DESCRIPTION
Upgrade charge-air cooling with the do88 BigPack Intercooler Kit. BIG-270-S fits BMW 135i/335i/35i N54 (E9X/E8X) 07‑10.
The best BMW 135/335 E9x/E8x N54 performance intercooler and pipe kit on the market!
This comprehensive package includes both our do88 performance intercooler and charge pipe kit, delivering unmatched performance and reliability. Tailored for high horsepower builds, this kit ensures optimal airflow and cooling.
Upgrading just the intercooler already brings significant improvements, but combining it with our charge pipe kit yields even greater results. Our pressure pipes offer superior airflow compared to stock piping, improving reliability over time. Even on non-modified cars, the stock plastic pipe is prone to failure, making this kit an essential upgrade.
Advantages with do88 BigPack (vs OE intercooler/pipes):
- Greater core volume: 15,517 cm³ (OE: 6,933 cm³), 124% larger.
- Larger frontal cooling area: 1,151 cm² (OE: 658 cm²), 75% larger.
- Airflow at 0.15 bar / 2.18 psi pressure drop: 498 CFM (OE: 354 CFM), 41% higher.
- Peak power gain: 13 hp (measured on 335xi N55 with Stage 1 tune).
- Lower post-intercooler air temperature: 43°C (OE: 58°C), 15°C lower (measured on 335xi N55 stock except intercooler).
- Designed to handle high pressure and temperatures.
- Charge pipe features two methanol injection connections (1/8"-27 NPT) with included blanking plugs.
The BigPack includes the full aluminum do88 performance intercooler and a complete 3” (76 mm) throttle-body side charge pipe kit with silicone hoses. This kit replaces everything from the intercooler inlet to the throttle body, drastically improving airflow and cooling performance.
The intercooler is all-aluminum with CAD-designed, flow-optimized cast end tanks and an optimized core. The charge pipes are 3” mandrel-bent seamless aluminum with CNC-machined throttle body flange. High-quality silicone hoses feature 4 layers of polyester/aramid reinforcement for extreme temperature and pressure resistance.
OE intercoolers and pipes were designed for the stock power levels. After tuning or intense use, OE parts may be exceeded. The do88 BigPack unlocks the true performance potential of your vehicle.
All necessary hardware is included for a hassle-free installation.
