That's a nice blue, looks like Subaru world rally blue.

What's the paint code to that color? I'd like to paint my intercooler piping on my subaru that color!

Other color options?

No no I own the blue !

Lemme guess, blue?

I would just like an O ring to count on!!

I’m just here for the comments.

Better get rid of that red cover over the battery terminal you don’t own red

And to think I wanted my 7.3 to look like this some day. So glad I decided to hold off on starting my project sooner. You lost a customer here...

Don’t sue me but I painted my snowmobile this exact color😂🤟🏻🤷🏻‍♂️ “sinister blue”

Do you guys not offer a manual transmission? Or know where I can find one

Hahahahaha oh boy that color blue! Look out for this guy those parts are sure to fail soon!

I see swap out the alternator so youll have 1% of the electrical issues fixed on a ford. Iol

Love that cold air wish it fit 97 7.3l

@Drownin_In_Diesel

It's ok. Some Krylon will take care of that hideous looking engine in no time...

That is my colors lady.!

While everyone else is being cry baby bitches, Sinister Diesel I don't see this cap kit on your website for the 7.3 nor do you show that brake reservoir cap which I find interesting seeing as no one else such as Riff Raff even offers that billet cap

I read that this blue shit was aimed more at the Chinese knock offs painting there shit blue, me you anyone can paint our trucks w,e we want it’s the people selling the parts

Lol bunch of haters on this bitch!!! Keep buying your Ebay knockoff garbage

Look better red

Y'all still around??

#backtheblue Happy Thanksgiving.

I’m thankful y’all posted a real useful looking truck. Instead of the same trend with 30x20 inch wheels

All these idiots who don't understand how business works. :/ Happy Thanksgiving.

Happy Thanksgiving. Please stop crying over a color. It doesn't effect any of you at all so who cares.

Happy Thanksgiving!!! #STILLMYCOMPANY

Happy Thanksgiving to you all 🦃🦃🦃

trademarks.justia.com/878/40/n-87840011.html just a little FYI for those who don’t understand trademarks

Reading these comments, it is very sad to see how few know anything about patents or trademarks.

Same to you sinister fam!!

Woah guys that's cummins red.. be careful

Finally a real truck! And not a bro dozin, mawl crawlin, pavement pounder! Take note little boys, thats a real tire to wheel ratio!

Hey is anybody parting out a 93ish Chevy 2500 I’m looking for a gas tank none diesel

Happy Thanksgiving to all🦃🇺🇸

Get better airflow with the Intake Manifold for a 7.3 Powerstroke. These are mandrel bent, for a greater diameter and you can see them being tig welded in this video. If you drive a 7.3, check them out here: ow.ly/vjvM30mDmfw

HEY that's my color Silver WTF !!!!!!

What did it flow on the flow bench? How’s it compare to other brands as far as flow?

Not a bad price for everything, split manifold and new hose connectors with clamps.

Wonder if ford will stop selling blue cac boots and rhe blue coolant boot to a 6.0 egr cooler.......if not they will get sued

What even is post flow

Bryan Tewes This and a turbo 🤙🏻

John Markham DO IT!!!!

Idiots. Have no idea what they're doing.

www.purgeplugs.com/ I’ll post it as fast as you delete it. Just sit back and accept that you’re getting called out on your shitty ass welds.

Lol no one wants that crap even for free

No one wants a cease and desist letter for using blue. Keep your damn care packages! We all know your just trying to trick us in to accepting the letter.

The new Yamaha sidewinder looks sweet! Love seeing new sleds get airtime

Someone needs to photoshop some coal rolling out that 2 inch stack! Be perfect. 🤣

Be some shit whistlin diesel would do

Taking a dive like your company just did

Do u have permission to use this photo. I do not even see any photo cred.

You have rights to use this photo from cat

Caterpillar gets sued for jumping into the clear blue sky 🌌

About as legit as your phony ass company

Guys stop picking on sinister... your gonna make them run back to their safe place 😂

Go home dozer your drunk. Lol

I’m surprised someone hasn’t photoshopped the logo underneath the dozer yet

That dozer's going to drop harder than your sales.

The landing is what your POS company is going to look like when this shit storm is over

Cat owns the rights to that picture I'm calling them now

Better not paint my truck blue🤷🏼‍♂️

That shade of yellow is trademarked... Note the word SHADE. you might as well be HD trying to trade mark sounds...

I bet it has the ford 6.0 🙂

Cat letter is coming for you using their unauthorized logo

About as legit as your products

Anythings possible when your not using any blue Chinese crap

Still not going to be as rough as your next year's sales

Heres a demonstration of how fucked sinister is.

Shadow is wrong. Nice photoshop.

Hope y'all have a patent on that sky

Evidently you’ve never seen a Combat Engineer operate a bull dozer! Nasty!! 618th Engineer Company, light equipment... Airborne
