This BigPack replaces everything between the turbo outlet and the throttle body with a do88 performance intercooler and a complete 2.5 in pressure pipe kit. The all aluminium intercooler holds 9,677 cm³ of core volume against 3,672 cm³ for the plastic tank OEM unit, 163% more, and uses cast, flow optimized end tanks that cope with higher boost than the factory plastic tanks. On do88's SuperFlow SF-1020 bench the BigPack flows 275 CFM at a 0.15 bar (2.18 psi) pressure drop against 244 CFM stock, 13% higher, and post intercooler air measures 38°C against 69°C, a 31°C reduction. The mandrel bent seamless aluminium pipe is joined by three custom silicone hoses with four layers of polyester and aramid reinforcement, here in blue. do88 notes that a power increase over the OEM intercooler comes only once the engine software is tuned.
