Mazda Filter Sock Installation Instructions

I have an aftermarket hood that is vented and the timing of this release was perfect to make sure my intake filter stays safe from the added environmental ingress. Pre filtering dust and debris will also help keep the filter nicer for longer and help water from causing issues.
After purchasing the CorkSport air filter cover, I was impressed by its quality and functionality. The cover is well-designed and fits perfectly, providing an added layer of protection for my air filter. The water-repellent feature is particularly useful, especially during rainy weather or when driving through wet conditions. Overall, I'm very satisfied with this product, and I would recommend it to anyone looking to protect their engine and air filter.
Make sure to follow the instructions or else weird things might happen ._.

Great product, keeps the dirt and such out of the filter :)
Easy fitment and no more worries about Floridian sand caked in the filter.
Installation was a breeze. Filters out the sand I hope. The hellscape of Florida does this.
