CAI in the winter

hey all just wondering who else is in a frozen tundra part of the united states like me, well i have a CAI and this is my 1st winter with it and im wondering since it has no bypass valve and my splash guards are MIA should i just put the stock airbox on with out the resonator for the winter

no
you'll be fine

agreed. Although if you have a newer Civic the intake temp sensor could see so much cold air that it will dump alot of fuel into your car causing it to run a little bit on the rich side (cold air is more dense with oxygen).

yea i live in ann arbor michigan and i have a CAI and its fine. theres practically no way to get enough water around the intake from a splash to do anything. just make sure IF you do get water on the filter, it will freeze and damage the filter. a CAI doesn't cool the air enough to do anything to the engine anyway. it just takes cold air from outside the engine bay. if you had an innercooler in a frozen tundra... you have something to worry about...

ok so i guess the fact that i have been getting horrible MPG is due to the huge amount of cold air coming into my engine is there any way to fix that

Same here on the gas mileage, Mine has been very bad, any suggestions. Anyone......

if ur worried about the mpg put the stock airbox on. this will reduce the cold air which makes u run more rich than usual as stated above. this should help out b/c ur ECU wont continue to dump so much fuel in.

I don't know if resetting the ECU will do anything.

personally i wouldnt touch the ECU unless you are 100% positive of what you are doing and its long term and short term effects will be. no offence to the mod.

you can reset the ECU by unplugging your battery.
the computers and all that other good stuff will reajust its self.
nothing major but you will have to reset your time

*** with no harm to the car***

is there anything else that can be done other than resetting my ecu

try taking it one step at a time
a process of elimination

um ok all i can think about is resetting the ecu and i dont think that will help very much i dont think i would register that it is getting more could air so im kinda stumpped on this one

Honda ECU's use a fuzzy logic type system... resetting the ECU does nothing but make it forget about recorded trouble codes that may have come up... I.E. the check engine light doesn't always means something is wrong, it just means something was wrong at some point and it's saving the code for diagnostics until it's cleared.
But the fuel system and mixture is always being adjusted and re-adjusted whenever the car is running in order to run as the car sees to be most efficiant.
If you are running rich, I would check the primary o2 sensor out... extra cold air coming into the engine isn't going to make you run rich.. even if the ecu dumps more fuel in the mix, it's just to even out with the more dense air coming into the engine..... now on the other hand, if you are not running rich, you're just getting crappy milage, it's probably because more fuel is in the mix, so don't worry about it until summer rolls around again.

I personally don't like CAI... unless you're doing a lot of racing or like running your engine in the upper RPM bands (like 5,000k+) they're really not making any more difference than a normal intake tube.... and your chances of sucking up water are a lot less with a normal short ram intake tube.... even with a bypass valve, the bypass valve only works to choke the engine and kill it before it sucks in water IF the intake tube is submerged... but it doesn't stop any smaller moisture that may get on/through the filter.

im not running rich just getting shitty city mph like 17 but on longer drives its fine just trying to see if it can be fixed in anyway half tempted to just put the stock air box on with no resonator for the winter

fyi, they do oxidate fuel in the winter which gives you worse gas mileage
