Dinan High Flow Drop-in Replacement Filters are a direct upgrade to your factory intake system and will instantly provide better flow to assist your engine in achieving maximum performance and efficiency! While factory paper filters function admirably, they can be restrictive to performance goals given the material used. They also require being replaced numerous times during the lifespan of the vehicle, which can add up to a substantial amount in maintenance costs. Limited performance and increased maintenance costs are never ideal but can be resolved effectively and economically in the case of filters. Dinan High Flow Drop-in Replacement Filters are constructed of 4 layers of cotton gauze that allow better flow and less pressure drop than the stock media. This equates to the engine not needing to work as hard to make the same, or more power. Additionally, the use of oiled cotton media means that the Dinan filters are washable/re-usable while still retaining excellent filtration and ensuring your engine runs clean for the duration. When upgrading to a complete Dinan intake system for best performance, is not available, possible, or within the budget, Dinan High Flow Drop-in Replacement Filters have you covered! General D401-0041 Filter Dimensions: 265mm x 260mm (10.43" x 10.24") Compatible OEM Part #Cross Reference: 13718632502

Works great once assembled
Color: Black
I had an experienced handyman attach the wheels, and even he was confused since the instructions are poor. So allow yourself some extra time to assemble the wheels. However, once attached and placed upright, the wheels are smooth and its very easy to position. And it folds up into a small footprint just as advertised. Looks great. No issues with quality.

Game-changer for me
Color: Light Grey
I’ve had a basement office for a while. I share a big room with my work bench. I’ve always just had a curtain hanging between the two, but after a promotion, I decided it was time for something more professional looking. This divider is awesome, and move-able when I need the space for my workbench activities.
The frame is very sturdy - impressively sturdy even. The felt walls are thick enough to take even heavy duty tacks.
There are three things that could make it even better, but none of them are enough to knock a star off my review, because this is truly a quality piece of office gear.
1. Put a magnetic strip on the top bars so that you could hang a little heavier items or add magnetic hooks. I plan to buy some magnetic tape to allow for this.
2. Allow the panels to be locked at the top. The locking wheels do a decent job of keeping everything in place, but if you could also lock the top of the frames, it would greatly increase stability. Note that it is already quite stable, but the top locks would make it very similar to actual cubicle walls.
3. Put a swivel caster on the middle wheel bars. This would allow you to configure the panels and the “feet” at angles other than 90 degrees when desired.
Again, these suggestions would take a fantastic item and put it into 6-star rarefied air. It is truly a great product as-is, but I would gladly pay another $100 for this item if it had these additional features.

Flimsy and cheap screws
Screws snapped off when I tried to drill htem in and no matter how I try to get the leg pieces in they will NOT stay. Falls apart, screws snap off, the middle axle holes arent even lined up so you cant install one of the pieces in the first place.
