Features & Product Details

The Cobb Tuning Post MAF Hose will join the stock airbox (or optional COBB SF Intake) to the turbo inlet tube by replacing the stock rubber piece. The factory post MAF hose is corrugated which can make for a rough air transition. The Cobb Post MAF Hose has been designed to have a slick interior wall which allows a smooth volume of air to get to the turbo. This results in better performance, and improved throttle response. 

The Cobb Post MAF Tuning Hose is crafted from a 4-ply silicone construction and has just enough compliance to bridge the factory chassis mounted airbox, to the relative motion of the boxer engine.  It has steel reinforcement construction to prevent collapse under maximum load, and to ensure performance for years.

COBB Tuning Post MAF Silicone Hose Black ( Part Number: 712010BK)
Tight fit for FXT  11 months ago
Sits in an odd position, and doesn't totally line up with the factory airbox or the turbo inlet. still seals up and does its job, so its more of a cosmetic issue.

  • Q: Fitment to factory air box?  Trailer Park Ninja2 years ago

    Hello, I currently have a Fuku Works turbo inlet and the factory air box in my '059-2x. The stock post MAF hose is placing a lot of stress on the lid to the factory air box as well the first elbow on the turbo inlet hose. Will this hose properly align with both the turbo inlet hose and the factory air box as well be the correct length? Thank you!
  • Q: tune?  mikenice1134453303 years ago

    if I use this with the cobb sf ram intake will a tune be necessary?

      A:  Tuning is not necessary for a post MAF hose, but tuning is required for the SF intake.
