can cold air intake damage my engine? (1999 HONDA ACCORD COUPE 3.0 V6 AUTO)what bad points does it have at all?

I DON'T KNOW OF ANY BAD POINTS, YOU GET BETTER FUEL ECONOMY MORE HORSE POWER AND YOU NEVER HAVE TO BUY A NEW AIR FILTER.

no it wont hurt it at all,,and really there are no bad points to it,,it helps it run better,,and get better fuel economy,,it will also start better,in the mornings,,over all performance Will be a lot better on it,,i own a repair shop,,and have installed a lot of these,,all my customers seem to like the a lot,,and all have said there fuel economy got better,,so there really aren't any bad points to it,,good luck with it,,i hope this help,s.

Within reason, NO!The air filter slows the air flow to the carburetor enough to warm the air slightly, enough to eliminate the possibility of hurting the engine. Exceptions would include arctic temperatures, removing the air filter, tampering with the air intake.

Cold air intakes don't do any damage to your engine.The cold air intake device itself doesn't actually produce any power.You get more power from a cold air intake system because it fools some of the sensors in your air intake.Most modern fuel injected vehicles have a MAT (Manifold Air Temperature) sensor located in the air intake. When the MAT sensor indicates the air is cold outside it adjusts the engine's fuel and ignition settings to compensate. It adds more fuel to the fuel air mixture and advances the ignition timing. These changes give you more power.USE THIS TRICK AT YOUR OWN RISK!The manufacturers of these cold air systems don't want you to know this.There is a simple trick used on GM cars to fool the engine computer and achieve the same effect. With a little research, you can do the same with your HondaLocate the MAT sensor, usually located between the air filter and the fuel injection throttle body. Unplug the sensor.Install a 12,000 ohm resister across the connectors of the wiring harness plug. This will fool the computer into thinking that the MAT sensor is indicating the outside air is about 30 degrees F. The computer will adjust the fuel and ignition accordingly. I've seen about a 10% increase in power with this trick. Since the computer is getting a reading from the MAT lead, it won't even store a code.I suggest removing the resistor and reattaching the MAT sensor in cold weather though.

cold air should have no adverse affect, cooler the fuel air mixture the denser the air better the combustion. The trouble that comes from thermal shock to metals and such takes a much greater difference in temperture than you are going to encounter in this situation.

contrary as to what others on here say yes they can harm it...what people dont realize is the cold air intakes dont have the air box and baffling that the stock intake set up has....yes they do give a little bit more power but not enough to notice unless u do an aftermarket exhaust to....but where the harm comes in is when u hit a pot hole filled with water and it splashes on the filter in adverntly it sucks water in the intake....not good for an engine...if enough water gets in it can destry your engine....there is actually a honda service news saying not to install them but its up to you its your car i would not advise in installing one

Yes and No. Yes- say you are driving and you run into a puddle of water, the water goes through the intake to your engine turning your oil in your engine milky killing the piston rods...No- If you fabricate the parts for the cold intake so that if you do run over water and the water splashes under the engine it cannot get into your intake.

the only way you could hydrolock is if u were driving in over a foot and a half of water. And if you ever are driving in that much water, i think you have other things to worry about.
