BMW X5 E70 Cold Air Intake | Unlock Power with BMW N55 Performance Intakes
If you’re looking to boost your BMW X5 E70’s performance, there's one mod you shouldn’t overlook — a cold air intake. Whether you're driving the turbocharged BMW N55 engine or upgrading from the factory airbox, a performance intake is one of the easiest and most effective ways to improve power, throttle response, and engine sound.
At BimmerHaus Performance, we specialize in high-quality BMW intake systems that are engineered for enthusiasts who expect results.
Why Upgrade to a BMW X5 E70 Cold Air Intake?
The factory intake system in your BMW X5 E70 is designed more for emissions and cost efficiency than performance. A cold air intake replaces the restrictive OEM setup with a high-flow filter and smooth piping that draws in cooler, denser air from outside the engine bay.
Key Benefits:
- Increased horsepower & torque
- Enhanced throttle response
- Improved turbo spool time (N55 engine)
- Aggressive engine sound under acceleration
- Better airflow efficiency
BMW N55 Intake: The Heart of Turbo Performance
The BMW N55 engine — found in many X5 E70 models — is a single turbo inline-6 that responds exceptionally well to intake upgrades. A performance intake allows your turbo to breathe easier, reducing lag and improving efficiency.
With a BMW N55 intake, expect:
- Cooler intake temperatures
- Smoother airflow to the turbo
- Noticeable bump in mid-range power
- Increased blow-off valve sound (if equipped)

What Makes a Great BMW Performance Intake?
Not all intakes are created equal. At BimmerHaus Performance, we focus on:
- Mandrel-bent aluminum or silicone piping
- High-flow, washable cone filters
- Heat shielding or relocation for cold air induction
- Bolt-on installation with no tuning required (optional for max gains)
A true BMW performance intake delivers results without compromising engine safety or drivability.
FAQs About BMW X5 E70 & N55 Cold Air Intakes
Is a tune required after installing a performance intake?
Not necessarily. Most intakes are plug-and-play, but pairing with a tune can maximize gains.
How much horsepower can I gain with a cold air intake?
We did before and after dyno's and showed gains of 40 ft lbs of torque and 20 hp! These gains are realistic with a quality system that includes a high flow inlet. You can find that video here.
Does a performance intake void my warranty?
We have all heard the stories... something happens to the motor and a claim is denied because you have after market wheels. The bottom line is warranty companies are not in the business of approving claims - that is not how they make money. While these intakes will not adversely affect your vehicle, we recommend keeping your OEM parts so you can go back to stock when and if needed.
Will it improve fuel economy?
Potentially. A more efficient intake may offer slight MPG gains, especially under light throttle.
Is the BMW X5 E70 intake install DIY-friendly?
Install requires sufficient mechanical ability as you'll be accessing the area in and around the turbo. We offer support for those who want to do DIY installs, and have many videos online. If you are not comfortable, professional install is recommended.
Final Thoughts
If you're serious about enhancing your BMW X5 E70's performance, upgrading to a BMW N55 cold air intake is a no-brainer. It’s the perfect first mod that brings real results in power, sound, and engine efficiency.
Whether you’re looking for throttle response or track-day gains, BimmerHaus Performance has the parts and knowledge to help you push your build further.
