Created With Performance In Mind
As is the goal with building any header, the purpose of designing the N52 Performance Header was increase horsepower and improve overall performance. Our header does a tremendous job of freeing up untapped horsepower that the BMW N52 is capable of producing. After many dyno runs and recorded results, the data validates the Active Autowerke N52 Performance Header as must-have BMW performance part for a noticeable and powerful upgrade.
Material & Durability
Suitable for either naturally aspirated or supercharged applications, the N52 Header by Active Autowerke is made entirely of 100% 304 stainless steel. With this header, worrying about durability is a thing of the past.
Installation
Is installing the header difficult to do? Not at all! Robust exhaust flanges with recessed mounting holes make the installation of your N52 Performance Header a breeze. With a few quick turns of a ratchet, you will be well on your way to feeling the additional horsepower.
NOTE:u00a0Active Autowerke GUARANTEES that each and every N52 Performance Header will be a precise fit. Every Active Autowerke N52 Header is test-fitted on our N52 motor jig as part of our quality control.
Hardware:
As far as mounting hardware is concerned, this system is absolutely complete. The BMW N52 engine uses a single-use oval shape gasket to help seal the exhaust manifold against the exhaust port u2013 a floating design that also self-centers the exhaust flange as it is being torqued. Reuse of this gasket is NOT SUGGESTED which is why we provide you with SIX new gaskets as part of the installation hardware.
Also included are two fiber gaskets for where the header meets the remaining sections of the exhaust system. Copper locking nuts for the header to mount against the cylinder head and mounting bolts w/nuts to secure the header to the exhaust system are included as well.u00a0
NOTE:u00a0The factory exhaust catalysts MUST be removed in the process, making this solution recommended for off-road and racing applications ONLY. There will be a CEL without Active Autowerke software upgrade

PRIMA: A LEADER AMONG EQUALS

WHY THE PRIMA SUPERCHARGER KIT FOR YOUR E46 BMW M3?
Since BMW ceased production of the E46 BMW M3 in June 2006, it has become one of the most coveted models to enhance with various performance modifications. One of the more popular upgrades to date has been the addition of a supercharger system like PRIMA, capable of creating over 600 horsepower to the rear wheels.
As newer iterations of the M3 are introduced, past generations like the E46 invite a whole new community of BMW owners seeking performance modifications relative to the car’s value. This translates to reduced expense on Active Autowerke supercharger components, making it the perfect time for an entry level supercharger system.
Simply put, not much compares to a PRIMA-supercharged E46 M3 when it comes to bang for your performance-vehicle buck.
CAN I RUN PRIMA WITHOUT AN INTERCOOLER?
YES! In the past, running this kit without an intercooler would have been considered suicidal due to the extremely high 11.5:1 compression of the S54 engine. Thankfully, through years of product development, testing, and tuning of supercharger applications with this motor, PRIMA kit and associated software have undergone changes to successfully and safely marry the S54’s stock motor with the rigors of a boosted application.
WHY USE ACTIVE AUTOWERKE?
Guarantee Active Autowerke guarantees the quality of our BMW performance products; some of which surpass the performance industry standard. Combining a quality product with exceptional customer service are two of the core values we practice every day.
LongevityOur 30+ years of experience working and wrenching on BMWs is a true testament to what Active Autowerke is all about.
