I contacted VARAMAIR since it is somewhat of a variation of the FCA RamAir assembly except for the top cover and a bit of extension to the front skirt. I was asking whether or not they include, bedsides installation instructions, the need for a mod or reflash to the ECU/ECM for optimum air, fuel and ignition giving the increase in air. Response - To date ( 5 days )... nada, zilch. While I still believe the RAM, Ram Air is great aesthetically, not sure if I'll be opening the hood much at local cruise night... but would like an increase in torque which could translate into mpg.
In reviewing the RAMAIR installation instructions I find a "tell" which could be ( note "could be" ) FCA's window if later there is an engine ( lean burn ) issue. I've included that in the attachment.
As a long time ( I mean a really long time ) Mopar gearhead I like the forums to get info . Thank you.
