Turner Motorsport offers a variety of Performance Intake options for your BMW, including Genuine BMW, aFe Eventuri, Dinan, Gruppe M, Agency Power, and ECS Tuning.
The BMW G20 B58 Eventuri intake has been developed to provide the turbo with a less restrictive flow path whilst maintaining low inlet temperatures. Heat and Volume are the main considerations when designing an intake for turbocharged engines. In the G20, the intake system is located next to the exhaust manifold which rapidly heat soaks the engine bay. High temperatures are detrimental for engine performance as the turbo would have to build boost with heated, less dense air and so the only way to ensure IAT’s are kept to a minimum is for a fully sealed intake. This however, results in a restriction with only one stock air feed to draw air in from. During development, the folks at Eventuri noticed an additional opening into the wheel arch area and took advantage of this by adding a secondary feed to our airbox. Furthermore, the sealed airbox also has a heat shield with gold reflective to minimise the radiative heat transfer from the exhaust manifold. In order to maximize volume, they made the airbox as large as possible with a recess for potential strut braces. The stock convoluted intake tube is replaced with a smooth carbon tube which is also larger in internal volume with a starting internal diameter of 111mm (4.4') smoothly tapering down to match the turbo inlet. The tube provides a smooth path from the filter to the turbo inlet. Finally, they use a custom-made high-flow dry filter that is ISO tested for filtration performance and has a larger filtration area than the stock filter.

AutoTecknic was established in 2000 and has since become one of the largest manufacturers and distributors of carbon fiber parts and accessories for a wide variety of manufacturers. AutoTecknic's Dry Carbon Cooling Plate provides the G22/G23/G26 4-Series with better air induction while providing the intake and engine with cooler air during high-speed driving. It also gives your engine bay a fresh appearance. Dry carbon fiber's name also comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold, and then into a sealed vacuum (autoclave) to properly cure. This particular method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The autoclave vacuuming process of making dry carbon means that there are fewer pinholes and virtually no air pockets that form in the carbon. Dry carbon is the highest quality version of carbon fiber products that are produced.
