Increase your fuel pressure by 10psi and help your 6.0L Ford Powerstroke run better and longer with the Sinister Diesel Blue Spring Kit with Billet Adjustable Housing and Billet Filter Cap. The blue spring kit is one of the quickest and easiest upgrades you can install on your 6.0L Ford Powerstroke. This kit not only helps with longevity, it can also quiet the engine down, and rev up faster which in turn helps spool the turbo faster. Maintaining proper fuel pressure prevents the injectors from outflowing the stock fuel pump so no air is introduced into the injection system.

The Adjustable Spring Housing is a major benefit for those individuals that are running much larger injectors as this will give you the ability to raise the pressure with the simple turn of a screw. Also, as miles rack up on your truck with this kit, springs can settle, this housing will allow you to return the truck fuel pressure back to the proper setting. Sinister Diesel suggests running your fuel pressure between 55-68psi. The factory housing is constructed of cast aluminum and is known to leak or "weep" from the sides of the housing. The thicker and stronger billet construction eliminates this issue and also adds a little style under the hood.

The OEM plastic fuel filter cap is notorious for cracking. Leaking fuel in the engine bay is just asking for trouble. The Sinister Diesel replacement cap is constructed from a solid chunk of billet aluminum and is machined for a perfect fit and eliminates the risk of cracking. This cap is anodized Sinister Blue for corrosion resistance and features a 1/8th inch NPT port for testing fuel pressure.

Great toy to play fetch with the dogs.
Color: Black/White, Size: Large
These balls are a great dog toy to play fetch with your dogs. This not the first ball I have gotten for the dogs. Just the right size and weight for medium sized dogs. I have less concerns about them possibly choking on these soccer balls versus tennis balls. So I can leave them out for them to play with. The are easy to inflate using the included pump. My only concern is the durability of the straps as my dogs have almost torn off one the straps of the previous ball I purchased.

Westie LOVES this toy
Color: U.S.A, Size: Medium
My pup (Westie) adores this toy. This is actually our second one. The ball itself is resistant but the straps will be obliterated. Would definitely recommend! Totally worth the price!

Not durable
Color: Black/White, Size: Large
If you have a dog who likes to pop things then this toy isn't it. Within 5 min she had this ball popped. It was made to sound like it was durable for this type of thing but it definitely is not so just be aware. Now if you have a dog who doesn't pop things easy then this would be a good toy
