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: Active 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 – 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.
NOTE: The factory exhaust catalysts MUST be removed in the process, making this solution recommended for off-road and racing applications ONLY.| BMW | E82 | 128i |

Brothers Mike and Karl Hugh were bred to play with power, it seems. As young men growing up on an island, doing things correctly for oneself became their ingrained credo. Their adolescent projects – bicycles and dirt bikes – were always the best performing. And that soon set the tone for the BMW tuning hobby they graduated to. By 1981, Mike and Karl were ready to get serious about their longstanding passion for a higher standard of BMW performance. Active Autowerke was born. Their motto at the time: "Anything and Everything BMW". They probably should have included “everyone” in there, too – since the endeavor was a classic family affair – with many branches of the Hugh family tree pooling their talents. The timing was ideal, and the company quickly grew as America’s motoring public developed a healthy appetite for the Bavarian treat. Soon Active Autowerke had grown into the largest independent BMW service center in Florida – with the most sophisticated equipment arsenal in the industry, certifications from leading componentry firms such as the Robert Bosch Corporation, and repute for setting the benchmark for service, integrity and professionalism.
