Turbo Inlet Hose, APR Motorsport, B5/B6 A4 1.8t Stock Replacement

Manufacturer: APR


After extensive testing we have found that the OEM compressor inlet hose is not rigid enough to prevent collapse during high boost situations where airflow to the turbo is most important. A collapsed hose creates a huge airflow restriction that robs your motor of potential power!  This is especially applicable on K04 turbo upgrades where the increased flow causes complete collapse of the stock rubber hose.

Engineers designed a replacement hose of high quality silicone with wire wrapping throughout to ensure no collapse at even the highest boost pressures. We found that simply recreating the hoses in silicone, no matter the density of the silicone, still allowed a collapse to occur. The wire wrapping ensures that not even the slightest collapse will be experienced providing more air to the turbo via the larger diameter of the hose and smoother transitions unleashing hidden power!

APR Motorsport Compressor Inlet Hoses are available in three colors; blue, black, and red. All APR Motorsport Hoses include everything you need for complete installation, including fittings and clamps.

Price per kit, we stock black hoses, color hoses can have a lead time.

Note: Some B6 1.8t applications will require an adaptation of the OEM breather system to fit the position of the breather inlet on this hose.

This hose was originally designed for the B5 application, the B6 is almost identical with the exception that the large breather port on the side of the hose comes in at a slightly different angle than B5.  If you are concerned please call or email us to discuss the extra parts you may need to make this adaptation, otherwise a typical auto part store should have the pieces to make this work.
