VRSF Street HD Intercooler FMIC Upgrade Kit 10-18 BMW X3 35iX, X4 35iX & X4 M40iX F25 F26 N55
VRSF Intercooler Upgrade Kit
for your 2010 – 2018 BMW X3 35iX, X4 35iX & X4 M40iX F25 F26 with the N55 engine.
Replace your inefficient factory intercooler with a VRSF upgraded intercooler kit to get the most out of your N55. Our intercoolers are designed to be the best performing, direct bolt on intercoolers available for your BMW with special attention to quality and performance while maintaining a reasonable price. Each VRSF intercooler includes our proprietary High Density fin pack which results in higher HP gains compared to the other guys, mainly due to our incredibly dense internal and external fin pack. Our core was engineered to offer a greater overall surface area for increased heat absorption as well as dissipation.
VRSF HD Intercooler Core
The most important component of any intercooler is the core. The core cools the charged air from the turbo before it enters the engine and the OEM BMW tube and fin intercooler is designed to support low boost levels and air flow. When tuned, airflow and boost levels are increased significantly. This causes the OEM intercooler to heat soak and reduces HP and increases the chance of pre-detonation.
We remedy this problem with our proprietary, high density bar and plate intercooler core which utilizes a staggered and offset internal and external fin pack. The VRSF HD core has been carefully balanced to provide the the best intake temperature reduction while maintaining minimal pressure drop. The VRSF HD core is also much more durable than the OEM tube and fin core, with a better ability to withstand rocks and other debris.
The VRSF Performance HD Intercooler is comprised of an incredibly dense fin pack both internally and externally. It’s not uncommon to see intake temperatures drop at the end of a 3rd gear pull due to the Performance HD’s larger overall surface area. You can expect to see an intake temperature reduction on a stock turbo, full bolt on car during a 3rd gear pull which is why we the Performance HD is THE best option for your N55. Please note that the HD fin pack is now standard at no extra charge!
Installation & Construction
We include everything required to replace the OEM intercooler on your X3 35iX, X4 35iX & X4 M40iX.

We are typically very quick and have a 24-48 hour turnaround time. Transit time depends on your order and which warehouse we are shipping from, but typical transit times are between 5-7 business days from one side of the US to the other.
Majority of the items we offer do ship free to the lower contiguous 48 states. States that require plane or boat to reach (such as Hawaii, Alaska, Puerto Rico, etc) do NOT qualify for free shipping. Please contact us to inquire about international shipping costs. During checkout, you will know which items ship free and which have shipping costs associated with them. In general, larger/heavier items will have additional shipping costs (body kits, wheels/rims, etc)
Even though everything can be shipped internationally, sometimes the cost is simply just too high and doesn't make sense to do so. We're here to make sure you have a great shopping experience, so if you have a product(s) you want to inquire about, please contact us at email@example.com
