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% on the driver-side intake tract and 22.8% 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 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.

Good
Size: X-Large, Color: Riviera Blue, Size: X-Large, Color: Riviera Blue
I got XL which is my normal size. It’s a bit roomy which I think is exactly what I wanted for a work shirt. I wanted it to be a no tuck shirt, but it’s too long for that. I’m really disappointed there, but it’s not a dealbreaker. The sleeves are a bit long, but my arms are short, so I will modify it or roll them up, not an uncommon problem for me with shirts but it’s not too bad either. The material is soft and would be good for summer or under a jacket. Someone posted about the collar being messy and that made me nervous to get this shirt, but I have washed it once and the collar remains in good shape. It stands up properly. The wrinkleproof seems to be pretty good.

Good shirt
Size: X-Large, Color: Bel Air Blue
This is a good shirt, I’m 5’ 9” and 220 (old dad bod 50’s), it fits well and the sleeves are a good length. My only thing I don’t like and this is nit-picking: it wrinkles easy. I’m ex military so I like my shirts ironed or pressed, I get it it’s more casual, it’s just my preference. This is a comfortable shirt
