      Description

      The M3 has undergone significant evolution over the years, with each new iteration bringing something new to the table. From the brilliant widebody E30 of the eighties to the exotic sounding V8-powered E9X, each generation has its own identity but holds true to the goals of providing an amazing driving experience. The G8X gets one of the most potent engines produced by BMW to date, the S58B30, along with an option for AWD. Enhancing the S58 was something we set our sights on soon after acquiring a G80 of our own, the first project being our air intake system. Airbox volume, shape, and construction material all play a part in delivering maximum airflow to your engine. Our engineering team created extremely precise carbon fiber airboxes that eliminate restrictions, supply maximum cool-air entry via two additional ports that open to the wheel wells, and improve engine bay aesthetics. The use of carbon fiber material ensures the air intake system will incur minimum engine bay heat soak and provides unmatched aesthetic appeal. Our airboxes were designed using the latest in 3D printing, CAD modeling, and flow bench technology. As a result, we reduced air intake restriction by 13 percent on the driver-side intake tract and 22.8 percent on the passenger-side intake tract. For proper filtration, this kit includes dual high-flow oiled air filters which provide improved filter surface area and improved airflow over the stock panel filters. In addition to the flow benefits, our intake system provides a significant amplification of turbocharger spool and bypass valve venting. These enhanced sounds provide a new level of enjoyment, adding to the incredible driving experience you expect from a BMW M-Series. The Mishimoto 2021+ BMW G8X M2/M3/M4 Performance Intake is a complete bolt-on kit and includes all necessary components for an easy installation. As with all Mishimoto products, this carbon fiber performance intake kit includes our signature Mishimoto Lifetime Warranty.

      Air intake systems are a common first mod to many project cars. They are quick and simple to install while also enhancing the looks of your engine bay, the sounds of your engine, and the performance of your vehicle.

      We often recommend upgrading your OEM intake to a cold air intake as one of the first modification your should do to your car. Often times, the factory airbox is restricting. Replacing your intake system with an aftermarket unit will increase intake noise, performance, and improve your overall driving experience.

      Mishimoto, the world leader in performance cooling products, was created for automotive enthusiasts by automotive enthusiasts. Established in 2005, we have more than a decade of experience in working toward our goal of providing superior cooling system upgrades for sport compact, modern muscle, European performance, classics, Jeeps, and trucks.

      Turbo Sounds!

      This things sounds like a jet when you put your foot into it. I dont have the top on so it may be louder for me than those that do, but the sound of the turbo coming through intake is something else.

      Sounds & looks amazing!

      I was skeptical about installing a cold air intake after reading mixed reviews. However, this unit just looked so good I wanted it for pure aesthetics even if the performance was not enhancing to my 2.0 turbo. When I first installed it I did get a check engine light, but I think that’s because I didn’t disconnect the battery first. But after a couple drives the light went away and it sounds super awesome! I totally feel like it added a bit of pep and when the head is up it looks absolutely amazing. I love this product! The only difficulty in installing is trying to get the valve off using the included clip tools (you’ll know what I mean lol). But, I just disconnected it from the car which gave me better access to the tabs.

      Mishi CAI reigns supreme

      Coupled with a C&L bypass valve adapter during installation and my turbo has been brought to life. This thing is nasty. I liked the looks of other CAI’s better but the reviews on the mishimoto sold me and did not disappoint. I love the sound of this intake. I’m a bit of noob with doing work on cars so it took me about 2.5 hours on the install. Seems like I really struggle with the connections, and I’m very cautious about making sure everything is perfect. Only problem I had was the connection to the ground wire gave a bad ground and the brake light and hood ajar light came on, so I had to scrape off some of the paint on that portion of the box that connects to the ground wire and problem solved.

      Best looking air intake

      This intake sounds amazing when you rev the motor and looks way better than the other intakes out there. Plus, who wants to add more black plastic to their engine bay? Not me

      Perfect Turbo Sound

      Finally this car sounds like a turbo car! Materials quality is excellent, looks great, sounds perfect. Really an exact first mod. Not sure I need an exhaust upgrade after installing this because all I think about is the turbo now. Also was planning a blow off valve, but this alone sounds so great, it might not be needed! Be careful to ensure the harness grounding strap is still in electrical contact with the frame of the car or the left headlight won't work, the hood ajar light and parking brake lights will be stuck on, the front radar if equipped will fault, and some alerts related to these will pop up. Once grounded properly they all disappear, no long term harm done. Install is not too hard but probably is easier in warmer weather for working the connectors near the turbo on and off. I think 1.5 hours.
