Ask a Question
  • 2002 ram 5.9, do I need a tune or tuner to run this cai?

    No tuning or tuner is needed for this system. Thanks

  • Does installing this require a tune? I don't have a programmer yet and don't want to add something that requires a tune before I get a programmer.

    No tuning is required with this intake system, even on a completely stock truck it works vary well.

  • Will this fit a on a S362/65/14?

    Yes it will fit with that turbo

  • Will this fit the 5 inch s400 turbo inlets

    Yes but we would need to send a 5" to 5" coupler and not the 5" to 4" we normaly send. Include a note at checkout for S400 5" Inlet Turbo.

  • Can I use my own logo if I send the picture?

    It depends, send me the picture and I can see if we can do it on the cnc plasma table. Sales@rpidiesel.com
