Wondering about installing a K&N Filter on my Hemi. Is the replacement filter OK, or is an FIPK or similar CAI better?
Would like to here from those with them.

 

If you use the search function, you'll find countless threads on this.

Basically, in my opinion, the CAI and FIPK are the most beneficial for horsepower and fuel mileage increases. Of course, both work best with a free flow exhaust system.

Drop-ins are just a replacement filter and yield little if any results in the HP department.

Yeah, lots of opinions on this one. The big thing for me; paper Fram filters are surprisingly expensive-- pushing $20 and should be replace every 15k so I picked up a barely used K&N off eBay for $20 and won't even look at it until 50k. I already have the oil to re oil it at that time, as I have K&N's in all my vehicles. TIP: don't pay $ for the K&N oil, there are other off brands made for reoiling motorcycle filters that is basically the same stuff.

 

I have a drop in K&N no difference in driving with it.... go with the CAI

 

........And if you happen to drive througha moderately deep puddle with enough speed you can kiss your motor good-bye as it sucks up water throught your very pourous "high performance" drop-in K&N filter. The paper filter in the stock air box is an essential component protecting your motor from water ingestion. It is designed for that task. The air intake of the Ram truck is connected to the wheel well and will ramjet water right into your air box under the right conditions. The K&N filter will not protect your motor, the stock filter will.

 

Wheel well... Humm.

 

If there were "Tool Police", they'd take your's away immediately. First of all, the stock airbox is designed to elevate the filter to prevent water entery. Secondly, it has a "snorkle" that allows air to enter the box, so the water would not only have to be as deep as the box, but be present at the snorkle for a prolonged period of time, to enter the airbox long enough to be sucked into the filter, at the filter's level.

Which brings me to THIRDLY, if you think that water can only be sucked up into a K&N air filter and not a stock filter, or that your stock filter has some magical, protective powers to prevent water from passing through it while applying throttle, I have a list of things to offer you at a discounted price:

1.) Nevada Ocean-front property.
2.) A virgin,hooker.
3.) An Honest used car salesman.


Get a grip..........

 

lol, agreed. water in my opinion would be less likely to pass through a k&n filter than a paper filter. oiled filters such as a k&n filter make water passage dificult while your paper filter is readily permiable to the water( it will soak it up quickly). if you have a CAI with an oiled filter the next timeit rains i challenge you to check your filter for water saturation. if gooddocs theory is correct itll be soaked. Ill tell you first hand that i have never had an issue with water saturating my filter. even after massive amounts of rain or carwashing.
