New from 2025, including a vehicle report! The report only needs to be carried with you; no entry in the vehicle documents is necessary.

Our aluminum charge pipe replaces the OEM plastic pipes. In performance-tuned vehicles, the increased boost pressure can cause the original boost pipe to burst. In the worst case, the ingested debris can lead to engine damage.

The do88 pressure pipe has significantly better flow than the original, which we tested both in the car and on our own SuperFlow SF‑1020 flow test bench.

Advantages of the do88 charge pipe compared to the original pressure pipe:
• Flow at 0.075 bar pressure loss: 680 CFM (460 CFM), do88 48% more!
• Designed to withstand high pressure and high temperatures!
• The tube has two connections for methanol injection (1/8 – 27 NPT). These connections are supplied with blanking plugs.
• Plug & Play fits into the specified models!

The pressure tube was made from 3" extruded aluminum tubing and bent into shape using a mandrel bending machine. CNC-machined sensor flange for a perfect fit!

Specially developed, high-quality silicone hoses with displaced polyester/polyamide reinforcement to withstand high temperatures and high pressure.

The original pressure pipes and hoses were designed for the car's performance. If you increase the power and demand more from the car, they're no longer sufficient. That's why our pressure pipes offer the best performance and durability, even with higher boost pressure or software updates!

do88 pressure pipes are supplied with all parts necessary for assembly.

Items included in the pressure pipe kit:
1. Aluminum pressure pipe
2. Installation details for pressure pipes (without seal and without clamp – please take from the old pressure pipe)
