Customer Q&A
Ask a question to 1A Auto customers who purchased the product
Can this be used for upstream and downstream?
Cosmo C May 21, 2018
i used it for downstream as the connector style and cord length is different for the upstream.
W E May 21, 2018
sorry meant to mention its on an 03 impala
W E May 21, 2018
Looked at the product number on a 03 impala this is for upstream behind the headers and distributor cap. the downsteam (behind the catillatic convertor) connector is a different connector head so this is only for upsteam on an 03 impala but varies depending on the vehicle its being used on. best to do is look at the vehicle fit chart for your particular vehicle.
W E May 21, 2018
yes it can...
