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 rotational-molded thermoplastic 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 thermoplastic material ensures the air intake system will incur minimum engine bay heat soak and provides unmatched durability for years of service in the harshest environments. 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 performance intake kit includes our signature Mishimoto Lifetime Warranty.

Quite good. I am actually surprised. Too small for queensize
Item Package Quantity: 2, Size: Queen
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning. Update 04/24 These are actually quite small to be considered queen pillows. They have become firm over the last few days.

Full, Fluffy & Perfectly Supportive Euro Pillows!
Item Package Quantity: 2, Size: European, Item Package Quantity: 2, Size: European
These Euro size pillow inserts are fantastic! They’re soft, full, fluffy, and hold their shape very well. The firmness is perfect — supportive without feeling too hard. They filled my pillow covers beautifully and made the bed look much more luxurious. Great quality for the price and very comfortable for lounging or sleeping. Very happy with this purchase!

amazing.
Item Package Quantity: 4, Size: Queen
WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!

These are very thick pillows.
Item Package Quantity: 2, Size: Queen
Exactly as advertised. They are very firm and very thick. They're too thick for me to be able to use as bed pillows. However, they seem to work pretty well as cushions in my papasan chair on top of its normal cushion also work very well as decorative pillows. I'm still giving them four stars because they're exactly as advertised and they seem well made. My only complaint is that they're just too thick. And that's definitely not the fault of the pillows or the pillow maker.
