It was a little hard to get on but it was worth it. Definitely to feel the power there once I got the new piece on and get that power delivered to the turbo and you can't beat the cool color on top of it. Sister diesel is awesome!

I wish I didn’t have to use it, but I guess it helps keep my check engine light off

The color definitely looks sharp. But I am disappointed in not having a way to help the air flow issue
5 days ago - TX
There is not enough help that can be provided for 2023 Ram 2500 6.7l trucks. My CEL came on immediately after installing cold air intake pipe and filter. Followed instructions and it won't go off. I have reached out to K&N and they are working to fit a larger air parameter MAF sensor if I purchase a tube and filter from them. I don't really want to spend another $500 but if they guarantee the CEL to go off I will definitely go to K&N Sinister Diesel doesn't have a product to help the influx of more air into the turbo?

Really good quality rebuilt ficm. I trust this one much more than one from auto parts store for a similar price. The grey paint is a nice touch, makes it feel premium too. Once installed forscan shows rock steady 48v all of the time, under load, at idle, cruising etc.

You were backordered customer waited. Long time wasn’t notified that there was no back order then you still did your standard shipping products great always loved the product. Would’ve been nice to know if there was a backorder on the part took forever to get customer service never get the email so I couldn’t track anything and never sent me information after several calls.

Why I choose your company pricewise is good. We do prefer it’s a good product especially for the Ford 6.0 there’s always bulletproof.com but if you want to split the hair for the cost, you’re way more cost-efficient.

Several calls email customer service cannot get right after several calls never input the email right never got tracking information. Never notified it was backordered put way behind schedule on the customers vehicle because we were not notified. I understand if it was on backorder to make up time you could've had it overnight delivery for the inconvenience, since we were notified

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.
