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.

Works great
Be careful NOT to get it on painted surfaces it will remove the paint. It does exactly what they say it does and if you follow the directions to the letter you won't have any problems

Worth the time and effort.
Perfect solution to my faded out, sun damaged gel coat. Follow the instructions to the letter for a factory-like shine. One bottle was barely enough for our 22' Winnebago, another bottle for our 29' Cabin Cruiser. Many compliments on the shine.

A quality product which will clean an oxidized fiberglass trailer in preparation for the application of Poli Glow
I used this to remove the Poli Glow previously applied about two years ago to my fiberglass trailer. It seems to do a slightly better job of removing the PG than the other Prep solution, but I didn't do a side-to-side comparison. And the surface never achieved a completely uniform appearance after the stripping, although this may not be possible because of differences in the remaining gel coat surfaces. I also completely washed the trailer with soap & water after using this stripping product. I didn't do this the previous time and thought some of the prep compound may have been left on the surface resulting in a shorter life. Time will tell. Note: it is still "work" to strip the trailer, this is not a "magic" solution, thus the 4-star rating. But it, along with the Poli Glow, was the only way to get my oxidized trailer to look shiny. All the other products tried failed to bring a glow. I will purchase it again when redoing the trailer.
