Hey guys what are your thoughts on K&N filters with the 99 and newer trucks? Some people say the oil can damage the throttle body?

I love mine. I'm runnin the FIPK which replaces the whole air intake system. I haven't had any problems with mine or it damaging the throttle body or any other components. I'm sure a few guys on here will agree with me.

I've used one for a while with no problems. Just go easy on the oil when cleaning it. Too much and the MAF gets gummed up and will cause problems. GM has a bulletin about it.

Had my FIPK for about 3 years now and it needs to be cleaned...they have to right amount of oil on them when new, it's when you clean and oil them that you can get into trouble.

Does anyone know where we might be able to get that bulletin? I would be interested in reading it. Or, does it basically say what has been already posted. Thanks Guys!

3 years?!?!?!?!:screwy: I clean and re-oil mine every 6 months.

I have the AEM Brute force on mine and love it. Many Pluses. I got 2 more MPG, More throttle response, more noise when you get on it and it cleans up the engine bay making it easier to get to things on that side of the engine.

Only complaint I have about mine is that the last time I oiled i did the following procedure.
1) Remove from truck
2) Clean with cleaner provided and rinse with water.
3) Let Air Dry for 3 hours in warm garage.
4) Oil and let it sit overnight off of my vehicle on my bench sitting on the intake part of it.
5) Reinstall.

Now, That was pretty much per the directions I had. Everyday after that for about a week the damn thing leaked out the oil that I put on the filter. To hell with the oil.. I don't want that yucky mess on the inside of my fender well again. I think I'll switch to AEM's DRYFLOW next year or the year after.

I was actually thinking of getting one of those on my K&N intake. The only real drawback to cleaning and re-oiling the filter is that it disables the vehicle overnight.

Thats why I dont like them, Because I dont want to take the time to clean it and oil it, I would be afraid I would put too much oil on it too. I have bought the filter alone in my past 3 vehicles, and Im too lazy to clean it and then I just end up trading the vehicle in.

It's not THAT bad, considering you only need to do it twice a year.

I think you guys are just re-oiling with too much oil. If it's dripping off the filter itself, there's a sign right there. I've cleaned mine at least 10 times and each time I follow the same precedure. Spray, clean, wash (with distilled water), air dry, re-oil. I let it sit about an hour after I oil it and it's dry.

why not just save your money and leave the factory unit in, why expose your self to these problems? It seems like 2/3 of the mods have some type of negative change that nobody anticipated.

At least with the dryflow you just have to wash it and your done. If you absolutely had to you can wash it without the Dryflow wash cleaner.

That's why you do your homework on the mods before you install them. You gain information about them, how they work, how good they work, and if it's worth it. Besides, stock is for suckers. :iceslolan

I did the MAC intake last week and love it.

The MAC looks nice.. However you will loose HP with that metal tube leading into your throttle body.. That metal tube will heat the air up as it passes.
Looks nice in the enigne bay, but not practical for true HP.

I can't imagine it will heat it up enough to make that much of a difference. Do you have any data behind this?

That's pretty nice. Probably my only complaint with the K&N FIPK is that it looks too stock. People all the time ask me if the engine came with that.

It's ok, though, I like mods, but I like mods to look like they're supposed to be that way when I'm done.

Just to refresh everyone's memory to what the K&N FIPK looks like, and to see my once spotless engine bay (sniff sniff :( ) here:

Probably no studies related to this, but pop your hood and grab it after you've benn driving for an hour or two one day.

Don't tell him to do that. He'll get skin all over his intake tube. BTW that engine bay is nice!! Mine never looks like that :(

Same here :) I am just happy it runs! :)

I'm 45 years old, not 16. No way I would grab the tube! :lol:

TMI Too Much Info :)

Hey guys,

I've just been considering getting a new air intake for my '02 2500HD with the 6.0 in it. I figured I'd look on here to see what everyone said about it. I'm glad to see this thread started already.

My biggest concern is that I'd wind up loosing anymore mpg's. I always read that making it breath easier helps the mileage, but I don't understand why the manufacturer wouldn't do that themselves then as a selling point. And then I've talked to people who said it hurt their mileage. More power seems like it means more fuel. I'm already just getting 12 mpg with slightly oversized tires and it down to 8 when I tow my boat. Of course I'd like a little more power, but not at the expense of any more mileage if I can help it.

I saw one of you said it got an extra couple miles per gallon which is what I hoped to hear, but all this oiling the filter maintainence has me hesitating. Are there any other intake systems out there that don't require the oiling maintainence?

Thanks,

Chris

Those all look cool!! I really do like mine, though it looks more like stock, it did give extra power (and noise). Coupled with the True Flow foam air filter, I really like my setup.

I don't understand it, either, but the manufacturer does plenty of things theat restrict both power and MPG. My power and MPG both increased when I got my computer retuned. I got an extra +2 MPG. Also things like freer flowing intakes and exhausts would help power tremendously, yet auto makers just don't do thathttp://i8.photobucket.com/albums/a5/BlenderWizard/tard.gifhttp://i8.photobucket.com/albums/a5/BlenderWizard/tard.gifhttp://i8.photobucket.com/albums/a5/BlenderWizard/tard.gif

FYI, I decided to check this today. It was barely warm in 55 degree weather.

Go easy on the oil and its no problem.
Get the one with the plastic intake tube as the metal tubes retain heat and will give less of a power increase, K&N say that themselves.

The manufacturer doesn't do the mods that do allow better mpg because of the "noise" or so I've heard and/or read. The air rushing into the open element filter of the K&N or any other brand is noticeably louder than stock, which might distract the buyer. Probably why they don't put performance catback systems on the vehicles as well. Instead they put a muffler half the size of the vehicle so it'll be nice and quiet.

Exactly: We have to remember that the trucks are being sold to the masses, and not just Yahoos like ourselves who want MORE, MORE, MORE!!! Anyway, there is a purpose for those funny looking, resonator polyps on the stock intake tube.

Although the Chevy dealer I drive by everyday has more than half of the silverado fleet on the lot customized in some way. Either lifted with oversized tires or dropped with 20's + billet grilles on both. It might be that I didn't notice that type of thing 5 or 6 years ago, but I don't remember seeing that many customized vehicles on a dealer's lot then.
