The APR Throttle Body Inlet System is a comprehensive upgrade to the factory charge pipe system from the intercooler outlet to the throttle body. We replace all components and provide a new, larger, free flowing system that flows roughly 34% more than stock! This was achieved by increasing the cross sectional area of the system and by reducing the tight radius bend directly in front of the throttle body. Our system does away with two potential boost leak points thanks to our single cast design. We've upgraded the factory rubber intercooler outlet hose to a multi-ply wire-reinforced silicone design with strong t-bolt clamps that resist boost leaks better than their stock counterparts. Our new billet throttle body to manifold adapter provides a convenient boost and vacuum reference point which can be used for a gauge, or anything else in that suits your build. Lastly the system comes complete with new throttle body and intake manifold gaskets, which are common problematic leak point many never know to address. This comprehensive system is much larger than stock thanks to the sweeping design of the cast inlet pipe, and oversized silicone hose. However, despite being dramatically larger than stock, the complete system is a negligible 2.4 lbs over stock! Simply put, the APR system is a complete upgrade from start to finish, flows better than stock and our competition, and is the only throttle body inlet system you'll ever need!

Emissions

This part is legal under the provisions of EPA’s Tampering Policy dated November 23rd, 2020. The company has reasonable basis (test results) to verify that this product allows the vehicle to operate within legal emissions standards and is therefore legal to be sold for on-street use in all states that accept the legal provisions of the Clean Air Act and the EPA Tampering Policy. This product is NOT LEGAL FOR SALE OR USE IN THE STATE OF CALIFORNIA. Testing with the California Air Resources Board, in order to achieve 50-state compliance, is pending with CARB. Once testing is complete with California, and an E.O. number is issued, this product will be updated to 50-state legal status.

Installation Instructions

Please Note: 2019+ model year vehicles require the MS100198-A adapter unless the vehicle already has our full intake system with CI100038-G diverter valve adapter. On some European models, the MAP sensor in the manifold has the bolt hole opposite of the connector, rather than off to the side of the sensor, and as such, is not compatible with this part.

(Go Fast Bits) diverter valve plus install

Installed this GFB diverter valve to eliminate the OEM plastic one all together that are prone to failing. I also spent the little more instead of rebuilding the bottom of the OEM that GFB offers but doesn’t clear all cars. BOV option (any brand) can cause car to have lights & running rich issues if not tuned asap so this was the best option for me to pair with my neuspeed intake. Plug and play harness & works great ! Can tell has less slop from day to day traffic & daily driving.

Good Intake for the price !

This intake sounds amazing at low rpms ! Definitely using some more gas cause it’s hard to keep foot off the throttle lol. Was a tight fit on an 2014 Audi TT Quattro S Line. Engine cover does touch against the intake tubing but fits overall pretty well.

Forge intake pipe

Some slight modifications to the car and the cold air heat shield was needed but otherwise it fit great. Can really hear her breath now!

Very nice!

Love my new side markers - very clean looking and unique in how they flash when turning left or right. The only suggestion I’d make is provide instructions for both installing them and for being very careful with the wire once you disconnect the old light housing Left side went in ok, but I lost the right side into the fender black hole which required me to remove the tire and unscrew most of the lining so I could find the wire!

A worthwhile upgrade

The kit arrived early and complete. All necessary parts were included and installation was straight forward. I installed this upgrade myself sitting on my garage floor.

All the turbo-y, sneeze-y sounds now! Little to no overboost at the high RPM range and boost comes on much more evenly now. Great piece of kit!
