newb question
 

hey guys, just wanting to know since the K&N FIPK says its for 86-88, if i installed it on the 89 - 92 RX7's would it install fine, or do you gotta do some extra work? thanks in advance.

I don't know what a K&N FIPK is, but I assume its a cone filter that you intend on using to replace the stock air filter and filter box. For S5's the new filter will fit right on as it is. For S4's you will need an adapter the bolts to the AFM and then the filter fits on the adapter.
