K&N air filter system... worth the money?

[IntenseCash]

I just bought the replacement filter for my 2002 FX4 Ranger. I really didnt notice a better response for it costing almost $60. Should I invest in the replacement air filter system that costs $260 retail? It claims to increase horsepower and get better gas mileage.

Your thoughts?
Thanks, Chuck

[KMR Stitch]

I was gonna get one for my 93 Ford Ranger XLT :-)

[fuzebox]

The horsepower increase is negligable, but you will get slightly better gas mileage.

If it's a cold-air system, you'll notice a bit more pull, especially on a cold night, but nothing that could really be described as a "performance increase"

[Steve]

$260 just for an air intake system and air filter? Got a link to it? I'd like to see the parts list of this kit.

Sounds pricey to me, but that is without seeing what you get.

K&N was always a good item in the past, though.

[Fu-Q]

i have the k&n cold air intake on my 2003 s10; i like it, but i havent had just the filter before, so i dont have anything other than stock to compare to

[newbreed]

I had the same truck. I got the K&N, but didn't notice an increase in HP until I added exhaust and a chip. I gained close to 80 horse. These trucks are really torque'y, so that's where you will notice the most increase. Mine, for example, before the upgrades, FELT slow off the start. Because the truck weighed as much as it di, it couldn't get out of it's own way. After the upgrade though, it fellt much more responsive in the low end, and their was a much more pronounced "burst" of horse-ies in the 1st two gears.

Good luck man, nice truck!

caution: the fine film of liquid used on K&N's will eventually coat the mass air flow sensor on Fords and youll be going to the dealer cause you will get a check engine light and the EECIV computer or OBD-II will not respond correctly to the current air-fule ratio it is receiving. And the dealer will hit you for paid labor instead of warranty work. My tip for the day

the only thing i have a k&n airfilter is on my bike. it made a little difference

K&N will add 3-5 horse tops. full out cold air systems are roughly 10 on a truck like that. Honestly, save your money for the repair bill, cause that thing is gonna break down every 20 minutes.
You want real power, go out, get nuts, but a supercharger or a turbo and make it work. At least this way youll notice something that truly demonstrates power more than "it feels peppy."

[ztik]

It really depends on how your stock system is setup if you get any improvments or not. If your stock system does not allow good air flow then it can make a pretty noticable improvement.

The K&N made for lexus sc400's/300's actualy take away hp. The stock system is setup with a cold intake snorkel already so you can't really get much better than that without a blower.

But... its a ford. so I assume it would help.

the oil on MAF is caused by over oiling your K&N. all you have to do to clean it is disassemble your intake and MAF sensor and spray 409 on a rag and gently wipe it

[Mr Pheer]

I put a K&N on a turbo RX7 along with a greddy exhaust, and it made so much boost that the computer would cut the fuel to the engine, so then i had to get a chip to alter the fuel flow... and yes it made a big difference

but without freeing up the exhaust flow, you wont really notice much difference with just the K&N cold air system... but free up the exhaust flow, and you will definately notice the improvement

[JDog]

$260 for a K&N system! I paid about $75 for my F-150 I had a few years back! But it's just the Filter. I noticed a difference in just the filter!

this is obviously a lie and/or you don't know jack shit about rx7's.

[Dirty D]

Got 4 K&N Air Filters on my Motorcycle....

Any vehicle will benefit from a K&N along with a more free flowing exhaust....

Check out the monster torque and hp during my burnout on http://www.netace.com/vmax

[greentea]

I got the full intake kit put on my expedition. It does give me a slight increase of horsepower.

Hey dipshit

The computer on a 10th Anniversary Turbo RX7 cuts the fuel flow when the boost reaches around 8.6 pounds

Dont ever call me a fuckin liar or tell me I dont know what I'm talking about.

LOLOL you said the intake and exhaust made so much boost

the upgraded intake and exhaust flow allowed the turbo to make more boost... dont you know anything?

K&N + Greddy exhaust = less resctive flow = more boost = greater than 8.6 pounds = computer cut fuel to rear rotor


fuckin idiots on GFY, gotta spell out everything to some people

That may have been what you meant, but it led me to believe otherwise due to the horrible way you described it.

[Basic_man]

It's only for the sound, not the performance!

[evilshaun]

First, I would invest in a new ride..

But I put one into my Denali, along with a chip and dual borlan exhaust kit and increased the HP noticeably, I would say 40-50 HP more

[rip raster]

I put a K&N cold air induction system in my bmw and it did increase power slightly, but the big difference came when I completed the package with a less restrictive exaust system. It will be going into the shop in the next couple of weeks for some cosmetic work and a supercharger, plus a few other engine modifications

I flip lowered preludes... so i dont even bother trying with the trucks i know they're dust.

did ya strike oil?

[DirtyDanza]

I put a K&N on everything I got... my truck my bikes... everything.... million mile warrnty plus the dirtier they are the better they work.... even if K&N's cost me bucu bucks I would still say yes... you will notice a difference always... plus you never have to buy another filter in your life.... just clean with water throw some oil back on let dry and your good to go.... I saw K&N plus castol syntec your set... I use nothing but castrol syntec in my truck and redline syn in my bikes.... best on the market... I bet you won't find a nascar not using K&N it will give you like 3-7 hp boost and guzzle more gass but your better off that way

[DirtyDanza]

and then get flowmaster on there dual chamber or you'll rattle your brains out... with like a 2 inch tail pipe remember the smaller the tailpipe the more backpressure you get which means more jump when you hit the throttle and it also means you slow down quicker with the engine.... which I use alot even in a automatic

now why would you put a smaller than stock exhaust on? thats constricts airflow, which would nullify the gains from the K&N

Funny, mine had over 100k miles when i traded it in. The only repair work it needed was BEFORE I did any work to it (<1800 miles on it).

The truck ran much better after the mods. Better economy, better throttle response, very noticable power increase.

Geuss sometimes it depends on the vehicle in question. Different vehicles, (but the same models) may exhibit different results.

smaller exaust = more backpressure which = more torque and better engine breaking... trust me... you know nascars only have 3 inch tailpipes... I am running 2.5 on my truck...

getting into a discussion on backpressure,baffling, harmonics and so on in regards to exhaust with gfy'ers is a waste of time and energy

[Stewie]

I have not invested in the full systems, but I have used K&N filters on a medium SUV and a sport coupe. While there is not a huge difference, both vehicles had a noticeable difference in acceleration power, especially from a stop.

[PostWhore]

You wont feel the hp gain. It is minimal. And installing cold ait intake without heatshield is stupid. You will suck hot air out of your engine bay and actually lose hp.
