M52 upgrade intake manifold suitable for BMW 323i & 328i BAR-TEK®

Resurrect a classic and improve it in detail? That's exactly what we did! We were fed up with all the DIY solutions and all the different adapters for the M50 intake manifold. Constant leaks, broken adapters, glue that doesn't hold, who hasn't experienced it? But if you're looking for performance with the M52, there's usually no getting round a converted M50. Until now! We have breathed new life into the cast aluminium intake manifold from the 90s. And not only that. Small but subtle optimisations make our bridge even better than it already was and, above all, contemporary. No more annoying paper seals, but high-quality, long-lasting rubber seals. Our M52 intake manifold is completely cast in aluminium and then machined CNC. Channels are widened to the maximum, sealing surfaces are planned and grooves are milled. The plenum is then sealed with a billet CNC cover. We have also replaced the paper seal here. Features: up to 20% more power high-quality cast aluminium Machined in-house CNC for all M50 and M52 engines Billet CNC cover no more paper gaskets Our test drives in the 328i showed performance increases from to 231.6 hp with our intake manifold, manifold and customised software.
