We at Damond Motorsports have developed a kit which allows the factory Focus ST intake manifold to be adapted to fit the DISI head with the ability for individual port fuel injection. The Factory ST manifold has been proven to flow incredibly well and evenly, and is available at a very low cost. This kit has been put through extensive testing on the street, the track, and the dyno to provide a great solution for more equal airflow distribution into the cylinders and allowing access for auxiliary fueling. 

Benefits of the ST manifold:

✓ More flow

✓ Better flow balance

✓ Lightweight

✓ Low cost

What's included:

-ST Manifold to Mazdaspeed DISI head port injection adapter, fuel rail, and adjustable rail brackets to fit 34mm or 48mm injectors. The injector ports on the adapter and rail are machined to a 14mm bore. The rail is machined either end for -6AN o-ring style fittings or plugs.  

-A vacuum block that mounts to the ST intake manifold is included, along with the necessary fittings and hoses to connect into the factory vacuum lines.

-The factory PCV connection on the ST uses a convenient quick connector.  Included will be that pre-assembled with hose and a fitting used to screw into our check valves if you have our Mazdaspeed OCC kit. If you do not run a Damond Motorsports OCC kit, there’ll be an adapter included so you can connect into your PCV line.

-A dipstick mounting bracket

-Hardware to mount and secure components

Optional items:

-A pre-wired throttle body cable extension. Since the throttle body is in the middle of the ST manifold pointing downward, the factory throttle body connector will not reach to the new location. This extension uses OEM connectors to give you a plug-and-play solution for extending the harness to the new location.

-Modified ST manifold. In order to fit the manifold onto the Mazdaspeed, not only is our adapter needed, but the manifold itself needs to be modified to fit. This is mainly trimming off a few excess tabs, and removing material around the left-most mounting point for clearance around the belt idler pulley. We start with brand new OE Ford manifold and modify them to order. 

 Notes:

-Not included are injectors, fuel lines and fittings, controllers

-VTCS must be disabled to prevent a CEL. 

-There is no provision for an EGR tube with this kit, or manifold.  You must have an EGR block off.

- An FMIC is required.  For the hot pipe, under-route kits are the best option, but kits with hot and cold side piping on the driver’s side may work as well. 

-If ordered with a modified manifold, please allow a few extra days for shipping, as the manifolds first have to be modified. Limited numbers of manifolds are available.

Makes everything look so much clean
got these mostly to deal with all the random cords around the house, and they made a bigger difference than I expected. They’re simple, but they actually do what they’re supposed to. Once everything is tucked inside, it instantly makes the area look way more organized and less cluttered. I’ve been using them for things like power strips and extra cords, and they hide everything really well. They’re lightweight but still feel sturdy enough, and the lids stay on without being annoying to open. Pros: Really helps clean up the look of messy cords Easy to use, no setup needed Simple design that blends in Cons: Not huge, so larger power strips can be a tight fit Plastic isn’t super thick Overall I’d definitely recommend these if you’re trying to make a space look cleaner without doing anything complicated.

Great Space Saver!
I purchased these for our family room charging hub and honestly wish I had known about them sooner. They are sturdy and very kid proof (at least for my kids). I love the push and lift design so little hands can’t just lift it open and they hold a lot yet blend in.

Handy boxes hides wire clutter.
Does what it is meant for. A bit hard to open once the top is fitted.

Clean, secure cable management
These are good cable boxes that close securely. They hide cables very well and look clean and blend into the home well.
