K&N cold air intake filter, pros? cons? should i put one in?

Hello, well ive already replaced the cat converter in my car with a header and i was told i should get a K&N cold air intake for my 2006 engine in my 2002 Nissan Altima 2.5L (replaces 2002 engine with 2006), and well i would love to hear any input from people who have already done this.....i read some things online and most are saying its a rip off due to water sucking and it being some kinda oil filter. I would love to hear some feedback, give me your honest and factful opinion.

Get one if you're looking for a bit more power plus a deep sound. As long as you have the fender liner mounted securely, you should be safe from hydrolock. Other cars have slits in their fender liners which puts their engine easily at risk if they have a cold air intake installed and run through a puddle. But you can always convert it to a warm air intake during the winter as a safety precaution.

I like my K&N. Did give it a deep sound. The filter isn't really low to the part where water can splash into easily.You'd have to be hauling ass through a puddle to get it wet

Well I can't speak about the cold air intake but I do have the K&N short ram for my 3.5 and I love it... It's not hard to maintain... Filter doesn't have to be cleaned and re-oiled very often at all... I'm willing to bet I could go up to 40 or 50k miles without cleaning and re-oiling... I decided to go with short ram because I'm here in Houston and we get heavy rain often in the summer... Great sound, slightly better throttle response... Overall worth the money for me...

The hydrolock debate, here we go again, lol. I've gone through my second winter with my CAI on without issue. I ran a while without the filter on (unknowingly) and still had no issues.

your not going to suck in any water if you put it in the right place, and hae all the fender liners and under panels still installed around it. another note don't soak the filter in a ton of oil, then you might get problems, moderation is key

^Qft... I thought about buying a CAI recently to replace my SRI, but I discovered soon after that my splash shield ripped almost completely off lol... So with heavy summer rains approaching, that thought has gone into the trash...

would it be worth dropping just a K&N Air filter in the stock air box? or should i save my $40-50 bucks?

OEM Replacement filter vs K&N Typhoon

If you plan on buying the CAI I would suggest not to spend your money on the OEM replacement. I have the K&N Typhoon and love it. I also have an OEM K&N replacement filter sitting in my garage collecting dust! Waste of $50! Here are the pros about the Typhoon; it can be made into the WAI for winter mode and the CAI for the rest of the time. It comes with a filter dry charger (filter condom) to keep the water out during wet times and it works pretty well. I noticed a difference in throttle response right away! It does have more power now. The cons... GAS! I use more gas! I don't know if it is because I am putting my foot into it more or it's just burning it quicker. The other is the price, but the price is common for a CAI.
Here are pics:

Short ram (WAI) Winter mode, for me at least.

Cold Air Intake

Take your baffle out for both because if you don't have fogs, air is forced up into the wheel well towards the filter in WAI mode. And when you don't have fogs, the filter sits right behind the opening where the light would be and acts like an intake port. Because of that NO FOGS FOR ME! The only thing you have to watch out for is if you take your car through a car wash with high pressure sprays, it might shoot into the fog light hole and hot your filter. It's a good mod.

there isn't a airbox housing for the filter? I know Volant, AEM and few other CAI have the black housing that box in the filter.

has anyone done a 2 degree timing advance?
