I installed the K&N 57-3050 on my 5.3 liter 2006 GMC Sierra 2WD Crew Cab. I do a lot of highway driving between GA, AL, and TN, and wanted to increase my MPG. Before I installed the K&N, I was getting around 20-20.5 MPG's highway driving at a constant speed of 70-75 MPH.

Since installing the K&N, I am now getting anywhere from 22-23 MPG's! Now this is also driving a speed of 71-75 MPH. I have noticed that by keeping my engine @ 1900 RPM or less, my gas millage dramatically improves with my Sierra.

Now don't get me wrong, but this filter can also cause more gas consumption if you have a heavy foot. If you like to accellerate quick and get up to highway speed fast, this filter will do that for ya. But the downside is that it will cause more gas consumption. Wide Open Throttle = More Air = More GAS!

Overall I am extremely pleaseed with the K&N 57-3050 AirFilter, and I would recommend it to anyone who does a lot of driving with there truck or SUV and who is looking to safe $ in highway fuel costs.

This was too easy.
I got a great price and the air intake kit works like a charm on my 06 Silverado.
I have already hauled a bed and trailer full of almost 2 cord of wood 150 miles and still got 13 mpg. I definitely get 2-4 more mpg with the filter.
No complaints, highly recommend this to anyone.

I read the instructions before starting. It took about 10 mins to remove the factory airbox. About another 15 to install the FPK. It all went together very smoothly. I do not hear any noise under the hood like the instructions said might be present. At idle and low RPM you really dont notice any difference in performance, but when passing and at higher speed you do notice it. Nice little boost in performance. The truck onboard computer is reporting about 3 tenths of a mile better. The truck doesnt hit the highway for long periods of time and I imagine in time the gas mile will get even better. And as a side note, it looks really nice when installed under the hood. If someone were thinking of ordering this and was not really sure, I would say "go for it".

Item exactly as described. Great price. Awesome sound.Slight increase in power. Fit perfectly in an 05 Suburban 5.3.

I have an 06 Sierra with the 5.3 liter also. Truck is a crew cab. The installation was easy and quick. The thing I noticed right away was the difference in power and response on acceleration. I had heard that the engine runs a bit louder, but that is only when you put your foot in it. I have heard some say that the transmission shifts smoother also, and I found the same to be true with mine.

I was expecting a little bit better gas mileage from what others have said. I also replaced my spark plugs with NGK iridiums and MSD spark plug wires. I have noticed an increase in gas mileage, but not the 2 MPGs listed earlier. I have only had this on for about 2-3 weeks, so maybe I need more observation time. I think right now I'm probably getting about 1/2 to 1 additional MPG with the cold air intake, spark plugs, and wires.

Aloha from Hawaii! Like many of you reading this review, I was hesitant about the ability for a bolt on product to increase power AND mileage. I had monitored mileage from the time I bought the truck (07 Silverado Classic Extended Cab with 5.3 motor) and noticed a definite increase in mileage! Although I don't have any dyno results to show for it, the motor pulls harder and longer. Overtaking slower traffic while going uphill is effortless! Just have to remember not to keep the go-pedal punched too long or the increased mileage will run away from you! All in all, an awesome product at a great price with long term benefits! I highly recommend it and hope this review helps!

Very easy to install on my 2005 Chevy Avalanche. It takes a few days of driving for the computer in your truck to adjust then it runs very smooth and adds a noticeable amount of power. There is however a bit more intake noise under certain acceleration situations. Overall I'm very happy with the results.

Fit great on my "05 Denali. Instructions are marginal, but easy enough for anyone with basic tool skills. Noisey at 2300 rpm, but made a performance improvement you can feel. Not sure about the mileage improvement yet, but the engine feels much freer, I'm sure mileage will increase. Well worth it at $225 for genuine K&N. Helped with towing.

Very nice product by K & N Filters!! Can immediately feel the increase in torq and hp..And it looks awesome..Thanks..Plus Amazons prices were cheaper then over 15 places i searched, including Ebay, which didnt even have it to begin with ....

With a simple 64 piece tool kit from craftsman. I had this installed in 30 min. Give a grrr sound when you step into the engine. Love it!
