If you have an aftermarket header, chances are you are getting a Check Engine Light (CEL). The new ZPI 02 Simulator effectively removes that check engine light and helps make your car run better. It is a smart 02 simulator meaning it learns your cars characteristics and adjusts your air/fuel ratios.

The 02 Simulator installs into your S-Pipe and requires minimal wire splicing. A wiring diagram is included with the 02 simulator. Installation can be performed in minutes!
