K&N Dissappointment
- Thread starter GT300
- Start date
I put K&N filter into My son's Motorcycle but I also rejetted the carbs and cut extra holes into the air filters box...It ran like a scalded Ape! Just dropping in a new filter wont do much you have to add more gas (rejetting) and make sure there is no other restrictions to Air flow (extra holes in the air box. everything effects everything else. Then if you do all that and dont open up the exhaust...you are just wasting your time!!!! if it breathes big it has to exhaust big...these are basic fundamentals of every gas engine.

ouch. I didn't realize this forum was full of $&!*heads. The question was if a K&N filter makes a difference. What more could you ask for? I dropped one in a heavily modified engine (did some tuning) and couldn't get it to run better at the track. The car is a very consistant car, and That IS a real test. As a matter of fact, it's as good a dyno test because different dynos from different manufacturers will give the same car different HP and torq numbers. This is a real world test.
I'm picking up my 05 GT today, and I'll be sure not to take advice from the uneducated people who frequent this forum making assumptions based on claims of a manufacturer.
I guess Wsmatau is going to tell me that I should have ordered a red mustang because the red paint makes them lighter and more aerodynamic. I'm glad I wasted your time, and I hope you read this again so I wasted more of it.

P.S. I've found that people driving Mustangs of any year typically drive like morons, I guess they act like them too when they are out of their cars... I hope I don't turn into one. I'll have to sell it and go back to owning GM cars that don't consistantly break down.

well I guess the appropriate response would be a joke about how in a Chevy you'd at least be driving rather than pushing or towing...
retiredgeneral are you upset about something ? american muscle cars are suppose to be fun and are a special breed. I think what you did with your K&N filter was a real contribution to mankind and the world of Chevy Novas
but this is a Mustang forum. Can you be positive in here I am a new member to this site but some of these people that come here in here to stir the sh&*
make for humorous reading and it shows the spite they have for a car. The other character excon is that guy high and mighty on the M3 or what. The most powerful car in the galaxy you'd think by now the M3 had a jet engine and wings. Come on men I know the net has to have a site for your cars. Who knows some of the other mustang owners in here might like your posts
it does make for good laughs.

Ok..."and now for something entirely different"...back to the real subject of this thread....for those of you interested, here is a web site showing a test of air flows for different air filters.
http://home.usadatanet.net/~jbplock/ISO5011/SPICER.htm
Hopefully no one will get a bee in their bonnet over this. Let the fun begin!!!!
Advice is free, take it for what it's worth.....opinions are like as####s, everyone has one....and on and on and on........
Many of us here do have knowledge that is worth listening to, and there are some who don't know a lot, but want to learn......I know quite a bit about cars...but I am open to new views and seek professional help when needed.....the doctors say I'm much better now!

Welcome aboard Rick! Jokes are always welcome...bashing isn't
WSD....those results are pretty interesting. They seem biased towards AC Delco just from the way results were reported, but I haven't seen anything that refutes these findings. I don't recognize a few of the brands (WIX, No Brand, Balwin) are these filters re-branded before they hit the market (Motorcraft, FoMoCo, Fram, etc.)? The point of the study was definitely true. When I changed my oil last week I had to go to a local shop that didn't have Purolater (what I normally use) so I picked up the K&N only to find out that it actually filters 2% LESS efficiently and costs 3X as much.
The tests show the AC Delco paper filter totally destroys the K&N as far as actual air cleaning and max accumulation capacity. The K&N flows the most air and only has roughly a 1/3rd of the accumulation capacity.
Seems pretty common sense,
Flows more air = less restrictive filter = less actual filtering.
The interesting thing is the AC delco actually flows MORE air than the K&N after 200 grams of accumulation and does so almost till it's max capacity.

