The 4-ply silicone construction has the right compliance to bridge the chassis mounted airbox to the violent motion of a boxer engine being driven in anger, while the steel reinforcement prevents collapse when the turbo is drawing maximum vacuum at wide open throttle.


Say hello to the new COBB Post MAF Hose for the '02-'07 Subaru WRX! The COBB Post MAF Hose balances form AND function with its smart appearance and turbulence taming characteristics. It joins the stock airbox (or optional COBB SF Intake) to the turbo inlet tube by replacing the stock corrugated rubber piece, arguably one of the most aesthetically challenged OEM parts in the engine bay. The sleek exterior is easy on the eyes while the slick interior is airflow friendly. Make your turbo happy! Compatible with FXT only when used with COBB SF Intake.

  • Replace Stock Corrugated OEM Tube
  • Decrease Turbulence in the Intake Tract

Customer Photos

Subaru Post MAF Hose is rated 4.4 out of 5 by 5.
Rated 4 out of 5 by from Solid Product, BUT Doesn't Fit The FXT! ⅘ Stars because this looks and feel like a nice hose and sells for a decent price, but it didn't fit my car as advertised. I tried to install one of these on my '04 FXT, and it was not long enough to bridge the gap between my factory air box, and my factory turbo inlet tube. This is because this part was made using measurements from the WRX. The air box is positioned much higher in the FXT. Kyle at Cobb tried to fit it on an FXT they had in their lot, and confirmed that it is too short. (He was very nice about it and took great care of me, btw.) So, until the site is updated to reflect this, don't be fooled! Do not buy this for your FXT!

Rated 4 out of 5 by from Quality part but poor fitment As other people have said, it does not fit the FXT. Cobb shouldn't be saying it fits the stock airbox.

Rated 5 out of 5 by from Straight forward Easy install, easy fit, felt like very good quality, but easy to get dirty (not that it matters). A little expensive, but I wasn't trying to shop around either.

Rated 4 out of 5 by from frustrated purchased the "afta maf" how ever I try this way and that way its to long. seems like I would have to cut 1/2" to get it to slip onto the stock air box...
