The K&N 57-1001 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some BMW 330 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your BMW’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-1001 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed past the mass air sensor and through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory vent hose. The oversized conical air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points. The tools needed are a screwdriver, socket set and a couple of wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

K&N 57-1001 Air Intake Product Reviews

Really cool air intake for the E46, installed it onto my 2005 330ci and it gave a nice sound. The car may not feel like it's got an increase in HP, it surely feels lighter when picking up so the torque gain is noticeable. Overall a good investment and a nice sounding product, would definitely recommend.

Great Kit Really happy with this K&N intake, super easy to install (and I'm no mechanic) Honestly didn't believe that I would be able to feel the difference, but boy was I wrong. Can really feel a difference in pull, at low & high RPMS. And obviously the sound is another thing, can really tell the difference between stock and this. Sounds quite viscous, Awesome sound and performance Also looks super clean in the engine bay. I was debating getting this kit, because the exchange rate made it more expensive for me. But honestly I wouldn't change a thing, you pay for what you get. And this kit is definitely worth every penny. Also shipping was crazy fast, I had my K&N intake in like 20 hours. Ordered, delivered and installed in less than 24 hours. This is my first K&N set up, and definitely won't be my last.

First time shopping with K&N, had a great experience and also got a good power gain from this product. I would recommend it to anyone looking for better sound and throttle response.

The plastic section would not fit inside the rubber hose from the engine as the instructions said so I had to use the original tubing which made it clear why the instructions say to save this piece. Also my dipstick is positioned further from engine block which made instillation a little more difficult.

When I went to purchase a cold air intake for my BMW 330xi i was not completely convinced that I would be able to REALLY hear and feel the difference... Boy was I wrong. I can absolutely hear the more throaty sound all the way through my exhaust and the increase in power is great! The installation was fast and easy. I definitely would (and do) recommend K&N to any and everyone that is looking for an easy simple way to increase their cars performance without breaking the bank. Thanks K&N -Satisfied Driver.

I ordered a K&N Cold Air Intake Kit for my 2002 BMW 330i. It was the easiest kit to install with help from great instructions I received. I immediately noticed a change in horse power and throttle response. I received the kit fast and was notified through the process. I have two other BMW's that I will be installing these kits on and will do for any other vehicle I have in the future. I recommend this upgrade to anyone with a vehicle period. Thanks K&N for your help!
