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 power steering pump. 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.

Nice shirt. Wrinkles alot.
Size: 4X-Large Big, Color: Light Grey Vertical Stripe
Like the style and construction of the shirt. Fit and finish are as expected. Unfortunately the fabric wrinkles easily. Definitely requires ironing. Wish this shirt was a wash and wear but it's definitely a wash and iron before wearing shirt. Otherwise I have no complaints. Fabric is lightweight and could be used in summer as a dress shirt.

Very nice shirts
Size: Large, Color: White
These are a heavier fabric than I was expecting but that’s fine since it’s winter. They barely shrink being washed in hot water and dried in a hot dryer. I was actually hoping that they would shrink a little more after losing 40 pounds. But they shrunk just a little and they fit just fine. Also, if you take them out of the dryer immediately there are very few wrinkles.

Dress shirt
Size: XX-Large Big Tall, Color: Powder Blue
The material is a nice quality and the color is very close to the picture but I think it’s a bit darker in person. It definitely doesn’t fit like a “tall” should though but I think if we would have sized up it would have been to big. Overall it was an ok purchase for what we needed it for but it is a bit short.

Fit check = great
Size: X-Large, Color: Light Grey Vertical Stripe
Happy to finally find a great shirt fit for both business and casual looks. This shirt line is made in Sri Lanka (not Bangladesh). It has a great fit around the shoulders and chest for a 40 year old American male. It fits true to form and was recommended to me directly by Grok AI based on my exact waist, chest and neck measurements. It doesn't pull tight across the chest, and fits really nice with a sport coat. It's comfortable and breathable, the fabric is thick and high quality. You can wear this tucked or untucked depending on the attire you need. I bought 2 and will definitely buy the rest of the color line up. I'd love to see more colors and patterns available in this fit.
