Sinister Diesel Coolant Filtration System for Ford 2003-2007 F-250, F-350, & Excursion 6.0L Diesel with All Hardware – No Part Removal or Drilling Required For Filter - Easy Installation

TL;DR - Buy this part and you will not regret it. Top-notch quality and customer service. The extra ~$35 you spend here instead of buying a Mishimoto supports American business.Sinister Diesel is a company that can truly stand behind both their mission and product. What I received was a kit of high quality, American made parts that were easy to install with instructions and all necessary parts needed. Moreover, there are a plethora of video tutorials available on YouTube which make this installation as easy as the product title/description suggests.If you buy from this company you are clearly an individual who cares about quality, credibly sourced/manufactured parts for your vehicle. Sinister Diesel will be extremely quick to answer any questions/comments/concerns you may have about your purchase or their company in general.

Like other Sinister deisel parts the quality is amazing. I have had my share of parts that do not fit or instructions are vague....not the case with Sinister! High quality parts, instructions that match the vehicle, the parts fit the way they are supposed to. With that said it is understanable why thier parts are so expensive. Thier parts are more expensive but like the old wattage says....you get what you pay for. I love Sinister Diesel....I do not purchase all my parts from Sinister because I can't afford to for every part....but I try to buy the parts that really matter from them.

Installed this Sinister Diesel coolant filter system on my Powerstroke 6.0L diesel after I put in the third oil cooler in my truck (in the last 12 months). I was impressed by the quality of the machined parts, the silicon hoses supplied, and the installation process. Installed in about 5 minutes, looks great, and I am very happy with both the product and the seller. Many thanks.

Couldn’t believe how quick and easy this was to install! Less than 30 minutes from start to finish! This is a must for your Diesel engine! All high quality! Looks amazing as well!!

This is one of the easiest kits i've ever installed. Sinister does a great job with making sure things fit and is easy to understand.

Easy install 2003 F350, looks good, I don’t see why the valves on the line are really necessary but the kit includes them anyways.

It came in a sealed box with parts missing. 2 of the 4 hose clamps needed were not in the kit despite them being shown on the what’s included paper work. The installation was easy one I supplied the missing parts and adjusted where to T-into the heater hose. The included installation instructions where inaccurate about the real stock layout of the engine bay. I thought I was buying a quality system by not going with the cheapest option out there. Now I’m not so sure. It seems like it’s just more expensive.

Hoses didn't last a season..cracked and leaking. BUT Sinister Diesels customer service is fantastic and is sending a replacement. Great customer service!
