Ordered High comp piston, cam, airbox mod, and new ECU and wow did it wake the grom up. The TBR exhaust sounds awesome now. Great communication and fast shipping on David's end. Will suggest to others and be going through DHM in the future.

The DH Motoring Stock Airbox Mod Kit will allow you to maintain your stock airbox but with the flow of an aftermarket intake! This is perfect for sleeper builds or for offroad riders that want the protection of a sealed box instead of an open filter. Using a KOSO intake tube that was originally designed for their 34mm throttle body, we've developed a billet eccentric adapter that allows the tube to be used on the stock throttle body.  

You can purchase the kit in different configurations if you already own certain parts:

  • Adapter Only (If you already own a Koso tube)
  • Adapter and Tube (If you plan on keeping your stock filter or already own drop in filter)
  • Adapter and Filter (If you already have a Koso tube but need a Koso filter)
  • Adapter, Tube, and Filter (the entire kit if your airbox is completely stock)

Key Features:

  • 6061 machined aluminum adapter
  • Stainless steel set screw for corrosion resistance
  • OEM-Styled larger inlet tube 
  • Optional Koso Hurricane high flow air filter for the stock airbox
  • Increased top speed 
  • Increase throttle response 
  • Increased HP and Torque 
  • Retains OEM Intake temp sensor placement
  • Retains stock airbox for increased protection against the elements

If you don't already have our flash, this setup along with your aftermarket exhaust pairs extremely well with our Stage 1 Reflash or Cam Package!
