The intake manifold takes incoming air from the intake and distributes it to each cylinder. Over the years the manifolds have gotten more sophisticated and complex. Most of the additional work that it does is emissions-related - recirculating vapors back into the engine to be re-used. But there are also performance innovations such as BMW's DISA variable intake runners. All of the modern innovations have a part behind it and here you will find replacement components.
In some BMW models there are performance improvements with intake manifolds. These intake manifold upgrades use mostly BMW parts and are a direct replacement for your stock manifold. We offer manifolds and kits to make the conversion work easier.
Vargas Turbo has released their very own BMW B58 vacuum/boost adapter. These go inline with the intake manifold fitting and provide a full boost/vacuum signal from the manifold. This fitting adds two 1/8" NPT bungs to accept any fitting that has 1/8" NPT threads. You can choose three configuration options: Fitting by itself Fitting with one 1/4" barb and one plug Fitting with two 1/4" barbs Once installed it tucks perfectly under your engine cover. These are perfect for running your PI switch off manifold pressure, which is much more accurate than the charge pipe, and they are also great for BOVs running the proper size line without having to drill a hole in your manifold. These do space out any sensors etc giving inaccurate readings like some of the other brands do.

This 2000hp-capable port injection intake manifold with integrated high-density intercooler core will take your Gen2 B58 build to the next level! When it comes to intake manifolds, it doesn't get any better than this. The Fuel-It! intake manifold replaces your weak factory plastic B58 manifold with a direct-fit, high-flow, high-strength billet aluminum manifold. Features a huge intercooler core capable of supporting up to 2000hp, port injection bungs located on the top of the manifold for easy access and optimal injector spray pattern, and 1/8" expansion ports perfect for direct port nitrous, water/methanol, or anything else you can imagine! Includes high-quality o-rings and all required hardware. Available with required port injection hardware (calibrated injectors with plug-and-play fuel line), or à la carte without the extra fueling hardware. The optional high-quality Bosch EV14 42mm fuel injectors are offered in 550cc, 750cc, and 950cc options.
