S&B Filters JLT Air Filter Pre-Filter, 5x9 & 6x9 Inch, Blue, Water Repellent Mesh
$29.95

If you’re running a JLT cold air intake system, you might want to check out this prefilter. It’s designed to fit our 5 x 9 inch and 6 x 9 inch air filters, and trust me, it’s more than just a pretty face. Made by Outerwears, this prefilter adds a layer of protection and style that you won’t want to miss.

What sets this prefilter apart is its construction. It’s crafted from a unique polyester mesh that’s got uniform micron openings, which means it filters out debris down to a mere .005 inch. That’s pretty impressive when you think about the kind of gunk that can clog up your air filter and mess with your horsepower. Plus, it’s treated with a hydrophobic water-repellent process, so it’s ready to take on rainstorms and puddles without a hitch. Just keep in mind, while it repels water like a champ, it’s not completely waterproof—so don’t go submerging it!

Durability is key here. The prefilter is built to withstand tough conditions. It’s shatter-proof in freezing temps and can handle heat up to 450 degrees. The material is puncture-resistant, and it has a bit of elasticity, so if it gets knocked around, it’ll bounce back to its original shape. The seams are welded for extra strength, and they use reinforced industrial-grade thread to minimize potential failure points. You can trust that this thing is built to last.

One of the best parts? It helps extend the time between servicing your air filter. Less time spent cleaning means more time enjoying the ride. You’ll save some cash on maintenance too. Generally, you’ll want to check the prefilter every 6 to 12 months. A quick test is all it takes: spray it with water, and if it beads up, you’re good to go. If it soaks in, it’s time to replace it.

Now, about that water repellency—don’t even think about trying to retreat it with some aftermarket spray. The hydrophobic process used in manufacturing is specifically designed to prevent water ingestion while ensuring maximum airflow. If you were to spray something on it, you’d risk choking off airflow and, in turn, your horsepower and fuel efficiency. So, keep it as is; it’s engineered just right.

In short, this Outerwears prefilter is a solid investment for anyone serious about their JLT performance setup. It’s tough, effective, and it’ll help keep your engine breathing easy while looking good doing it.
