I am undecided about which CAI I should buy. I am looking between two right now to fit my 05 ram 1500 4.7. I am looking at the K&N 57 series FIPK and the True Flow XDI. The XDI seems like it would flow more air than the K&N, but I don't know. I guess what I am looking for is who has experience with either of these two intakes and would you recommend it?

 

I dropped in a S&B rechargeable filter. Cost me $35 shipped. i just can't justify spending $250+ on any CAI. it doesn't do enough for me to justify that kind of expense for the power ouput. Get a few elbow's for $15 if you wanna remove the Hemi hat. I think that's maybe good for 2-3rwhp topps.
I decided to buy a Predator inplace of a CAI. Ofcourse it was only $30 more than the Volant set-up I liked.

 

kn 57 series. i have it and its awesome

 

What makes it so awesome? Just sorta curious? is it because it makes a diff sound? is that worth the added expense?
For that money you could go HID, bedliner, tonneau cover, floor mats, foglights, running boards...etc..

 

I voted other for any of the many aem/mopar knockoffs then pick your filter. You can get them for between $70-350.

 

ok well i like the sound yes but i gained 2mpgs so thats worth it for me and it was only 240. oh and i have all those things already minus the hids(which im getting soon) and the tonneau cover(dont want)

 

all of your alternatives are appearance only, and hes asking about intake performance opinions here.

I say K&N, but get a used one, dont pay brand new prices cause the used ones are just as good i.m.o.

That one only fits a hemi and I have a 4.7. Believe me I wish I had a 5.7, but I got a really good deal on this 4.7 and so I am just going to live with it. It has a good bit of power, alot more compared to my 96 chevy blazer. lol

I have always liked the K&N, but the True Flow extra heavy duty intake has a larger opening and I believe will flow more air. Whatever I get it will be flowing through new headers, Free flowing cats, and a Magnaflow 5x8 muffler that is a 14'' body. The FM50 I have sounds great, but its too restrictive and I think that Magnaflow will sound awesome with that set up!

 

The BFI should fit, you just might need a different coupler on the end. If you gonna drop 275 or more on it the BFI is best from what I have heard. Plus you could use it as an excuse to get a bigger TB (don't know if they make em for 4.7's) or a fastman ported one at the very least.
