I like Defi 'cause they match the oem gauges. I like AEM because they are easier to install, with support and instructions, And they have clear, quick reading displays.
I don't think there is anything really wrong with Autometer??
I think If I had to buy them again, I would look at Zeitronix. I like the displays more over the gauges.

 

guys question you know the evo 9 has the three original gauges under the radio if i put the aem air fuel/ratio and boost in a pillar pod gauges i have to eliminate those. thanks for your help
