If you're looking to boost your BMW's performance, you've got to check out this 7-inch tall "Oil Free" Air Filter. This isn't just any filter; it's a conical, 360-degree radial flow design that brings in maximum airflow thanks to its three layers of synthetic media. Trust me, once you get this in your ride, you'll feel the difference. It really helps unleash that turbocharged B58 engine.

Now, let???s talk about the high-quality intake tube. This isn???t some generic part; it???s dyno-tuned to squeeze out every bit of power while fitting like a glove. You won???t have to worry about any awkward gaps or misalignments. Just smooth, seamless installation that keeps your engine looking sharp.

And then there???s the lightweight vacuum form plastic cover. It gives your engine bay a clean, stealthy look while cutting down on intake noise. You can even plug the auxiliary air inlet if you want to keep things quiet. But don't worry, it won???t choke your power???this setup is all about performance.

Installation? Easy peasy. Everything you need comes in the box???clamps, couplings, and hardware. It???s a direct bolt-on kit, so you won???t need to break out the saw or drill. Just a few tools and you???re good to go.

Keep in mind, though, this product isn???t CARB exempt, so if you're in California or have a vehicle registered there, you might want to look elsewhere.

  • 400 CFM Rating at 7" H2O???that???s some serious airflow.
  • Expect gains of about +9 HP and +10 lbs. x ft. of torque. That???s not just numbers; it???s the kind of power you can feel.
  • This system outflows the factory intake, no contest.
  • It features a CAD-designed roto-molded intake tube for that perfect airflow.
  • The Pro DRY S oil-free 3-layer synthetic media means you get excellent filtration without the hassle of oiling.
  • No cutting or drilling required, which means a faster, cleaner install.
