This might work for R18's but im not sure. With the world going green these days I have decided to take another step towards joining the "going green phenomenon". I have cleverly figured out a way to make the air in our cars better using existing technology. This is especially useful if you live in a high smog area like EL PASO TEXAS. I am doing test runs now to determine if My breathing is any better having one of these conversion devices installed directly in My car. These devices can be had for under $10 at local wal marx's and other stores.
Due to the sensitive nature of these devices to their environment I have to bring it into the house at night so it doesn't get too cold, otherwise performance is severely degraded. You can view a live webcam of the device by going to this website below.
