I have not but the fact that those A pillar pods are made from Honda parts is interesting. Blending a gauge pod into an AC vent is cool too. In those applications I assume the air duct is reduced by addition of a baffle so all the air that port was to deliver does get out.
His products are hit and miss. Some of the quality is decent, others are horrible. Yes, he modifies OEM parts but at the same time, the pods that he uses is just 2" PVC epoxyed into place with body filler to blend.
