The best intercooler pipe kit for BMW 135i 335i 35i N54 (E90 E91 E92 E93 E82 E88) on the market!

The DO88 pressure hose has noticeably better airflow than the stock hose. This has been verified in several tests, both in the car and in our SuperFlow SF-1020 flow bench.

Significant advantages with do88 pressure hoses (OEM hoses):
– Airflow at 0.1bar/1.45psi pressure drop: 737 CFM (542 CFM), do88 36% more! See diagram below.
– Designed to handle high pressures and temperatures!
– The hose has two connections for methanol injection (1/8 -27 NPT). The hose is supplied with blanking caps in these connections.

Pressure tube is made of 3"" mandrel-bent seamless aluminum. CNC machined sensor flange for best fitment.

High quality custom made silicone hose with 4 layers of polyester/aramid reinforcement. These hoses can withstand very high temperatures and pressures!

The OEM intercooler pipes were designed for the power level the car was built for: an increase in power or even very hard use of the car in a standard version can cause the OEM pipes not to have the performance you need. Only after adjusting the engine software will the do88 pressure hoses give an increase in performance compared to the OEM hoses!

do88 pressure hoses are supplied with all hardware necessary for installation.
