Air Intake Kit from K&N

Excellent product with great instructions. Have felt a noticeable increase in power and responsiveness in my Dodge Charger R/T with 5.7L Hemi. Plus, I'll never need to replace the old air filter again. Be careful removing the air temperature sensor from the old hose as the body of the sensor can be brittle if it is too cold outside.

Fit, but didn't

This product fit my engine, but didn't fit the frame of my car. Only one of the two mounting points worked for me; which meant that it flopped around inside the engine compartment. I assume that it was designed for another LX platform (e.g. Challenger) that was sportier than my 300C. I didn't really mind returning it, after I read the LX Forum performance challenge tests that were financed/performed by a consortium of LX owners. In that test, it proved that you could obtain just as much performance from the original OEM air cleaner and air box as with any after market CAI system. The only bonus that a CAI provided was the loud growling noise of air being sucked into the throttle body.

Personally, I didn't like the growl as it let everyone else know when you were at wide open throttle and thus had no more oomph to give. It was also loud and startling enough to alert every cop on a coffee break within 3 blocks to chase after you for "going for it." It also totally drowned out the throaty rumble of my $1400 Corsa exhaust system.

As for the claimed horsepower gain, my controlled 0-60 performance test showed no improvement. I don't believe that the manufacturer outright lied, but instead uses fuzzy logic. Here's what I mean: No one would ever pay for a new air cleaner and then decide the very next day, "I'm going to buy a K&N CAI today." No, probably only after their OEM air cleaner was downright dirty and clogged and needed replacement; would they then justify the expense of a CAI. Thus, when you compare the efficiency of the new CAI vs. the old dirty, clogged air cleaner - yes, performance gains can be acheived.

K&N air intake for Dodge Magnum

I have had the K&N cold air intake kit installed in my 2007 Dodge Magnum R/T for about a month now. I can definitly tell a difference in the sound of the hemi when I accelerate. The gas mileage is not that much difference but hey its a hemi!

Rating :

I bit expensive but oh man does the Hemi roar!

It was easy to install (relatively) and looks nice under the hood. I don't think there has been much improvement in mileage or HP but the HEMI sure sounds nice.

Editorial Review :

The K&N 63 Series Air Charger Intake Kits virtually eliminate restriction between the air filter and the engine by replacing the air filter and the entire air path to the engine. These intakes use only non-metallic rotationally molded tubes that can reduce intake air temperature and decrease intake sound over a metal tube. K&N air intake kits virtually eliminate restriction between the air filter and the engine by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into the engine, which translates into power. The K&N 63 Series Intake Kits are not legal for street use in California.

Killer Air Intake

I had a K&N Air Intake in my 2002 Nissan Xterra and I loved it so I ran out and got this one for my 2006 Xterra. I have noticed more power. They say up to 14HP which seems kind of high. It does sound great though. My gas mileage probably has went down because I set on the gas so much to hear the sound.

K&N Air Intake

Easy and fun to Install. It took about three hours. I haven't performed any serious performance tests yet, but at least it makes the engine sound cooler.

Editorial Review :

Built for performance and show utilizing the highest quality components, the K&N 77 Series High-Flow Performance Kit is a free-flowing mandrel-bent aluminum tube induction system designed for Trucks and Sport Utility Vehicles. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow, allowing your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable and are relatively easy to install using tools commonly available.

Easy Install, Item works as described!!!

Installed this product in about two hours. I spent quite a bit of time on one of the hose clamps that I broke; otherwise, it would have been quicker. My truck sounds great. I'm handy with tools, but I'm not a pro.

I am still on my first tank full of gas so I don't feel I have had enough time to give you a credible mileage improvement estimate, but if the company is right, I should get at least 4 mpg more than I do now ... and boy do I need the improvement!

I wish it would have been clearly stated that this product is not street legal in California though. I'm told I may have to reinstall the original air box when I go to have my truck smogged.

Toyota Tacoma 4.0L V6 2009

Although the motor layout seems to be the same for the 2005-09 models of the 4.0L V6, the papers in the box clearly states that it is made for the 2005 model.

I still got it to fit, but when it came down to bolting up the engine cover, the screws didnt match up, had to custom it here and there to fit, but once done, oh man!!!!! The power is insane!!! Its a shame this one isnt street/smog/C.A.R.B. legal.

Bought this with next day shipping as i am a PRIME Member on amazon.com, i ordered it late monday evenning, they processe the order Tuesday and shipped, and i received the product on wednesday, for a little over $200!

