The K&N AirCharger 63-9034 air intake system replaces 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. This allows your vehicle's 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 63-9034 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. This allows cooler, denser air to be directed through a custom molded intake tube into the engine's throttle body for a guaranteed power gain. The oversized 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 requiring only a screwdriver, pliers, socket set, and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Works great,not for heavy oxidation
This stuff works great, but it's best to grab (Awesome) spray, to use as a first step. The yellow oxidation melts away on contact, then rinse your headlights thoroughly with water and micro rag dry. Then use the wipes that come in the box to clean the headlights thoroughly again, rinse with water. Once thoroughly rinsed and dried, apply the UV clear coat with simple left to right or right to left strokes. Let it dry and enjoy.

Good for the effort and price.
This will _NOT_ make your lights look brand new! It will make them clear again. Or mostly clear if your lights are super bad. I had one old light and one new light on my car when I bought it. It drove me crazy walking by my car. I used this exactly per instructions other than I rubbed the crap out of my light. I got great results! Not perfect though. I got two clear headlights now. That is what I wanted. The finish is a little rough. This is to be EXPECTED since you are not using buffing compound. Use gloves. The finish looks like a light is a few years old now instead of 15 years old. It will not be can not make your light look new. Get the expensive kit if you want new look. My lights look close enough to not catch the eye. I am satisfied.

Not bad at all!
These headlight cleaner wipes worked far better than I thought they would. I have used many a headlight cleaner and restorer, but this kit was the easiest to use with very good results. No need for power tools or even different sanding disks. Just two different types of wipes, super easy. We will see how long the lights stay clear for, but if I had to do it once a year it would be worth it! Four stars because the lights came out clear, but not crystal clear, but to be fair that may just be the condition of my headlights. Try this least expensive, easy fix first. It many very well be just what you need.
