The installation was more difficult than I thought it would be, the design of the Sinister Diesel Cold Side Charge Pipe for 2011-2016 Ford Powerstroke 6.7L (Gray) is a two piece install and the factory plastic design was three piece. Getting the top metal charge pipe to fit into the lower hose and then sliding the metal end onto the discharge port of the turbo was a nightmare but I (72 year old geezer) got it done in about 2 1/2 hours. If I had to do it again, I could do it in half the time with my learned mistakes. I will say that, once installed, I realized that the old plastic pipe must have been leaking for some time. I immediately noticed a huge improvement in performance and boost was easily 25% increased with acceleration. I think the plastic had been deteriorating for a long time with small leaks likely impacting boost. Very happy with the end product but wish the install had consisted of three pieces with an intermediate hose that would have greatly simplified installation.
I ordered the Universal Replacement Reusable Air Filter, 4" Inner Diameter from Sinister Diesel and this is a great product. Received on time and good pricing as well. I recommend Sinister Diesel and would buy from them again!

Great product for the money, fast shipping, always arrives on time, would recommend to anyone else looking for a well made part for your diesel truck
Got exactly what I ordered, the fit was perfect, the quality excellent, shipping fast. Service spot on.
They had the cold air intake I wanted, and expedited shipping to get it to me on time to get it on my truck to complete a job I was having done. Nice guys, too!
I am approaching 60 days now since purchase. No excuse for this. I have ordered, machined and suffered one covud outbrrak in facility with 6 axis port main man doing my cylinders. I have received over 9000K of products with other main diesel shops, well before Sinister Diesel. Unfortunately I have every other part in my build sinister and needed to brand suicide colour match.
Easy search bars easy navigation. I despise computers and online shopping. I will usually use in store service to order my parts they don't carry. This was simple. Ordered ebp sensor, pigtail and blue spring upgrade for fuel all fit like a charm. Seem to be working as well.
Product is great, arrived just as expected. Only slight issue is the installation instructions were online. Made it a little difficult to go back and forth to view.
Product is well designed and relativly easy to install! The only minor complaint is the quality of the clear plastic cover, the holes are a little off!
Great service very easy to install my parts!
Awesome instruction manual!
