.. for increased performance? I'm debating right now since want the extra air flow but not the dirt. Is this filter really worth it?

 

If you worried about increased particulates reaching the engine; the answer is no.
If you want more free flowing intake; the answer is yes.

 

You will have no problems with the K&N. If you like to drive in dust storms, I would not reccomend a K&N. Every day Vette weather; you will be fine.

 

I did it and you should too!

 

Whats an oil filter for??? I have been using K&N air filters on all my cars for over 20 years. Never ever any problems. Even after 150000 miles. I guess I might be concerned in a sand storm or something. Never been in one.

 

I have put K&N in every car I have owned since 1998, corvette or not. You will feel the car breathe better. You don't have to clean it for 50K in miles. Very much worth the money.

 

If all you would plan to do is replace the paper filter with a panel K&N filter, I wouldn't bother. The performance increase will be negligible, and there is no question that the paper filter provides better filtration. If you simply must change, I would go for a Donaldson panel filter (assuming you can still get them) or Green filter over a K&N, as IMHO they have a better filter media. Good luck with your decision.

The K&N is okay. Nothing special really. I have the K&N on my coupe due to the fact it has a carb exempt number and I gotta have that in Cali. Felt an improvement in power after install, but I expected to feel something due to the restriction on the stock air box. It all comes down to what you want to do with your car. The K&N is a good filter and will keep dirt out of your engine, but keep it clean. They say you can go 50,000 miles before you have to clean it, but I would clean it around every 5000 to 10000 miles depending on how dusty your driving environment is.

 

Beg to differ there. I allways notice an Increase in mileage and power.
Be using them since 1976. Paper is crap, Compared to the K&N.
Love people like this, there are always slower.
Paper Does have better filtration who cares they have no air flow.

 

You know, it is smartazz comments like this that discourage people from attempting to help others or even make an attempt to exchange information in venues such as this. OK hotshot, I'll look forward to your dyno results or some other quantifiable testing of this filter under the parameters I mentioned - beg YOUR pardon if I don't accept your SOTP meter.

 

You know I really think the answer to this question depends on the time of the month...
It seems that at least once a week the question is asked on one of these Forums... and depending on the day, you will get..."it's the best thing in the world" and everyone will agree. A week later "it's no good and will ruin your engine" and an equal number will agree...

Based on the data I've seen, I think this is a pretty good answer...

Running them in my 03 Dodge Ram hemi, 2005 Mustang GT, and my baby 01 A4 Mag red coupe. They do make a difference if you are doing the intake mods.

 

Well if you haven't made up your mind y now I would think that your best source of info would be from those who use them. Obviously they are going to know from experience. As others have mentioned, it will help a small amount without doing something to the cover. Either go with the free method or even the 2001 type. I'm sorry if I missed where you mentioned what year your car was. But from experience you will not regret it. I do also agree with the person who said to try a Green Filter or a Donaldson. I know that the Green uses a woven cotton element and therefore is less prone to breaking down under cleaning. They are extremely well made too. A friend of mine had a 97 and said his car felt like it was missing that ooomph when getting on it. Well we cut his filter intake and put in a Green Filter and he said he noticed it big time. SO in other words, you can feel it SOTP. I have heard that with the stock box that some have even had the accordion bridge collapse from a suction effect. Anyway, I would venture to say that your best source of info on this topic is from guys who have tried them.

 

Been running a Cone K&N on the GN for the past 45k miles, it's positioned about 5" above the street, and have driven in some very bad sand storms (West side Albuquerque, looks like the sahara when the wind is over 25mph) Haven't had the engine apart, but with 152k miles on it and still running 11's, I don't think it's hurt too bad from running a K&N and "letting all that dirt into the intake". Every car I have or will ever have, will end up having a K&N or at least a similiar type of filter (airhog, etc...)

 

His expert answer wasn't helping a thing. The K&N will get you a car.
Least a tenth,K&N Panel filtervs.Paper panel filter. K&N design (cloth screen) (different manufactues since K&N lost the patent) is used .
On every friggn' Indy car, Drag racer. Nobody in racing uses paper.
Why, Good filtering and still has great flow.
Want your dyno sheets on the difference Go to the K&N web site.
Sorry got a little sour, but what he was saying was wrong.

 

I am going to have to line up behind wamara on this one -

The poster asked if there was a performance increase that was worthwhile from just installing a K&N filter - and he also said that he did not want additional dirt as compared to a factory filter (he did not state it that clearly, but that is the jist).

If you think you are feeling an improvement from just installing a different panel filter in the stock airbox, you are just experienceing placebo effect.

Your profile shows that you had your car dyno tuned (i.e. computer edit was done to lean it from factory settings) while at the same time you installed a halltech system on your 02.

You should feel that increase.

I would put money on the fact that your "one car" would not materialize in the 1/4 from only a k&n filter in the stock airbox, and even if it did (and it won't), it is rediculous to think someones butt is that sensitive as to discern that amount of an increase.

Oh, and racers generally don't give a hoot about more dirt in the engine when eaking out more high rpm ponies is the end-all of racing.

BTW - wamara is an expert in many areas. He is a long time contributor to this forum , owns two C5's, and has more credibility (and tact) than you have yet to display to us.

You will end with more silica in the oil period. I race mine and don't care I use a K&N. I have seen this on the turbodieselregistry.com for the past 4 years with prove. It filters better when dirty. Why, because the dirt filters some of the holes. Longevity stay with paper few HP K&N. Do an oil analysis and report back with both.

 

Wamara is 100% correct-

A K&N filter alone will not give you a noticable increase period. and I too have used them for many, many years in all kinds of vehicles. If it is performance you seek- then go with an an after market intake such as Vararam\Blackwing or what I have a Haltech Stinger. If you are concerned with dirt or dust in the engine- then you may want to stick with stock...a K&N will bring more air in then paper- but a BIG open air filter and large airbridge will make that increase noticeable. Just ask the vararam guys about the SOTP and 1/4 mile times they net...using a K&N in my daily driver and the intake TB is clean as a whistle...

 

Guys, question: if I were to replace the stock panel filter with a K&N replacement, is it the same "pop open and switch" process as is used with a paper filter, or do I need to apply a "seal" to the lower portion of the airbox, as is implied by the instructions on K&N's website?