You cant go wrong with the price there as ordering from K&N, this product is over $320
Same as the auto parts dealer, they sell it over $300

Definitely improves sounds!

Easy enough to install. Directions were a little generic and not to precise, but I did it myself! Everything is included except the tools to do the job. Took me about 2 1/2 hours to complete. It definitely improves the sounds coming from the engine compartment. Gets louder under 3/4 and full throttle acceleration. My F 150, 5.4 liter truck feels more powerful and has more "grunt" than before. Next on my list is a Superchips power tuner.
Just so everyone understands what I expect to achieve, I am looking for more power and torque so that pulling my 16 foot work trailer is less cumbersome and the shifting of the tranny is less annoying.

Amazing Product.

Great product, at a great price (For what it does). Noticed a huge difference in sound and performance. As for mpg increase, I havn't tested it out yet. It gave my truck (08' Ford F150 5.4L V8) a mean sound coupled with with my Flowmaster 40 series muffler cat-back system on a single 3 inch pipe. I will be recieving My Jet Performance chip in 2 days. We'll see how it all ties together.

Here's some advice on keeping the filter running solid. Clean that Mass Air Flow Sensor every 4-6 months with the proper cleaning spray. Can Be Found at any local parts store or on Amazon. Grab the quick dry solution.

As for Amazons shipping and customer support. Fast and Professional as always.

Enjoy the power.

Very pleased

Like other K&N intake systems I have purchased, this one was just as good as the others. Installation was straightforward. On my 5.4L '08 F150, I was pleasantly surprised at the RIDICULOUS amplification of engine sound at wide-open or mostly-open throttle. The in-cabin engine noise is really, really nice. The heat shield and plastic induction tube will undoubtedly help keep intake temperatures down.

great product

I installed this product on my 2008 f150 in about an hour. It bolted right on, and when i turned the truck on there was no check engine light or other light on and there hasn't been since then. My truck sounds great and have seen a little improvement in gas mileage, I would recommend this to a friend. Well worth the money.

Outstanding Change in Performance

I have a 2008 F-150 SuperCrew Cab truck and I was disappointed in its performance. I bought and installed a performance chip a couple months after I purchased the vehicle, and it somewhat helped performance but the engine still felt rather sluggish and it was definitely inefficient. In June 2010 I purchased and installed the K&N air filter system and WOW, what a difference!! It not only improved my gas mileage by 1 1/2 mpg (even with the Air Conditioner running), but it has that "let's get up and go" spirit I wanted out of my truck! I couldn't have imagined the difference in feel\performance of the truck, and I am ecstatic!! Trust me, you need to install a K&N air filter system in your vehicle. I figure it will pay for itself in about 20 months of normal driving (1,000 mile per month with gas at $2.70/gallon), plus you get the benefit of enhanced performance and increased mpg for as long as you own your vehicle. It is an absolute "no-brainer" decision to install one of these systems for yourself!! There are a lot of parts to the system, so I grabbed a baking tray and some painter's tape and sectioned it out to hold parts and labeled the sections so it correlated to the reference in the instructions. It proved to be a pretty easy install with this system as the parts were quickly identifiable. It still took me about three hours to get it installed, but hey, any determined person can get the job done and your efforts will be rewarded.

Editorial Review :

AEM’s patented Air Bypass Valve virtually eliminates the chance of hydro-lock in the event the filter of your AEM Cold Air induction system becomes submerged in water. On most systems, the valve installs along the upper portion of the inlet pipe and shuts down induction at the filter when it becomes submerged, rerouting air through its external diaphragm to keep water out and air flowing in. Check with your dealer or call AEM for more information on air bypass valve installation locations. The AEM Air Bypass Valve is C.A.R.B. exempt on AEM Cold Air induction systems only and is NOT for use on forced induction vehicles. Patent #6,394,128.

Customer Review :

It's pretty good...

Being that this is an AEM product I expected a lot. I've driven through rain with this valve and have had no problems, of course if there were to be problems I would no longer have an engine due to hydro-lock, which is why this valve is so important if you want to run a Cold Air system ALL of the time instead of switching to short ram when it rains. It really is meant for just AEM intakes which is something you should consider if you bought an intake off eBay. Anything is adaptable, but it won't fit as well as if you would have bought a straight up AEM pipe. Overall it's a great product and works quite well. I would have designed it a little better, but whatever. The pre-filter is right out in the open and gets cut up sometimes. For the price, it's quite good.
