Sadly, any standard cone filter won't work if you have the enclosed intake from HKS. I am trying to find a suitable replacement.To answer your question, the replacement filter for the HKS Mushroom is the 200mm Red Wet Oiled 2-Layer model (70001-AK032). The 200mm Green Dry 3-Layer filter (70001-AK022) is also compatible. The filter unit itself is the 200-100mm model, 70019-AK112.
While I absolutely love HKS as a tuner, I despise those mushroom foam filters they use. They need to be replaced every 3-5k miles, don't filter that well, don't offer a performance advantage over cone filters, and there's countless horror stories over the past two decades of little bits of the foam breaking up and being sucked into turbos on many different platforms. Even GReddy stopped making similar foam filters and started making traditional cone filters.
Luckily, you can replace the mushroom foam filter with what I believe is a 100mm/4" inlet cone filter, given that it's not too long and will fit in the HKS intake box. Worth looking into what would fit from K&N, AEM, Airraid, aFe, Green Filter, etc.
Someone in our local Supra group actually did just that with the MST filter from MST's Supra intake:
Any luck finding a suitable replacement cone filter for the enclosed HKS intake?
Was it installed correctly?Hate to revive such an old thread, but I figured this was worth mentioning to others running the HKS Racing Suction intake as something to be aware of.
I recently re-installed my OEM intake and upon inspection of the HKSā coupler, there was noticeable debris (dirt, sand?, particles). In the photo attached, I had already cleaned off the larger bits (0.5mm-1.0mm in size).
Though I love the craftsmanship and quality of the HKS intake, Iāve become skeptical about using these mushroom filters. These are meant to be changed at a much shorter interval of 2000-3200 miles and mine was due for a replacement. I donāt live in a particularly dusty area so I was surprised to see this after breaking 2000 miles.
I have not checked in a while but not that I ever noticed, I'll take a look when Im back in town.
