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!

They're okay, but they're quite bulky.
I liked the design and overall application of these, but they don't fit my needs. They definitely work well at protecting my hands from freezing weather, but they are way too bulky for regular motorcycle use. In my opinion, I feel that these would be much more suited for a snowmobile or ATV.
If you treat them as what they’re mostly designed for — ATV/snow-related riding or cold-weather utilitarian use — these gloves are a solid buy. They deliver warmth, weather protection, and decent control through the TPU windows.
But if you put them on a fast street motorcycle or expect “motorcycle-glove” levels of control and feel — they’ll likely disappoint or even pose safety trade-offs. In that context, lighter and more control-oriented gloves would probably serve you better.
The reason I'm docking stars is because they're marketed toward motorcycle users, and they;re very impractical. The durability seems pretty good, as I've taken them out and even had a couple of rocks/road debris hit the TPU windows with no scratches or punctures. They're not super comfortable to use at highway speeds, especially since they fit so loose, and they tend to press my front brake/clutch which is very dangerous. I personally cannot recommend this product for motorcycle use, unless you already have handguards, which will probably negate the need for these at all. Invest in some good heated gloves and/or heated grips, and I think you'll be much safer and better off in the end. For the price, I think this is a good value, but they're just not for me.

All ATV owners need these.
These gloves are fabulous. Anybody having fun on a ATV need these. With my hand warmer and these gloves, I don’t wear anything else on my hands. They are great.

handlebar mittens
Too big. If using during snow plowing they are a burden due to need to take hands off controls, and shift from forward to reverse. Might be okay if just riding around on trails, etc.
