K&N 63 Series Aircharger Kit (63-3087)The K&N 63 3087 AirCharger air intake system replaces the restrictive factory air filter and air intake housing in some Chevrolet Silverado 2500 HD 3500 HD and GMC Sierra 2500 HD 3500 HD models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration

The K&N 63-3087 AirCharger air intake system replaces the restrictive factory air filter and air intake housing in some Chevrolet Silverado 2500 HD / 3500 HD and GMC Sierra 2500 HD / 3500 HD models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The 63-3087 air intake comes with a black metal topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through an aerodynamically engineered intake tube into the engine's turbo inlet for a guaranteed power gain. The tube accommodates the factory mass air sensor, humidity sensor and filter minder (where equipped). The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, ratchet set and some wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Features:

  • Guaranteed to increase horsepower and improve acceleration
  • Custom designed and engineered for each application
  • Works with OEM computer system
  • Includes the world's best air filter, the K&N filter
  • Easy to install
  • Up to 100,000 miles between servicing
  • Million Mile limited warranty

There are two problems with your OEM air induction system that cause restriction and reduce airflow. First, airflow is restricted by the size of the filter in the factory airbox. Even a replacement performance air filter can only flow so much when its size is limited. Second, the air path from the filter to the throttle body can be restricted by the OEM intake tube. Together, these two areas of restriction combine to reduce airflow and rob horsepower from your engine.

Luckily, these problems are easily solved with a K&N 63 Series Aircharger Intake Kit. K&N starts by replacing the restrictive airbox and small air filter with the largest size conical shaped high flow K&N air filter that will fit in the engine compartment. The great increase in filter area over stock vastly improves airflow and the capacity to capture and hold dirt. Then K&N replaces the OEM intake tube with a precision designed, rotationally molded tube made from interlaced high density Polyethylene. This tube eliminates air path restrictions to the engine and reduces air intake temperature when compared to similar metal tubes. Intake air temperature is further reduced by a heat shield that isolates the filter from the engine compartment. The reduction in air intake temperatures results in a cooler, denser air intake charge and even more horsepower. All components are mounted and connected with high quality materials such as steel, aluminum, silicon or reinforced nylon, to ensure long life.

K&N uses a dynamometer to design its air intake kits to make the most horsepower possible. But their power figures aren't based on just one vehicle, but rather an average of runs by a number of vehicles. This means repeatable numbers and horsepower claims you can count on.

DO NOT PURCHASE
This face wash has not only irritated my face, but also my hands. My skin has had horrible. Allergic reactions to everything by this company when I’ve never been allergic to anything in my entire life. I’ve gone out to four dermatologist and none of them can figure out what’s going on, but all of them have identified that these products are the issue however they do not list all of the chemicals in English so it’s not something that can be identified easily.

Too harsh on my sensitive skin for daily use
This cleanser contains a variety of emollient and moisturizing oils, but it also contains potassium hydroxide, which indicates saponification, a process that turns oil into soap. While it has the appearance of being an oily liquid, it foams up nicely on wet skin to create a luxurious lather. It has a fresh, clean soapy scent. I can't quite place it, but it reminds me of something from a long time ago. It is a little powdery and perhaps more of a mature scent, but I really like how clean it smells. Unfortunately, I find it to be quite harsh on my skin, which is likely a result of the saponification of the oils. One day of use here and there will be fine for me, but daily use makes my skin quite dry. In fact, it makes my skin squeaky clean, which is not necessarily a good thing. It is a shame because the scent is so nice, and I love the oil-to-foamy-lather formulation. Another issue is that the dropper on the bottle arrived clogged. It is really puzzling because the cleanser seems to be completely liquid. I ran the dropper under very warm water for quite some time in an attempt to clear the clog, but I was unsuccessful. So, in using the product, I've just been pouring it into my hand. This could also be contributing to my issues with dryness, as no matter how hard I try to dispense a small amount, pouring the cleanser out of the bottle inevitably results in my using more than would have been dispensed from a dropper.
