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!

Ultra-Light, Cooling & Comfortable – Great for Night Sweats!
Team Name: Cooling Comforter, Size: Full/Queen(90"x90"), Color: 01dark Grey
The DOWNCOOL Cooling Comforter Set (Queen Size 90”×90”) is a fantastic choice if you tend to sleep hot. The comforter uses advanced cooling fabric technology that absorbs body heat and helps reduce skin temperature by a few degrees, making it ideal for summer or warm climates.
The material feels cool to the touch, lightweight, and breathable, so you stay comfortable without feeling heavy or sweaty. It also features moisture-wicking and quick-dry properties, which help keep the bed fresh throughout the night.
The set includes 3 pieces (comforter + 2 cooling envelope pillowcases), and the pillowcases add an extra cooling effect around your head and neck. The fabric is soft and skin-friendly (often OEKO-TEX certified), making it safe for everyday use.
It’s also machine washable and durable, maintaining its cooling performance even after multiple washes, which makes it practical for long-term use.

Cool and comfy

So comfy, lightweight, soft and yes, cool to the touch. Doesn’t stay cool though for long exposure but great for sleeping with animals or others.
