Description

The 2018-2021 Mustang 5.0L V8 Cold Air Kit is more efficient air intake than the standard stock airbox. Cold air induction allows for latent potential in power and fuel efficiency that would otherwise be restricted, as well as providing reduced pressure drop. A custom tune is not required as this CAI system was engineered and tested specifically for this application, ensuring MAF signal performance matches factory settings. Included is an innovative airbox lid with see-through lens. The dry filter is proven to retain its shape under high airflow, and is composed of an inner and outer layer of wire mesh for durability and reliable support of filtration media. The filter requires no oiling and is easily washable for re-use. Included in the kit is the air filter with clamp, injection-molded lower airbox/tray with installed EPDM foam hood seal, blow-molded clean air tubes, and all required mounting hardware. The kit utilizes all factory emissions and vacuum lines. Factory mounting locations and hardware are utilized to allow for quick and easy installation. This Cold Air Intake Kit fits 2018-2021 Mustang GT 5.0L.

  • Exactly as advertised
bought this for my dad as a christmas gift and he loves it!! easy to install. fit perfectly with the exception of having to cut part of the engine cover, which was easy to do. 10/10 would recommend.

  • Nice Gains
This is a great upgrade to my mustang! The instructions were a little difficult to follow and there is some cutting required but it looks good and performs well.

  • Good value intake system
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. ... show more

  • This is the best looking option for the 2018 gt
This is the best looking option for the 2018 gt. Simple installation and does not require a tune. A cap is provided to plug the hole left in the firewall after deleting the sound tube. I dig the way the engine bay looks without the engine cover but you will need to trim the driver side with the provided template if you choose to reinstall. Mine shipped with only one W500224 (used to secure the tube to the housing) and an extra W506976-S437 for the lid. ... show more

  • Needs insulation information
Should come with instructions. It’s kind of a pain to put in, but it is awesome.

  • Great product
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. ... show more
