This system includes the components featured in the Stage 3 setup Inch extended travel 2. 5 Series coilover shocks, an ICON tubular Delta Joint upper control arm kit, 2 Inch rear coil springs, and a tubular rear lower link arm kit but sees the addition of 2. 5 Aluminum Series Remote Reservoir

ICON's 2003-2009 Toyota 4Runner/2007-2009 FJ Cruiser Stage 4 suspension system provides a significant increase to the on and off-road performance of the vehicle. This system includes the components featured in the Stage 3 setup Inch extended travel 2.5 Series coilover shocks, an ICON tubular Delta Joint upper control arm kit, 2 Inch rear coil springs, and a tubular rear lower link arm kit - but sees the addition of 2.5 Aluminum Series Remote Reservoir rear shocks for balanced damping characteristics front to rear.

The remote reservoir design allows for increased shock oil volume and enhanced cooling so that the rear of the vehicle can work harder for longer durations without noticeable Inchfade Inch occurring. The 2.5 Aluminum Series Remote Reservoir rear shocks also feature ICON's InchBump Zone Inch technology which significantly increases damping ability in the last 2 Inch of compression travel, preventing harsh bottom-out sensation and giving the vehicle a much more controlled ride quality over varying terrain.

ICON's tubular steel lower links are much stronger than the OE units, feature a low maintenance multi-durometer bushing, and can be adjusted for optimum pinion angle. On top of it all, these links have been designed to provide correct roll steer geometry for the best possible handling on and off-road.

Features and Benefits:
  • This system features upper control arms with ICON's patented Delta Joint. The Delta Joint is a heavy-duty high angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uniball. While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. The Delta Joint features a zinc plated housing providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal on metal construction and a greaseable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation. What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint.

Best air flow
Size: 9.6" x 11.1" x 2.2"
I have a 2022 ram 1500 four-door. The factory filter from the ram dealer is about $40 but it’s not reusable. That was the only one I found that had good airflow into the cabin. I tried several other brands but the airflow was reduced excessively. The ram filter was 15 mph, most of the other aftermarkets dropped the airflow to about 9 mph. I just installed a K&N reusable filter and the airflow is back up to 15 mph. Great job K&N!!

Fits Well and Reusable. I'm Happy.
Size: 9.6" x 11.1" x 2.2", Size: 9.6" x 11.1" x 2.2"
For less than the price of 2 disposable FRAM CV11671 cabin filters for my 2019 RAM 1500 and this will last forever. If it gets wet, like I've had happen with the paper throw-away filters due to stuff falling off trees in the spring and clogging cowl area water drains and backing up into filter ( yeah, that's a thing ) and can clean and dry this filter and reuse. Great directions came in the box along with a sticker to point out that this is a lifetime filter so someone doesn't throw it away. Do this yourself. Don't let some auto repair shop talk you into it. I was getting tires balanced recently and heard a quote they gave over the phone of $79 to do this. I don't know what kind of vehicle that was for but this ain't rocket science. Don't get ripped off. Now back to this filter. There is no arrow for air flow so I figure it flows well both ways and just put it in with the K and N logo right side up and facing out. It's not a straight in shot the way RAM positioned the opening for the cabin filter slot but was no big deal. Also realize this isn't a perfect square filter ...It's a rectangle so don't try to shove the fat end in and say it doesn't fit. I haven't noticed any air flow differences with the heating / ac system but some people say they do. I'm just happy I don't have to buy anymore disposable filters and can dry this if it gets wet. The cleaning and refresh spray kit is #99-6000 that comes with a 8oz and 12oz bottle and I'm trying to find that cheaper somewhere for when I do clean this thing.

Can’t go wrong with K&N
Size: 9.6" x 11.1" x 2.2"
So I recently took my pickup in to have some recall work done, half way through the process I got a call from the dealership stating I needed a new air filter and that a new one would cost nearly $60. I chuckled and told then to put the old one back in and I immediately came to Amazon and ordered this cabin filter. I’ve used K&N products in the past and have never been sorry, and that is the case with this lifetime filter. Upon installing this filter I noticed an IMMEDIATE difference in air flow into the cabin, it even smelled better. If this filter ever gets dirty Ira easy to clean and reinstall, paying for itself over time. Do yourself a favor and pick one of these up, you will not be sorry.

Easy replacement and noticeably fresher air
Size: 1-Pack
Installation was quick and simple, and it fit perfectly in my vehicle. I noticed an immediate improvement in the air quality inside the car. The activated carbon helps reduce odors and keeps the air feeling cleaner and fresher, especially during everyday driving. The filter feels well-made and durable, and it does a great job trapping dust and debris. It’s a simple upgrade that makes the driving experience much more comfortable. Overall, this is a great quality cabin air filter that delivers reliable performance and excellent value. Definitely recommend!
