This is do88's fully sealed intake system for the B58 Gen 2 supplied with the CNC-machined do88 turbo inlet for the original turbocharger. A 7 inch sealed airbox with its own heat shield and a secondary air feed keeps intake air temperatures down next to the exhaust manifold, and a carbon intake tube starts at 105mm (4.1 in) before tapering into the turbo inlet. The turbo inlet adds an 89mm (3.5 in) hose connection with a flow optimised radius that removes the last restriction ahead of the compressor. On do88's SuperFlow SF1020 flow bench the intake alone measures 15% more airflow, rising to 23% with this turbo inlet fitted. The densely knitted cotton gauze filter is washable and reusable, and the system omits the two factory sound silencers so turbo spool is audible.
