## Description

Direct from manufacturer. Made in the USA.Filter material: 100% monofilament polyester with water repellent finish standard on all pre-filters.Closed top, round pre-filter.Measurements: 8 inch diameterFits HKS Mushroom Style Cold Air Intake Filter

Review: Seems like a quality bit. - I’m using this on a 97 Aristo V300 2JZGTE after installing a HKS Racing Suction intake on the stock twin turbo intake piping. The filter size is a 200/100. The fit is nice and tight. There appears to be a very strong elastic that will hold it in place. It didn’t seem to change the sound of the intake at all and after a few days of having it on the filter I noticed a good amount of fine dust in it too so it actually appears to be a good pre filter. The logo is nice and doesn’t look cheap. The over feel of the material seems very durable. I was only going to use this during wet weather but I may just leave it on all the time. My biggest concern when I purchased it was how it fit and honestly I can say it’s very snug. Accurate measurements were taken and it fits like it should. This seems like a good product from my initial instal and it’s not cheap looking in the engine bay. My initial assessment is that it is a good purchase. I’ll update if I have any issues.
Review: Exactly as described - Fits perfectly on the HKS mushroom air filter. Great quality and works great.

### ⭐⭐⭐ Elastic fits very loose on a hks 150-80
*by B***S on February 9, 2025*

Filter media feels nice but fitment is "eh" at best.. not bad enough to not use but not good enough for me to recommend or buy a second one
