JLT Air Filter Pre-Filter for 5×7-inch filters in Red by S&B

5 Star Tuning is excited to offer our customers the best pre-filters on the market!

This pre-filter specifically fits JLT’s 5 x 7-inch air filters. JLT Performance pre-filters are the perfect way to add style and protection to your JLT cold air Intake system!

Made just for us by Outerwears.

Pre-filters from Outerwears are made to increase the effectiveness of any exposed or performance air filter. A proprietary polyester mesh with uniform micron openings and a hydrophobic, water-repellent treatment is used in the construction of the pre-filter. The mesh can withstand up to 450 degrees of heat, is resistant to UV rays, breaks easily in freezing weather, and filters particulates down to .005 inches.

The threads can be impacted or shifted, but they can return to their original position because the material is elastic and resistant to punctures. In order to reduce potential failure points in the material, the manufacturing process uses reinforced industrial-grade thread to fill needle holes and strengthen the seam.

To strengthen the top’s durability, the top seam uses specialized thread and cording (on larger pieces with tops). Pre-filters are made to keep harmful debris that clogs air filters away and reduce maximum airflow and power. Additionally, the Pre-filter prolongs the time between servicing intervals, which lowers expenses and improves customer convenience.


An excellent way to keep water from puddles and big rainstorms out of the engine is to use the Outerwears pre-filter. The purpose of an outerwear pre-filter is to keep water out of an air intake system by making it repellent. Please be aware that while our pre-filters have been shown to be incredibly successful at keeping water out, they are not waterproof. Your intake can pass or hold water when submerged.

  • Outerwears pre-filters are an excellent solution to prevent water from entering into the engine
  • Outerwears pre-filters are designed to repel water against heavy rainstorms and road puddles

How long will the water repellency last?

Water repellency will last 6–12 months, depending on driving conditions and cleaning frequency. A quick test, however, can determine if it is time to replace your pre-filter. Just spray the pre-filter with an ordinary, clean spray bottle filled with water. Your water repellency is still active if water beads off the pre-filter. If you notice water entering the pre-filter, it is time to replace it.

Can I spray the pre-filter with water-repellent spray?

No. The water-repellency feature of Outerwear’s pre-filters is an intricate hydrophobic water-repellent process. It is not applied with a spray. This procedure is intended to prevent water ingestion while maintaining maximum airflow. Any aftermarket water repellency solution would reduce airflow, resulting in decreased fuel efficiency and horsepower. Water repellency is a factory process that cannot be replicated by spraying an aftermarket water repellency solution on it.

Will the Outerwears water-repellent pre-filter restrict airflow more than the non-water-repellent pre-filters?

A hydrophobic water-repellent process is used to create our water-repellent pre-filters. Because this hydrophobic water-repellent process is not sprayed on, there is no air loss. Water-repellent pre-filters from Outerwear have no negative airflow loss when compared to non-water-repellent pre-filters.
