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.

These work!
Size: M (up to size 9)-Beige
I’ve had dry cracked feet my whole life. Tried these last night with lotion from Trader Joe’s and literally overnight my feet are the softest they’ve ever been. I put a pair of socks over them and went to sleep with them on. Hard to walk around with all that slippery-ness but worth it! 10/10✨👌

Do not buy these
Color: Nude, Size: Women 9-13
These are terrible. They are designed to walk in. The first day I tried them on I walked about 20 steps and they basically ripped right off my feet. I didn’t think much of it and just thought ok I won’t walk in them I’ll just wear them to bed. The second pair that came with the order I wore to bed that night and woke up with holes tore in them. Terrible product

These are form-fitting and durable. Wearing these keeps the skin moisturizer in place so it can be effective.

Great Results
Color: White, Size: Women 9-13, Color: White, Size: Women 9-13
The Jfrhuds Moisturizing Silicone Socks work very well. I ordered the white 2-pack in the large size 9-13, and each came packaged in an individual zipper bag.  I wear a women's size 9-9.5, and they fit me perfectly.  I can see how they have enough stretch to fit larger sizes easily and comfortably. These socks are a lot thicker and heavier than I expected.  They are rubbery with non-slip treads on the bottom.  As soon as I put them on my feet, they actually felt very moisturizing and almost wet, even though I had not put moisturizer on my feet first.  Plus my feet felt cold at first. It was different than I expected, I had never worn this type of sock before, and it was an interesting sensation. They work great, and I am sold on the benefits of these socks.  I wear them to sleep at night and dodn't walk very far in them.  They seem pretty sturdy, but I don't want to push it and will just use them for their intended purpose.  My feet weren't super dry or cracked, but the socks really helped revive them and make them super soft again.  I love them; they are great for self-care and would also make a wonderful gift.
