FIPK GEN2 K&N Intake.

SandShots · November 29, 2006

got a K&N intake kit for my truck today and putting it in tomorrow.

what gains or losses can I expect. More HP and less gas mileage?

i own a 05 1500 HD with the 6.0L w/4.10 gears 4x4

it doesnt seem much offroad. but once a month i tow my toys to

the sanddunes wich is what i bought it for.

any thoughts or experiences please share. thanks.

It makes a cool noise

HawkeyeOC · November 29, 2006

I bought a K&N on one of my past trucks specifically because it went off road a lot. It's way better than a paper filter for that purpose and it saved me a ton of money not buying paper filters all the time.

I never noticed a HUGE benefit beyond that though. Maybe a tiny bit more low end hp from a dead stop, no mileage pluses or minuses...plus that cool sound!

Opinions will probably be all over the place on these. Some swear by them, others think they are worthless.

More noise

Same power

MAF sensor fault/SES light (if you oil it too much)

I had one in the last truck.

- Improved the throttle response

- Seemed to have a bit more power near the top end (helped with towing)

- Cool sound

- No change in MPG

I've used K&N's for years and never had a problem with a dirty MAF and the SES light coming on. My guess is it was one bozo who installed a K&N which was dripping with oil or maybe thought they could oil it with the engine running and this "problem" spread through the grape-vine.

On the new truck I decided to give the AirAid Jr a try because I heard the stock airbox is not really restrictive:

- Cools sound

- Maybe a tad improvement in throttle response, but then this truck never seemed to have much of a lag

- Don't really have to push it when towing so I don't know about the top end

- No change in MPG

I ordered one, it made me lose the lowend pulling power. It gave me alot higher power band, which I did not like, I liked it lower where it was usable. I have a 2003 Suburban with the 5.3 engine. I tow a boat and it did ok with towing, but normal driving I lost about 2 mpg in the city. It made a loud annoying wine on the HWY that was just a nuisance, so I sent it back and put my Stock K+N Replacement back in the stock air box and it works much better.

I would say Send it back and spend your money on the Wait4meTune. You will be impressed with this, this is what I did and that is the best $158 I ever spent. I wish someone would have told me this before I ordered the K+N CAI, and just went this way first, but luckily Summit Racing took it back no problems. But for $275 compared to the Tune for 158, this is a no brainer if you know what it does.

Hope this helps you.

LOL... I agree. Had and Airaid on my 1/2 ton and couldn't stand the noise. If your looking for a noticeable seat of the pants performance increase spend your money on a customer PCM tune. (Westers, Nelson, Wait4Me). I love my Wait4Me and it only cost $150.

I've got the newer 77 series on mine, and to be completly honest, can't really notice much of a difference. A little more throttle response from a stop, but as far as noise goes, I can't really hear it over the exhaust! However, if I open the hood at idle, I can hear the thing sucking in the air, but thats it. So, my advise would be to get a louder exhaust if you don't like the noise of the intake. Also, the more air in, more air out theory also applies here. If you are dumping 5000 CFM of air into the engine, but it can only expell 2500 CFM, the lesser of the volumes takes precedence. I think with an intake, and a free-er flowing header system or complete exhaust set-up, you may notice some small gains. Basically, you won't be blowing anyone's doors off with just an intake.

My dad just took his off of his 97 Silvy because it was causing some serious problems. It's back to stock and no problems.

you can expect it to be sucking hot air in from the engine compartment instead of cool dense air like the factor setup or a good aftermarket closed system. had an fipk on my tahoe and sold it after having it for a week for a volant.

Schmids5.3l · November 30, 2006

How is the Volant? Im pretty set on getting the one & the ram air kit.

On subject. I just have the K&N stock replacement filter. P.O. put it in. Just dont clean the d**n thing near the driveway or anything you wouldn't want stained. I can only hear it when Im in park and I tap the gas.

Valsport · December 1, 2006

the volant was good for what is was, when i had that truck it was the cutting edge of what was available (late 90's). fact is oiled filter elements have seen thier day, pain in the ass to maintain and f up maf's.

i am now running an outlaw power intake on the truck in my sig with thier dry filter element. they will ship you both if you want them. my advice to you if your looking for an intake for your 5.3l is consider NO OTHER INTAKES outside of the outlaw power system or the S&B system.

Sandshot, I would also watch those silicone levels in your oil. You can do so with regular oil annalysis. K & N and other oiled gauze filters will for sure let in more dirt. The question is how much is too much. For me, any additional dirt entering my engine is too much. This is why I selected the TrueFlow Intake and filter.

Valsport, I will respectivley disagree that the 2 CAIs are the only options to consider. I will not be critical of these units but I would encourage anyone to take a look at the TrueFlow unit. Here is why:

Retains the factory air box (true cold air system)

Uses an oiled foam filter & the oil uses a Tactifier so it will not contamintate your MAF Sensor

Very High Quality with excellent fit

Reall nice looking under the hood

Nice and quiet. Only slightly more "intake music" under load

Not sayig it is the best for everyone, but for me, it did exactly what I wanted it to do.

I have been conducting a test with my AEM cai and the stock system using my scan gauge intake air temp reading.What I found out so far is the AEM brings in cooler air on freeway 3-5 degrees over out side temp.Stock is 7-10 over.

City driving the stock box is 10-12 over and AEM is 20 over out side temp.

Cut a 3" hole in bottom of stock box and that gave me about 2 degrees cooler.

Saw no differance in performance with eather of them.

stock is on now.

Other systems might run cooler? Just my 2 cents.

Bish · December 1, 2006

I would agree you should watch silicates if using a K&N type. I had one on my Tahoe for about 150K and I had oil analysis done every oil change. My silicates were 1ppm higher than the paper filter and IMO well under control. I now have 183K on my truck and Blackstone says it is wearing like it has 30K. I think it has more to do with oiling. I think there is a fine line between under oiling and over oiling. Under oiling and you let silicates pass. Over oiling and you coat the MAF.

Having said all that, I removed it and went back to the stock air box and a drop in K&N. While I believe it had better throttle response with the K&N, I grew tired of the added noise after 65 years.
