ROUSH 422086 Cold Air Intake for 2018-2022 Mustang GT 5.0L

Easy installation. Good look. Throttle response a little better. Sound a little meaner. Watch out for the nut on the firewall when removing the OEM secondary air intake.

This kit was pretty easy to install other than the 10mm nut on the firewall holding the sound tube. I think it took me about 2 hours from start to finish. Fitment is great other than you cant use your engine anymore unless you modify it. Sound didnt really change much. Performance was very noticeable but i did pair it with a BAMA tunes 91 octane performance tune. The dyno results i have seen on a stock 5.0 with the roush and a 93 octane tune have been a 30ish hp bump, i dont think i gained that much but it’s definitely in the 20-30 hp gain range. Low end power gains were noticeable as well as the upper end of the rpms.

Great product comes with all bolts needed for install along with inner sleeve for tuned vehicles

This worked great! I decided not to cut, and this is what it came out to look like. I like it! Looks cleaner to me. I’ll just take the engine cover off when I need to change the filter, takes two seconds. Hope this helps!

This Roush Performance CAI was very easy to intall once the facotry system was removed. I dropped one star for two reasons:First, they could have provided paper instructions in the box, or at the very least the template for trimming the engine cover. You have to download them and print the template. Which took me a couple tries to get the scale correct on the template. Take your time cutting the engine cover if you want a clean, professional install.Second, it could have some rubber seals, or at least tighter fitting parts where the intake tube connects to the airbox.There was also a scuff on the clear section of the lid. I'm sure I can polish it out with headlight lens polish. Would be nice if a blue colored filter was an option.Overall, even without a custom tune, there was a noticeable increase in throttle response.

Increased my low end torque and that increased the local drive mileage per gallon by a little over a mile per gallon. No ECU re-programming done as I would loose the warranty my new GT Tang. I got it installed at the dealer ship. Recovered my money in about six months after install. Its been 15 K miles already after the install and the cold air intake works great.

Pretty easy to install. The one issue I had was removing the 1 screw from the firewall. That was a bit challenging.

It definitely increases throttle response and looks good when you pop the hood.
