I'm thinking about getting a K&N filter, and have a few questions.

- Is there a noticeable difference in accleration?
- How much is the HP/TQ gain, if any?
- How long does the filter last?
- Does it keep residue out as well as a paper filter?
- What kind of maintenance needs to be done for this filter?
- If I choose to get a lid/intake, can I still use the filter?
- What size does the LS1 take?
- Is it worth the money?

Thanks.

 

Here you go:

- No.
- Hardly any. Some drag racers say, though, that paper filter flows better, so go figure...
- K&N guarantees it for million miles, so I guess it'll last a long time. As long as you take care of it.
- Maybe even better?
- I think K&N recommends cleaning and oiling it every 40-50K miles. I do it every 10K, though...
- Yes.
- Don't remember the size or part number off the top of my head, but do some searches with some of the vendors on this sie and I'm sure you'll find it.
- Depends. To me it was since I got a used one very cheap and was able to transfer it from my Firebird directly to the Z.

Glad to be of help!

- Is there a noticeable difference in accleration?
Nope
- How much is the HP/TQ gain, if any?
Probably 0
- How long does the filter last?
It's got a million mile warranty
- Does it keep residue out as well as a paper filter?
It seems like it, so IMO yes
- What kind of maintenance needs to be done for this filter?
Just buy the cleaning kit and clean it whenever it gets alittle too dirty, I don't know how long that would be w/o the FRA. I clean mine about every 5k miles or so
- If I choose to get a lid/intake, can I still use the filter?
Yep
- What size does the LS1 take?
Not sure about the size but I believe the part number is 33-2118
- Is it worth the money?
That's up to you, I got 20% off my lid/filter so I just decided to go ahead and get one

 

I'm with the guys above. I've got it. I don't claim to make more power because of it. I never "felt" a difference. I don't "believe" there's a difference ('til I see a dyno paper proving otherwise). It does fit with a different lid. It's good because it'll last the life of the car if you clean it periodically. Worth it?? Long term "yes", short term "probably not".

 

It sounds like the K&N isn't worth it.

Thanks for the info. guys.

 

The advantage of a K&N filter is the fact that you dont have to run to the store and buy a replacement everytime yours gets dirty. All you have to do is clean and oil it and your all set. There is no HP increase, unless your replacing a dirty filter with a clean K&N filter. Even then its minimal and your only going to see 2-3 hp, which wont register on the butt dyno.

 

Not exactly.

You will save the price of the filter in just a couple of years, depending on the amount of miles you drive and whether you think air filter is important or not.

Sometimes you can see pretty wild-looking filters since many people don't give it a second thought...

i dont know about a noticable hp gain on the v8's but when i put it on my 3.8l v6 i could tell a difference. ive been told it will make a 5-10 hp gain (id like to see dyno results thogh) but with acceleration, i could tell a slight difference. but overall i think its a good buy, seeing that you will never need to replace it.

 

I agree with what was said above and saw you mention about possibly getting a lid. Most websites offer a deal where you can get a lid and filter for a little bit cheaper then it would be to buy them seperately, of course they did this after I put filters and lids on both the Camaros.

 

I dont feel that aftermarket filters are worth the $..

Sure you can get one for about $30-$50 but I would rather run a new filter more often.

Just my personal preference.. Even though you only lose 3 rwhp with an aftermarket filter (proven on my reveiws) I think that those 3 are what I would rather keep..

As for lids.. the 8rwhp I found you can get with them is not worth the loss in MPG.. I would only put it on at the track if I were to use mine.. I much rather prefer getting 27+mpg as opposed to 24 with a lid.
3 miles per gallon.. on a 16.8 gallon tank.. of which I normally use 14.2 is 42.6 miles lost.. Thats roughly 2 gallons.. per tank..
every 7 tanks full, thats 1 tank full of gas.. So to me, it makes more sense to stay stock.. at least for now..

I almost forgot.. the sound.. at first it wasnt as noticeable.. then I took the lid on a road trip.. AUGH! too much engine noise..

 

K&N doesnt fit properly with LIDS...im gettin rid of mine and gettin an AC delco.

 

I have to add that while it may be a "hassel" to run to the store to get an air filter (and where did you get the oil for an oil change?)...

I can change stock air filters faster than anyone on this planet can "recharge" a K&N filter.. How is that possible? The instructions state that the filter must DRY... that takes time..

The install of a new filter can be done in under 2 min.. doesnt seem unreasonable to me.. Plus I would rather run a new filter more often than run a "cleaned" filter...

 

Get a Holley not the K&N I just remembered the K&N makes you put on a gasket and the holley doesn't need one.

 

i see this all to often, people disputing over whether the k&n is better than paper filters. most people say that paper outflows the k&n but they are wrong, click here and here is a test of different filters on a tunercar. even though the k&n does outflow paper filters you most likely wont feel 4hp at best that you'll get over a new paper filter but me personally i like nowing that i have that meesly couple of hp.

 

I had the K&N and now have the Holley. Much better fit and no stupid gasket. It's wort it in the long run. No more buying new filters. Just cleanit and reinstall it!
