ROUSH 421826

Great part for the car. Easy to install.

Exactly how it was described. Perfect fit no problems

Fits perfectly! Removing the noise tube into the cabin was the toughest thing involved with the installation. To remove the 1 nut on the firewall behind the engine holding the noise tube in place took close to 2 hours of: sweat, pain and a little blood. But was way worth it, for the fit and finish of a pro shop. If you happen to have a small child at home or .... near by... use the child to get to the bolt as the child's arms my actually fit, TOP HINT: remember to use a fender cover so your belt, or small child does not scratch the paint! I found the best way to gain access to the bolt was to squeeze my arm in right near where the oil dip stick is located, using a very small wrench as a socket wrench will not work as the welded bolt is far to long for any socket to fit over.

OK my only gripe is that clips that hold the seal to the top of the cold air box are way to small for the holes and don't hold the foam rubber seal properly. I used gorilla glue to fix the issue and insure the red clips don't come loose. Very disappointed to have to do this for the price of this cold air intake. Makes me wonder if this is true Roush quality and what is going on with this product? It is listed as Roush and New on the website but since I picked the seller that was $415 verses $449 it makes me wonder...... Other than that the car sounds great now, better intake growl, and getting rid of the factory sound tube really cleaned up the engine bay and no more fake intake noise being pumped into the cabin from under the dash and the 10 hp bump in performance is nice as well on my 2016 Mustang 5.0 convertible.

I replaced the K&N alternative two weeks after install and was totally worth it! The Roush costs about $10 more and takes an additional 10-20 minutes to install, but again TOTALLY WORTH IT! The air box is much more solid than the K&N, not to mention it's more than twice the size, along with the air filter! Also, by completely removing the resonator all the way to the firewall (as opposed to capping off the tube) you get a much cleaner more professional look! As for performance, that's the reason I even wanted to see what the Roush had to offer. I was very disappointed in the K&N off the line performance, way too much hesitation. With the Roush, the tires light up every time I want them to! Trust me, I spent the extra $360 to try both the K&N and the Roush and I can promise you, you will not be disappointed if you know what you're doing!
