This system is made for stock sensor calibration. Meaning this system works perfect with no check engine lights, no matter if your truck is stock, or highly modified

Has a bolt in heat shield that is very well sealed to keep underhood temps away from the Filter, it provides a fresh cold air supply straight to the filter for lower egt's and better performance. It is normal to see 150-250 deg drop in egt's with this system.

We use only the best filters on all our intake systems

These are Custom built to order,  so it takes 6-14 days to ship out, depending on how many orders we have that week.



Ask a Question
  • Which filter is the blue one shown in the pic? I like the candy blue but would want a blue filter to match. Is this intake better than the sinister diesel intake you offer? Do you have any coupon codes for the intakes for a 2012 Cummins?

    It is the amsoil filter. Yes it is better then the sinister as the sinister is only 4" and has no heat shield. I dont have any sale right at this time, but we do from time to time 

  • Any promo codes for 4th gen Dodge intakes

    We can do a free T shirt, but other than that we dont have any sales right now. Just include a note at checkout for free shirt and list the size you need. Thanks

  • Is this CARB compliant?

    No it is not

  • Is the S&B dry filter reusable/washable? Or does it have to be replaced every so often?

    The S&B dry filter is not cleanable

  • I'm really interested in you air intakes for my 05 but I dont want a loud turbo whistle.any options? Thank you.

    All our aluminum intakes will have more turbo whistle, i would recommend the banks intake or injen intake systems, they also flow real well. Anything with metal tube will have whistle

    It is mounted on the heat shield to get a reading of air temp entering air filter. No check engine lights.
