$40 Randall/Cowl Miata Cold Air Intake

This is a cheap and effective way to increase power and add sound to you miata and it only costs about $40, much cheaper than alternatives out there that cost almost $300.
Correction, I used some gasket maker/RTV to get a better seal for the temp sensor. Also you will need to drill a hole in the connector appropriate for the diameter of the portion of the sensor nearest the base.
