S&B Filters JLT Air Filter Pre-Filter, Fits 4x6 & 4.5x6 Inch Filters, Blue
$29.95

If you’re looking to step up your air intake game, you might want to check out this pre-filter designed specifically for our 4.5 x 6 inch and 4 x 6 inch air filters. This isn’t just some add-on; it’s a solid piece that adds both style and protection to your JLT cold air intake system.

Custom made for us by Outerwears, this pre-filter is built to enhance the efficiency of any performance or exposed air filter. The construction features a proprietary polyester mesh with uniform micron openings, and it's treated with a hydrophobic water-repellent process. What does that mean for you? Well, it means this mesh is UV resistant and can filter out debris as small as .005 inches. Plus, it’s shatterproof in freezing temperatures and can handle heat up to 450 degrees. Talk about tough!

The material is puncture-resistant, which is a must if you're hitting rough terrain. The elasticity of the threads means they can bounce back if they get impacted or shifted. And let’s not forget about the manufacturing quality—welded seams and reinforced industrial-grade thread help reduce potential failure points, so you can trust this pre-filter to hold up.

What’s really cool is how this pre-filter works to keep your air filters clean. It deflects debris that can clog your filters, which means you get to enjoy peak airflow and horsepower for longer. And who doesn’t want to extend the time between servicing intervals? Less hassle and more time on the road.

Water Repellent Feature

Now, if you’ve ever had to deal with water getting into your engine after a heavy rain or hitting a puddle, you’ll appreciate the water-repellent feature of this pre-filter. It’s designed to keep water at bay, which is a game-changer for those of us who love to push our vehicles to the limit. Just keep in mind, while it’s great at repelling water, it’s not completely waterproof. If you submerge it, water can still make its way through.

  • This pre-filter is a solid solution to prevent water from entering your engine.
  • It’s built to handle heavy rainstorms and road puddles without breaking a sweat.

How Long Does It Last?

Wondering how long the water repellency lasts? Well, it really depends on how you drive and how often you clean the filter. Generally, we recommend swapping out the pre-filter every 6-12 months. A quick test you can do is spray it with a clean water bottle. If the water beads up and rolls off, you’re still good. If it seeps through, it’s time for a new one.

Retreating the Pre-Filter

Thinking about using a water repellent spray to refresh it? Don’t bother. The water repellency feature is a factory process that can’t be replicated with a spray. If you try to add an aftermarket solution, you might end up restricting airflow, which could hurt your horsepower and fuel efficiency.

  • The water repellency feature is factory-made and can’t be duplicated.
  • Our water-repellent pre-filters won’t restrict airflow compared to non-water-repellent options.

So, if you’re looking for a pre-filter that offers real protection and performance without compromising on airflow, this Outerwears pre-filter is worth considering. Trust me, it’s a smart investment for anyone serious about their ride.
