What exactly is a K&N Drop in ? sorry not to familiar with a lot of car accessories yet.

 

It's a replacement filter element, just like the stock one only "oiled" gauze instead of paper.
You would not notice any differece at all using it, and they cost around $50 ea.

 

But, with the K&N they have a warranty for the life of the car, so in the long run it may be cheaper.

As far as the CAI, from what I've heard, I'll make a hissing sound with my mouth as I hit the gas and spend the $200-$300 on something worth it.

 

Agreed.
If you don't mind the look of the "stock-box," your money would be better spent elsewhere. This coming from someone that has a CAI installed.

 

Also coming from someone who has a CAI installed an AEM one, you can save your money and just buy a drop in, what you feel is going to be the same as a 200 intake, i wish i could find my flow chart readings

 

Cheaper? Unless one plans on driving a quarter of a million miles in the car, it is unlikely to be cheaper than using OEM style filters, especially so due to the fact that the K&N doesn't filter any where near as well and may lead to extra engine maintenance and/or expensive repairs.

 

K&N filters flow better than oem, thats a fact, as for it causing problems that is untrue, again i wish i had all the readings from my power and performance class, it would show what works and whats doesnt, for anything all the cars that had a K&N intake or drop in our shop it flowed better than stock and at the least gave 1ftlbs of tq

 

Well even after reading all the talk and stuff. I am definitely going to buy a CAI for the looks and just because i want it. I think we all agree it does look pretty nice when you pop the hood

 

nah, i got tired of it quick, rather have a sri with a cf box, oh btw buy one of those universal "socks" that go over the filter that or get a shield, i believe Rich has one on his

 

While a K&N might flow better, I seriously doubt it will make a measureable difference in power (and zero difference in fuel economy) when installed on virtually any modern engine. The flip side is the extra dirt K&N style filters allow through and the potential for extra maintenance of the induction system (or even the engine) itself after prolonged use. I'll stand by my statment; K&N filters will most likely never pay for themselves.
