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

Easy to install

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

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.

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.

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.

I had to make hole for sensor as u can se i drilled it out,snd very disappointed one of two pre drill holes to hold filter to hold filter inside box was stripped out bolt would not tighten up "stripped out" plus what i wrote be one of roushes mufflers was dented damaged im still not sure if im gonna keep i should return it......

One of the best intakes out there. Nice gain while keeping intake temps down. Super easy install.

Easy to install and gainful horsepower on our 21 5.0 Mustang. Better throttle response.;)
