FILTERWEARS Pre-filter F237L For HKS Mushroom Style Air Filter

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.

Fits perfectly on the HKS mushroom air filter. Great quality and works great.

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

works as intended

Stay away if you want to waste your money its great if you need a shower cap for your hair lol. Way to big for the filter they say it's for.

Fits perfect on my HKS mushroom filter

The media could not be loaded.

Fits but not tight, use it on my mini bike and will probably fly off some day if I don't modify it.
