YOUR STOCK AIR FILTER IS KILLING YOUR ENGINE

The photo below shows large particles and dirt beyond the filter element and headed towards the carb and engine. Below is the tube, after the air has been filtered, going from the air filter to the engine.

UNI-FILTER IS THE BEST HIGH-FLOW AIR FILTER AVAILABLE

Our High-Flow Uni Filter Intake Kit. Original air boxes on GY6 150's usually aren't very good at filtering and leak an unacceptable amount of dust and debris leading to premature engine failure. This kit eliminates the stock air box altogether, mounting directly to the carburetor. This filter setup is hydrophobic, meaning that it repels water and is perfect for riding in even down pouring rain.

It comes fully assembled and bolts on. Filter is to be oiled before using. The two filter elements are washable, reusable, and can be used over and over. Comes with filter, connector assembly to attach to carb and oil.

Note: When oiling use the UNI oil provided and NOT K&N or motor oil or some other oil. They will NOT work. UNI oil is a tacky formula specifically designed for the large pores of the UNI filter. Use Genuine UNI oil or the filter will NOT be effective! When dirty wash with soap and warm water and re-oil filter.

INSTALLATION TIPS--PLEASE READ BEFORE CALLING:

When installing the filter allow the hoses to hang. There is positive air flow from the hoses and nothing will be sucked into your carb or engine.

The coupler is designed to fit really tight. You may need to heat up the gray coupler with a blow dryer or heat gun in order to install onto the carb. We made it tight in order to prevent dust from getting into your carb and engine. .

Stock Filter Passing Dirt

Below shows the dirt air comes in though the center hole and dirt should be trapped inside of the inner diameter of the filter. But as as you can see there is dirt every where in the air box where there should be no dirt.

Kit Includes:

One uni filter
One can of Uni spray oil
One intake adapter

This kit comes with a can of Uni oil spray. We prefer the spray can over the bottle of Uni oil. The spray is faster, easier, less work and less messy. With the bottle the next morning after oiling your filter you will have a puddle of oil beneath your filter.
