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?

The color definitely looks sharp. But I am disappointed in not having a way to help the air flow issue

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

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.

I received my catch can for my 2023 6.7 Powerstroke. Very excited to look up the instructions on putting it on. When I typed in my specific truck, only the instructions for the 03-07 6.0 Powerstroke were available. I had to call on two separate occasions just to get the 2023 instructions. This isn't a huge deal but I could see how this would make it very hard for someone in the future buying this part.

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.
