The APR Boost Tap for the 1.8T and 2.0T EA888 Gen 3 engines is a simple, yet elegant solution for referencing boost pressure and vacuum as is commonly necessary for boost gauges.  The boost tap plugs into an unused port on the factory intake manifold and doesn€™t interfere with the factory T-MAP sensor.

Traditionally boost is tapped by spacing out the factory T-MAP sensor on top of the intake manifold.  However, APR€™s engineers discovered using this location lead to inconsistencies in intake air temperature readings and potentially a loss of power.  Upon this discovery, APR€™s engineering team went back to the drawing board and came up with a new and unique solution.

Utilizing the included punch tool on a warm engine, a boost and vacuum reference port is easily spread opened on the factory intake manifold.  The billet aluminum boost tap then connects to the port and uses dual Viton o-ring seals for leak free operation.  The reference hoses connect to the rear of the tap via a barbed stainless steel connection point and conveniently routes through the engine bay.

In addition to the boost tap, APR provides several extra components to help suit each individual€™s needs.  For those requiring more than one reference source, a T-fitting allows for more tapping points.  In the case where a mechanical boost gauge is used, the brass restrictor pill limits flow and cures gauge buzz.  Just less than 100 inches of 200 PSI hose is included with OEM style ear clamps and black cable ties to allow for neatly routing hose through the engine bay.

Your tuner and engine will thank you for this part. Reliable and accurate boost tap.


Best boost tap

I was running a different boost tap and a buddy pointed out that the map sensor being spaced out was most likely causing improper readings of IAT’s and a possible loss of power. After installing the APR boost tap I noticed my IAT’s were closer to ambient temperatures and would actually dip when blipping the throttle and the car as expected in driving in cooler temps. Very much worth the purchase.

Easy to install

The boost tap is great! Install was easy, and the quality was top notch as to be expected from APR.

Chance Y.

Only one worth buying.

There is not a single other boost tap worthing buying! Make sure to drive the car around for 15-30 minutes before tapping the manifold for the boost sensor.


Sweet and simple

This apr boost tap is awesome for running my hks ssqv4 on my mk7 Gti. I will also be using the t to add an aem boost gauge soon. Super easy install and like that the instructions are a pdf which saves paper from being wasted. Hands down a great product sold by a great company bmptuning. would give more then 5 stars if I could.
