Rated 5 out of 5 by from Nice kit! Smooth install I was highly satisfied with the Roush X-Pipe I installed on my quad tip GT performance package so I had to grab this kit, glad I did. Looks fantastic, good fit, easy enough installation. You'll need a deep 10mm socket to reach nut holding the sound tube to firewall. I read online people tearing the sound tube out by just grabbing on it right at the bolt, I didn't have a deep well socket so I yanked and out came the tube, didn't have to remove the bolt, plugged the hole with the supplied plug. Crazy sound tube lol. Car sounds amazing at idle, excel and cruising. Love it thanks Roush for the stickers they look killer too..

Rated 5 out of 5 by from Fantastic Intake, Easy Install This is, by far, the easiest and best bolt-on modification to get for your 2018 Mustang GT. Absolutely beautiful construction and the fit is excellent! Easy-to-follow video guides even has-been gearheads (like me) easily and clearly. The difference is felt and heard immediately. If you're looking for a way for your Coyote to breath a lot better, don't settle for less!

Rated 5 out of 5 by from Looks Great Just recently installed on my 2018 Performance Pack GT. The factory Plastic 5.0 cover we took off because to trim the edge just looked 'rigged'. With the Tower strut Brace and other under hood mods it makes it look more professional. I also like the fact that I don't have to get a tune unless I want to. Eventually I will bit not just now.

Hello, How should the filter from the kit be maintained?

Asked by: dar_j
It should be cleaned and oiled about every 50,000 miles depending on the conditions. You will need a cleaning and oiling kit which will have instructions.

I purchased the intake before I saw the Roush Performance pack 1 available for sale. Is it possible to purchase the roush tune sepparately and have dealer install to get the 36,000 warrantee?

Asked by: Pdina77
We do not offer the voucher separately. Check with a participating dealer that can do the tune.

Asked by: Krackn
Unfortunately I cannot accurately answer your question. Without the vendor supplying any information regarding fitment for non-US Spec cars and CJ's not having a car to test parts on, we cannot confirm this part working on your vehicle at this time.

I would like to install a Roush cold air intake on my 2019 Mustang PP2.  Although a tune is not necessary, could you recommend one,  and what kind of HP increase can I expect. Thanks. Jim

I have a custom order 2019 GT being built an shipped to the U.K. and whilst I’m waiting for it to be put together, I’ll be getting parts in ready to install. I want to replace the intake straight away and I’m looking at this or the JLT any pros cons?

Asked by: Truman13
You cannot go wrong with either of those options.

Will the Roush Cold Air Intake Kit GT 2018 fit a 2019 Mustang GT without modifications.

Asked by: Nancyt
Ford has not made note of any major mechanical changes for the 2019 model year, so we would assume that most parts should bolt right up without any issues. But we have not personally had a 2019 at our facility to test parts on seeing as though they just started rolling off the assembly line and onto dealer lots in the past week or so.
