Yes, I run mine all year. I usually clean the air filter once a year and reoil it. I have plowed through snow banks, slush, etc and never had a single problem with it. It gets real cold here at times also, was around 0 for awhile last winter as well. Car runs great in the winter with CAI. It feels stronger in the winter then it does in the summer. But you shouldn't have a problem with a cai in the winter unless you drive through some deep water....

 

Jinkies!
$65 at the auto store for a fluid change..
Oil, Filter, and transmition stuff... (comming upto a transmition flush and filter replacement)
Im hopin it wont rain this afternoon so I can get under the thing and do all the work I need to. Problem with florida is it rains a lot....

Thanks for the info guys and gals. Ill cleana nd oil my filter and move it behind where the fog light 'would' be.

 

Bypass Valve or not...i would say it's a good rule of thumb to not run a cai in the rain. I just ordered a brand new cai off ebay. But it's been raining a LOT here and we have another hurricaine coming so I think it's going to be a while till it sees my car.[:@]
