Great product, easy install. Thanks SD!
SD had much better quality product than Ford and easier to install.
After watching the install on YouTube, it seem to be a better buy for me.

Product was shipped within a timely manner and delivered early. Plus there was a free sticker in the box. 10/10 would order from Sinister again.
My boyfriend really wanted this for his truck and has mentioned Sinister Diesel specifically so I knew this was what he wanted when it popped up on Google.

Install it correctly and it works. No it will not give you tons of HP or torque but yes it does improve the performance. Looks great as well.
My uncle has used sinister on his Powerstroke and he’s never had any complaints. They’re top tier with customer service and instructions in my book and can’t go wrong with the look of the products. Sleek and clean.
I want better airflow and to get rid of my stock intake. If you’ve seen a 6.7 intake, you know the jumbled mess it looks like under the hood.

Just received my level kit and now ordered my intake. Great company and badass products!
Why Trust Verified Reviews?
Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.
Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.
As a consumer, here's how you can tell the difference:
Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.
Unverified reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.
So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
