My Ractive intake w/ HKS AFM Cone Filter Adapter. I bought the Ractive filter for ~$35 and it came with a heat shield, don't know how well it shields hot air though. I bought the adapter from Cyberspace Automotive for $34 I think. When ordering it you have to specify whether you have a rectangular or square opening on your AFM, that's why they have two different prices. Mine was square and of course it ended being the more expensive model. I suggest fabricating a mount for your AFM so it doesn't flop around, since you will be taking off the stock air box that was normally bolted down. You can use the old air box pieces to mount it if you want.
