One design challenge for this B58 Intake system is the location, it is just next to the exhaust manifold which rapidly heat soaks this position in the engine bay.\u003c\/p\u003e\u003cp\u003eHigh air intake temperatures are terrible for the engine performance as the turbo would have to build boost with hot, less dense air. This is why a fully sealed intake system is the only way to go to ensure IAT’s are kept to a minimum. To eliminate hot air from being drawn into the air filter we designed a heat shield and lid that together with rubber sealings makes our system feed the engine with nice cold air. Our intake system uses the OE fresh air inlet duct that feeds the air filter with fresh air.\u003cbr\u003e\u003cbr\u003eAs replacement to the OE plastic intake pipe, we designed a large 85mm (3,3”) mandrel bent aluminum pipe which expands to 93mm (3,7”) towards to the turbo inlet elbow. We didn’t take any shortcuts when we designed the inlet pipe, we sourced the unusual size of 85mm to get the correct inner diameter for the MAF-sensor. Many competitors sell kits with 89mm (3,5”) inlet pipes which is easy to source. But the danger with 89mm pipe is that the MAF-reading will be wrong and therefor causing the fuel mixture to be lean. It is not uncommon to get CEL (Check Engine Light) with such setup. Fitted to our intake pipe is a large custom-designed air filter. The filter has a densely knitted cotton gauze for superior filtration. The filter is of course washable and reusable for optimum performance and long service life.\u003cbr\u003e\u003cbr\u003eThe original air filter box and turbo inlet hose are designed with elements that minimize the noise produced by the turbo and the air induction. Specifically, the factory intake hose features a large sound silencer to ensure the turbo operates quietly. In contrast, our intake system comes without these noise-reducing elements, allowing you to hear turbo spool and induction sound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLarge 85mm (3,3”) custom-designed cotton air filter with densely knitted cotton gauze. The filter is delivered without any filter oil applied therefore we recommend that the air filter is applied with cotton filter oil to increase air filtration if you drive your car in any dusty environments.
