i just got a 91 rx7 non-turbo 5spd, the car had been sitting for two years. I replaced a lot of the norms, such as fuel and oil filters, and i added a cone filter on the intake and took out the air box. does anyone have any suggestions on what they would recommend to be the first bolt on i should buy? are there any seals or any other things i should replace because it sat so long?

just put a K&N intake in inplace of the old one and see how she runs
