BMW B48 B46 B58 Front Mount Intercooler Upgrade for 2016 – 2019 BMW M140i/M240i/340i/440i & xDrive

Free Shipping

Replace your stock front-mounted intercooler with the Norcal Dynamics Competition HD intercooler upgrade kit to unlock maximum performance and reliability for your M240i, 340i, and 440i equipped with the B58 engine. Designed to be one of the highest performing, direct bolt-on intercoolers available for your BMW, this kit emphasizes quality and performance while maintaining an affordable price. Our intercoolers deliver significant horsepower gains by keeping intake temperatures low and preventing heat soak, a common issue with the factory intercooler. The result is more power, enhanced reliability, and a reduced likelihood of pre-detonation and engine knock.

The core is the most crucial component of any intercooler. It cools the charged air from the turbo before it enters the engine. The stock BMW tube and fin intercooler is built to support low boost levels and airflow, but when boost levels and airflow are increased, the OEM unit is easily overwhelmed and struggles to meet the cooling demands of a tuned engine running above stock boost levels. This leads to heat soak, resulting in power loss and a higher chance of pre-detonation at higher RPMs.

Each Norcal Dynamics product comes with a lifetime warranty and our "No Hassle" satisfaction guarantee, covering fitment and defects. Our intercoolers are hand-finished and pressure tested to ensure a high-quality, leak-free experience.

FAQs

1. Will this intercooler work with my BMW B58-equipped model?
Absolutely. This B58 intercooler is a perfect fit for 2016-2019 BMWs with the B58, B48, or B46 engine. That includes the M140i, M240i, 340i, and 440i, in both rear-wheel and drive versions. Just confirm your car's exact year and model for a guaranteed fit.

2. What performance gains or benefits can I expect after installing this B58 intercooler?
You will see more reliable power. This B58 intercooler drastically cuts down intake air temperature. Fighting heat soak helps your engine hold onto its horsepower and torque, even during back-to-back pulls or on a hot summer day. It's a key upgrade for any tune.

3. Is the installation bolt-on or will I need modifications or tuning?
The install is a straightforward bolt-on affair. Our B58 intercooler uses every single one of the factory mounting points. That means you won't need to cut or modify anything. While a tune isn't required to run it, getting one will let you fully unlock its performance potential.

4. Is this intercooler compatible with other charge pipes or aftermarket intake systems?
Yes, it works well with other parts. This front-mount B58 intercooler is made to be compatible with your stock intake or a new aftermarket one. It also connects without a problem to your factory charge pipes or any aftermarket charge pipe upgrades you might already have.

5. Does the warranty or guarantee cover failures due to high boost or tuning beyond stock?
The warranty protects you from any manufacturing defects or workmanship issues. However, it does not cover damage that happens because of a bad install, running too much boost, or using a tune that pushes the engine far beyond its stock power levels. Drive responsibly.
