Tahoe

i installed this unit on my 2004 Tahoe. It was a little harder to install than anticipated. Took 3-4 beers. Had to cut a good chunk out of my fan shroud. Looks sweet though and definitely gave me some good power.

Great Product at a Great price

Install took about an hour. Instructions were easy to follow. I can feel a little increase in power off the line, but more so when going from about 35 to hwy speeds. I think it will preform better after I install a new exhaust system to help get all the air a place to go.

Great throttle response, not better MPG

I have put a K&N Fuel Injection Performance Kit Gen2 Air Intake Kit on my Chevy Tahoe and Honda Civic. One thing that is immediately noticable is the greatly improved throttle response. When you press on the pedal, it jumps off. We have not really enjoyed a significant improvement in MPG. It may help a tad, but driving style and tire pressure I think our bigger influences on the MPG you get.
When excelerating heavy, you will have a significant increase in engine noise. We actually like it, but some may be annoyed. The best part is not having the guys who change your oil trying to sell you a $10 air filter for $30.

Cold air intake for Ford Expedition

Installation of the cold air intake on our 2009 Ford Expedition went pretty well and removing the factory intake left the engine compartment looking clean and well organized. The parts forming the box itself were hard to join tightly together, leaving a slight gap which is ultimately hidden by the filter and doesn't seem to affect performance. However, it would've been nice if the dimension were a little more precise to close the gap. This addition did a lot to wake up the 5.4L engine with some noticeable HP increase and appears to provide approx. 1-2 mpg gallon more as long as you travel at about 62 mph. My wife called me the first time she drove it and asked what I did to the truck to make it sound like a hot rod. The first time she put her foot in it she looked around to see if there was a performance car passing her.

K&N Intake for 2009 F-1504X4 Supercrew

I was getting between 17 and 19 MPG before installing the new intake system. Now I am getting between 18 and 20. The noise level is the same as before until you need the power with a load on the truck. I do see a big difference in gas millage, if I baby it, and will get up to 23 MPG when driving 70MPH on the level highway over 60 miles total back and forth. It was tough getting 21MPG when driving at 65MPH before the new intake was installed. My next step will be adding dual exhaust, which should give my truck it's best gas mileage.

WOW

I really like this. My mileage has increased by 3 mpg in town I don't know about highway I haven't had a chance to do a good road trip; Horsepower is up by 15. Noise is a little higher than with the old Lincoln intake it now gets peoples attention. I'm glad I got it!!!

GREAT!

This has helped me with gas mileage, arrived on time, and it was really easy to install. Recommend it

sound is awsome

I already had dual exhaust on my '07 f150 and it sounded great, I really didn't believe that there would be much improvement in the sound when I installed the k&n cold air intake, but I was suprisingly wron. It sounds awsome, like the truck is getting ready to chew someones head off. There is an increase in hp, I don't know how much because I have not put it on a dyno, but you can defenitely feel a difference. Installation was pretty easy with the step-by-step instructions. I would defenitely recommend this intake if you have a few bucks to spend on an upgrade.

Sounds great

This product was very easy to install took less than 1hr. The air intake plus my super chip work great together. next is the exhaust then i'm done for a while

Gas Mileage???

I've only put a few hundred miles on my '07 F150 since putting the air intake system on. There is a increase in response from my engine, but I have not seen an increase in fuel economy. I would recommend this product for added horsepower, but would not recommend it for the increase in fuel economy that is advertised.

Very Good Buy

I just had it arrive very quickly, also installed on my 2009 JK Jeep. I wasn't expecting to fly back in my seat with this intake but it did have a noticable throttle response and a new low end quickness. Very nice if your commute is in the city... passing power.
Took about 2 hours to install due to minor mistakes on my part the instructions are thorough but i think its easier installing by the picture.
All in all a very good buy for the Jk wrangler

Great upgrade

I liked the idea of improving air-flow to my engine (2010 Jeep JK), so bought this system based on K&N reputation. The directions were a little lacking, and I have more than an average knowledge of engines. One bolt stripped out and I had to use parts I had around the garage. The installation took me about 2 hours, from removal of the old system to installation of the new system. Is performance improved? Not indicated by the seat of my pants, but I do believe their performance graph. No additional noise was noticed from in under the hood. I would recommend a system like this for anyone, but it just doesn't have to be K&N. I would have hoped for more - but this is my first purchase of their product.

Rating :

Highly recommended

My 2008 Jeep JK Wrangler has noticeably better low-end response with this installed. Intake roar at WOT is pretty sweet as well. I don't know (yet) if this will improve my fuel economy, but it certainly hasn't negatively impacted it, which is fine with me.

I put all the parts together and figured out where each part goes; after that, it took about 45 mins to install. I had a heck of a time trying to get the front engine bolt off, but besides that, it was quite easy.

Easy Install, Good power Gain

My first impression when I test drove the Jeep Wrangler Unlimited was that it was quite gutless. Coming from a 325hp Chevy truck, this was going to be a big change. After doing some research, it seemed that a cold air intake was the best bang for the buck so to speak. UPS guy dropped it off at about 11:30, I unpacked everything and gave the instructions a quick once over. Looked easy so I decided to install over lunch hour. Simple as heck, probably took less than 1/2 hour to install. Took it out for a little test drive and power gain was instantly noticeable. Don't have acces to a dyno, but the good ole seat of the pants dyno worked just fine. I love the sound of a cold air intake too. Reminds me of the old days when we flipped the lid of the air cleaner on Mom's Buick. Highly recommend!
