I have been looking around for an a new air filter for my 87 T II and have been having problems finding one. All the filters that I see are for a n/a and not a turbo. Can i use the n/a filters or are there only a few that will work on a turbo? Also which filter will do the best job. I just got the car 2 weeks ago and so far it is running great. Paid $100 for it and everything works fine. All the equipment seems to be original right now so I am looking to upgrade the intake now and then the exhaust and wastegate... this summer. Any directions to go for the intake?

As far as I know, the 86-95 RX-7 replacement filters are all the same size. This is a good drop-in filter:

More complicated options include:

1) Converting to a universal filter. You can either get a kit for this

or do it yourself with an adapter and a filter of your choice.

2) Add on a "cold air" intake. Once again, you can make it yourself, or buy a kit.
