more performance?

Wankenstein

Short air intake: little to no to negative gains

Long air intake: same as short air performance but, increase chance of engine hydro-lock.

Stock: best

Just intake = more noise, not much gains if not negative.

Mine were the same, but still wonder how my camshaft would behave without the intake / header.

Oh, well, I am not gonna install the stock intake back just to test. I like not needing to change the filter and throw the old one.

Perhaps try an ECU relearn after installing the intake, and make sure your MAF OR MAP sensors are plugged in, clean, and that the wires aren't broken.

my k&n cold air intake gives me more horsepower, motor runs cooler and is very quiet on my civic coupe ex 2003 vtec

Dyno results comparing before and after?

Mad Dog Tannen

What brand of butt dyno did you use?

StormBringer

i use no such device. they are rip offs. the cooler temp is from the gauge. quiet motor from my ears. more HP from stop watch.

Wankenstein

So you're using your guess-o-meter?

Placebo effect to justify the manufacturer duping you into wasting your money.

StormBringer

no, im using devices, i believe i made myself clear, at least to most here. the temp gauge stays lower, i can obviously hear that the motor is quieter. the stop watch tells me power/speed in acceleration is better.
i don't spend money on foolish and to me phony devices such as dyno butts.

Wankenstein

Temp gauge has nothing to do with air intake. Engine quieter has nothing to do with air intake. You must be measuring in milliseconds (or less) as far as gains.. Please stop talking nonsense, as the OP has already come to his senses and converted back to stock.

StormBringer

once you think you know a thing you become closed minded....im done with this cold air thread. ..believe what you will.

wise words. when applied to yourself, even wiser at best, with other mods, they will give what, 5WHP? measured in a dyno.

PS: you did not waste money in butt-dyno?!? ...

...

...

recommend getting even wiser and use the internet to find out what that expression means, please...

seriously...

Wankenstein

SB: you seem like a good candidate that would waste money on this...lol:

Found it!


Butt Dyno

$529.95

Just install a great mod like a cold air intake? Electric supercharger? Big Muffler? Magnetic fuel line ionizer? Awesome wing? Are you getting no respect from your friends for your newly found power? As we all know, these are high end and sophisticated modifications. Some may be TOO sophisticated to actually show up on a traditional dyno. So here we have: The Butt Dyno. Simply place it in the seat, and drive fast, weaving in and out of traffic. (On a race course, of course.) Now you can tell your friends with confidence "That oil-saturated air filter gave me 20 horses!"