I wonder if you would have noticed the same increase if you just, simply, replaced your old dirty filter with a regular stock new one?
jt14894 said:
As an alternative, I would guess that K&N tells you to wait, to allow enough time for your original filter to get old, dirty, and clogged first.
The WIX and Balwin are national brands, but not everyone carries them. Many of the filters out there are manufactured by the same companies, just re-named for the company that contracted with them. Many of the Auto Companies contract out to these same manufactures with certain Specification the want or they pick and choose from their current manufacturing runs. One company I know of "Fleet Guard" manufactures for others as well as their own lines.
I have used K&Ns over the years and have found they do a pretty good job for the driving conditions I find in my area. I would be a little more interested in how they introduced the grit, dirt & dust to the filters. Unless you drive through a sand or dirt storm regularly or race in the desert... you will probably get just as good results with a good quality paper filter. Many of the newer filters are a blended material (not totally paper) to increase filtering of particulate. Also, many of the aftermarket filters offer a foam pre-filter for extreme dust conditions. This is going to be an interesting research project as to who is best or right for us to use. Curious who makes the Steeda CAI filter I have installed on my GT??????

I remember reading somewhere that K&N recommends that you do not to install it on a brand new vehicle because, I believe, it does not have a lot of miles yet and that the engine/CPU has not yet fully conditioned itself to the stock filter. If you put in a K&N as soon as you get your new car then the engine will condition the K&N as a stock filter and therefor no gain at all.
With my latest car (2003 Nissan 350Z), I waited until it had about 10,000 miles on it and then I added the K&N. The factory Nissan specs stated 20 MPG City and 26 MPG Hwy. Before the K&N, it was averaging about 21 MPG City/Hwy, but after I added the K&N the MPG improved approximately 1.5 to 2 MPG to average about 23 MPG City/Hwy. The car now has 26,000+ miles and it still gets excellent MPG. On my last road trip, the car averaged 27.5 MPG, on one fillup, while crusing between 75 - 80 MPH.
With my new Mustang, I'll be doing the same thing.
Another thing to note is that if you don't break in your car properly the car will perform poorly and the K&N isn't going to help.
Also, I've seen and ridden with people who constantly pump the gas pedal while cruising on the highway or intersate. That type of driving completely wastes gas.
Whenever someone like that comes around me on the highway, I see them slowdown and speed up slowdown and speed up so what I have to do is speed up and get the hell away from them. AAAH!! Its so annoying. I HATE THAT!
I just want to scream at them and tell them to control their foot or use their Cruise Control.
Conditioned itself to the stock filter? Are you for real? If the computer still has to adjust for the filter then why not change it right away so it adjusts for the K&N? ANd I guess you cant put synthetic oil in the motor until after it breaks in. These are just rumors and are NOT TRUE. Why do some cars come from the factory with Mobile 1 synthetic?
ANSWER: Motors DO NOT have to be broken in anymore. The rings are already seated BEFORE they leave the factory.
Take your car from the dealership and drive straight to a dyno and do some pulls. It WILL NOT hurt the motor.

Well never having to replace it is nice. Another unncessary cost out the window. So losing less than 3 HP? Ok. Since I don't race my car, means very little to me.
Update on my dilemma
WoW, I appreciate the feedback just wanted to let everyone know my car is back to normal. I didn't do anything at all it just kind of worked itself out. However, this was after I installed the SLP axleback. Talking about "LOUD AND PROUD" the sound and power is incredible!!! All is well with my pony I'm new at all this MOD StuFF. My previous car was a 2000 V6 Mustang which I never got around to adding some mods. Anyways, I look forward to reading the forums I must admit I've learned plenty from all your experiences, knowledge, and opinions too!!

Well I see there is no winning with you. But let me say this. The time is not worth it for me to fool around and clean then reoil the K&N just to lose power. Id rather buy the stock filter and not lose power.
I guess everyone likes to spend money to lose power.
And how is it unnecessary cost? I can buy 3 stockers 1 K&N. The 3 stockers will last me longer than I will have the car. But even if the stockers will cost more, who cares? If your that hard up for money then get another job.
Bottom line, stock is better than K&N.
Stop making excuses and admit your wrong.
