Did the job, but was very hard to install 90 degree elbow. Pipe did not want to go down inside totally, if elbow was just 3/4" longer, would have been a breeze to install.Had to hold up on elbow and tap downward on pipe and i barely hit and bent pipe. Not super happy .also would have been super helpful if you noted the recommended position of the clamps

Fit, but was not easy to install, without that 3rd arm from the center of your chest

If a CEL comes on, there needs to be a way to stop it. I believe it is getting too much air for the parameters of my mass air flow sensor. Sinister needs to either provide a MAF sensor with higher parameters or have access to a sensor to compensate for the increased air flow. I love the look of your product just disappointed

I am a cold air fanatic and the color is great

I do respect the 'somewhat effort' of the service department to fix the intake issue but I still have a check engine light on with either the dry or oiled filter. If I can find a MAF sensor that has higher air flow parameters your product would be awesome!

I live on a farm so I purchase this to help keep my air filter clean and it's doing the job just perfect and I couldn't ask for better, plus it looks cool.

So far so good... I have alot of electronics in my truck. Audio/video system, 3000 watt inverter, cell phone Booster, light bar, strobe lights, fuel transfer box and so on... So for me it wasnt just a purchase but more of an investment in the everyday operations of my work truck...

Does not fit as advertised. I had to drill a hole for the filter sensor and modify the bracket. Also was missing the o- ring and the wire harness wouldn't reach the intake sensor.

Product was supposedly designed to fit without modifications.

Only buy if you are able to modify this yourself.

Perfect fit and fast shipping. The metal tubing was perfectly bent and looks amazing. The fittings were also of the highest quality I have seen. Product will last forever as compared to the poorly engineered OEM rubber hose that fails after 60K.

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.
