3.5 HO K&N Cold Air Intake

I know there are probably a lot of threads about cold air intakes, but I was wondering what you guys thought of their worth. I have a 2002 Intrepid SXT 3.5 HO with 58,000 miles and a Mangaflow exhaust. Honestly, I always thought that cold air intakes were pointless on a gas motor, but I rode in my friends Cobalt that just had a K&N intake put on it, and it sounded much deeper and was quicker (the rest of the car is stock). So is it worth it? I assume that this is the correct one:

Thank you.

I have the K&N filter, there's a nice small difference with it. I wouldn't anticipate to see any MPG differences though. Another option, made by a member.

That's the one. Cheapest I've found is $230 on Amazon (no tax!), $220s on eBay, or $216 at advance auto (+ Tax) after a $50 coupon.

Anyone with experience on with the j-intake?

My friend was was getting better MPGs with his K&N.

Would you recommend your K&N?

I bought from J-intakes, he customs makes then to what color you want and it's a lot more high quality than the plastic K&N gives you.

Here it is installed. I netted about 1.5-2mpg more. It cost me $200 from him + shipping I believe.

I got a lightly used k&n for free. Otherwise I wouldn't dish out the money to buy it. I'd probably just go to autozone and buy a few Spectra pieces, a barbed fitting from the hardware, and a decent oiled filter and put it together myself. And a piece of sheet metal to make a "box". If I was really feeling cheap, PVC works pretty well too.

Honestly, they are more upkeep and have potential to allow more dust past. A paper filter restricts some because it has to to filter out smaller particals. I'm not sure if they still do, but fram used to make a washable dry filter that claimed to flow better and still filter like a paper one. Maybe they made/make one for our cars?

Just my opinion , buts thats way too much money unless your into lifting the hood
to show off your shinny intake. The Bling factor is about all your gaining. Any of these companies that claim HP increases are doing a quick snapshot on the dyno at 6500
rpms, something you'd never feel driven on the street.

If you want to make it sound throatier from under the hood , cut a 1/2" off the bottom of
the air box with a std. hand wood saw and run a premium paper air filter " not a fram ".

K+N is a respectable company , but cold air intakes for the street are a total
waste of money. Marketing at it's worst " for the consumer ".

I disagree. I had a 7-10% gain in mpg I went from 22mpg to 23.5-24mpg and I believe that is a great WASTE of money. An extra 30 miles on a tank is a huge difference.

I never bothered for the longest time getting a cold air intake kit, simply because I couldn't justify spending $200+ for a brand name kit. I was just going to buy an eBay kit and jury-rig it to fit. Something off an LX or other Dodge vehicle with the right bends and lengths to cut and modify to fit.

While on a recent yard run, I decided to pop the hood on a first generation Eagle Talon that I always walked by. Sure enough it has a nice enclosure with a brand new K&N filter. Yoink!

Modded a small bracket for the passenger side, and the driver side tab fit right on to the factory mount for the original air box. Removed the retarded complex air-intake sensor assembly and closed all the screw holes and sensor openings with some chrome bolts and plates. Looks sick! Now I just need to ditch the stupid crinkle-pipe.

Really Impressed with it, the engine sounds throaty like I mean really throaty, throttle response is really sharp, no clue about fuel mileage, haven't driven enough yet. I think it was well worth the effort.

If it looks cool then thats a thumbs up from me.

the factory IS a cold air intake. so calling the aftermarket that is kind of a misnomer. most provide less COLD AIR than the factory ones.

I re-did my intake essentially using the stock filter box (which by the way if you actually look at it. it scoops cool air from inside the Passenger fender.) The deeper sound you can get by removing the two resonators. I used 3 inch ABS piping and a rubber sewage coupler. cost about $50 all together.. then just got a square K &N to fit in the factory box.

Cheaper and does essentially the same as a $200 custom brand name.
