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.

Excellent Sound Deadening Material!
Style: 10 SqFt, Style: 10 SqFt
I installed Kilmat Sound Deadening in my truck, and I’m extremely impressed with the results. The material is thick, pliable, and easy to cut to fit doors, floor panels. It sticks very well to metal surfaces and doesn’t peel, even after heating it slightly to make it more flexible. After installation, I immediately noticed a reduction in road noise and vibrations. Worth the money!!

A Must Have For Car Restorations!
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
I have been installing this matting in my 74 Datsun 260Z restore and very pleased with the ease of application and overall quality. My car has bedliner coating inside and this stuff sticks extremely well and is easy to trim and shape as well. I have just started installing it and using the rollers to work it in place but I can already tell a difference with just the little bit I have added....has reduced the resonance in the metal already. It's not a fast process but know it will be very rewarding once complete.
