Quantum Pro Dry S Oval Tapered Gray Air Filter (21-90103) by aFe. Quantum Pro DRY S air filter by aFe Power is specifically designed for the Quantum Series cold air intake systems and feature an injection molded base and top for lighter weight and rigidity. The newly designed base includes a built-in, 3-angle velocity stack for smooth, even airflow. The Quantum Pro DRY S filter is a 360-degree radial flow air filter with oil-free, 3-layer progressively finer porosity synthetic media for optimum flow, filtration and convenience. Captive screws are included to eliminate lost hardware and to securely fasten to the Quantum Intake system housing.

Oil impregnated air filters offer great performance and extended service intervals, but when service is required they can be time consuming, waiting for the filter to dry after cleaning and then applying the oil. So if minutes are precious to you there's a performance air filter for you, the Pro DRY S. The Pro DRY S was developed specifically to provide increased airflow and excellent filtration efficiency, in a filter package that could be washed and put back into service in a minimal amount of time.

The Pro DRY S filter contains 2 layers of randomly porous synthetic fabric. This allows approximately twice the airflow when compared to a typical stock air filter. The increased airflow results in more horsepower and torque, better throttle response and more miles per gallon. But this improved airflow and performance hasn't been gained at the expense of engine protection. The Pro DRY S has an excellent 99.2% filtration efficiency rating.

The pleats in the Pro DRY S are evenly spaced for greater dust holding capacity and the tips are rounded for better airflow. They're also 30% deeper than comparable aftermarket air filters for longer service intervals and greater dust holding capacity. The sealing surface and supporting structure of the Pro DRY S are made from 100% polyurethane, to withstand extreme engine temperatures. Flat panel filters are constructed with 4 sides, not just 2, for added rigidity and seal support, and feature a progressive bump seal to ensure an airtight seal.

Under normal driving conditions the Pro DRY S won't need servicing for 25,000 to 30,000 miles. Since a typical OEM paper element should be replaced every 15,000 miles, the Pro DRY S will pay for itself before the first service is required. And when service is required, the Pro DRY S can simply be washed and dried and put back into service; no oiling is necessary. The synthetic filter media dries in far less time than cotton gauze so your downtime will be kept to a minimum. The Pro DRY S can be washed and reused repeatedly; you'll never have to buy another air filter, ever.

Direct factory replacement Pro DRY S air filters are backed by a limited lifetime warranty. Universal clamp on filters have a 2-year warranty while racing filters have a 1-year warranty.

Easy Install Onto Jeep JKU, No Switch Backlight or Mounting Holes, Great Customer Service
Color: 5in Cube LED Pod, Color: 5in Cube LED Pod
I installed the Auxbeam 5" 168W LED Cube Pods onto my Jeep JKU Anniversary Steel Bumper. It was an easy install with some YouTube videos to help me snake the cables into the cab. The unused holes in the steel bumper were the perfect size to fit the mounting bolts on the pod lights, and there was plenty of room to reach under the top edge of the bumper to install the nuts with some Loctite. To snake the provided cable through the firewall, I had to remove the installed socket. This was easy to do by simply recessing the retainer clip on each pin, taking a picture of the wired connector before releasing the wires so I knew how to reassemble, snaking the connectorless cable through the firewall into the cab where the pins were then reinserted and locked into the connector. I dressed the cable by zip tie to the existing wire harness at the top of the engine bay. In the cab, I pulled the side panel from the dash (driver's side) and made a small hole for the cable in the panel. After cleaning the dash with alcohol, the adhesive-backed switch seems to hold nicely in place. The lights were very bright and did a great job of illuminating the front and sides of the trail ahead of me. No backlight on the switch, which is a necessity, and I dont understand why that feature is not present. Also, there is no through hole to mount as the adhesive back won't stay attached, so the lack of a mounting hole is a big negative as well. 5 Month UPDATE: One of the lights got water inside. I noticed two screws that hold the glass cover were loose on the bottom of both sides. The other light also had the same loose screws but no water under the glass. I contacted Auxbeam, and they replaced the entire set in 2 days. Very awesome customer service.

Brightness and quality
Color: 4*2.5in Cube LED Pod
Got this for my 2024 Crosstrek. Got this one specifically due to its functionality that I wanted, quality for the price and it looks great especially DRL. I leave the Amber cover on most of the time. If you want the DRL to be on while the car is on, you can do that but it has to be rewired which I did. Love the brightness. I’ve been having this on my Crosstrek for a few months now and have no issues.

Bright lights
Color: 4*2.5in Cube LED Pod
Installed these on my Bronco as ditch lights. Very bright light and I like that you can have them be white or put the cover on them for and amber light look. Took about 30 minutes to install and wire to the upfitter switches. They shoot a wide angle covering your blind spots on dark roads. I got these to replace a three inch ditch light. They're made from heavy duty metal and stand up to the extreme weather. I like them so much that I purchased the seven inch lights and install them on the front bumper. For what they cost it was a price that I couldn't pass up. I highly recommend these lights.

Great lights
Color: 52Inch Lights +LED Pods+ Wiring Harness, Color: 52Inch Lights +LED Pods+ Wiring Harness
These lights are awesome. Ridiculously bright and cheap. I have nothing to compare them to but they're for being so inexpensive they are tremendously bright for being a first time installer. I cannot speak to their longevity and the moisture as I only put them on a week ago and went on trail. The whistling is definitely kind of a pain. I've tried the double sided tape people mention and it softened the whistle but when you get up to 70 mph it is obnoxiously loud I'll have to tweak it some more. If you're sensitive to loud squeezing sounds it definitely makes the ride a bit uncomfortable and I would look at other light installations instead of the 52 inch bar. If you can get past the squeeling noise or dampen the sound better than I did then you can't beat the functionality for the price
