Just installed the RX-4870
and with a little cutting it looks great. First off you have to cut a support ring that fits over the end of the filter(replacing soon with aluminum). I choose to use the OEM filter by cutting away all the paper and cutting out all but 1/2". Then had to cut about 1/4 - 1/2" off the lip of the lip so the filter would fit. Overall took about 30 minutes. This allows are to come int from the snorkel and from the driver side of the airbox. Puma speed has other pics in the ST
I think this provides all to performance of the SRI and retains the stock look.
