The New AEM X-Series Widebands are extremely fast. This speed gives you the ability to see individual cylinder events and report this digitally to your tuning system or ECU. The controller’s high speed digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.

AEM X-Series 30-0333 works with HP Tuners, EFI Live, OBDII, & CAN systems.
