Outerwear Pre-Filter, 14 Round, 6 Tall, Purple

OVERVIEW

In the high-stakes world of air-cooled performance, dirt and silt are the ultimate engine killers. Whether you are tearing through the dunes at Glamis or navigating the dusty trails of Baja, your engine''s longevity depends entirely on the quality of the air it breathes. This genuine Outerwears Pre-Filter is the first line of defense for your high-performance air cleaner. Specifically designed to fit 14-inch round by 6-inch tall filter elements, this purple pre-filter utilizes a proprietary polyester mesh with uniform micron openings. This advanced material acts as a primary barrier, catching up to 90% of the heavy debris and fine dust before it ever reaches your expensive primary filter. By stopping the "big stuff" and the fine silt early, you ensure that your carburetorbe it a Weber, Dellorto, or Holleyreceives a steady stream of clean air without the restriction associated with a clogged main element.

Beyond its impressive filtration capabilities, this Outerwears pre-filter is engineered for the harshest environments known to man. The mesh is UV resistant, meaning it won''t become brittle or fade under the relentless desert sun, and it features an optional hydrophobic water-repellent treatment. This is crucial for off-roaders who encounter damp conditions or mud; the water beads right off rather than soaking into the filter and choking the engine. Using this pre-filter significantly extends the service intervals of your main air filter, saving you time in the garage and money on replacement parts. At Appletree Automotive, we only stock components that meet our rigorous standards for durability, and this purple 14x6 pre-filter is the gold standard for sand rails, Baja bugs, and custom air-cooled builds that demand both style and uncompromising protection.

PRO TIPS

1. The Proper Way to Clean

Never use harsh degreasers or high-pressure air to clean your Outerwears pre-filter. To maintain the integrity of the micron openings and the hydrophobic coating, simply wash it in a bucket of warm water mixed with a mild dish soap. Agitate it gently by hand, rinse thoroughly with low-pressure water, and let it air dry completely before re-installing. Using a dryer or compressed air can stretch the mesh and ruin the filtration consistency.

2. Ensure a Snug Seal

When installing the pre-filter over your 14x6 element, ensure that the elastic or drawstring (depending on the specific revision) is tucked securely under the base and over the top plate of the air cleaner. If there is a gap between the pre-filter and the filter housing, dust will find its way in through the path of least resistance, rendering the pre-filter ineffective. A tight fit is the difference between a clean intake and a top-end rebuild.

3. Watch for Static in the Dunes

In extremely dry, sandy environments, static electricity can cause fine silt to "cling" to the outside of the pre-filter. Periodically during your ride, give the pre-filter a quick, gentle tap with your hand to knock off the accumulated "dust cake." This simple action restores maximum airflow instantly and prevents the primary filter from having to work harder than necessary. This is a trick used by professional desert racers to maintain peak horsepower throughout a long heat.
