Audi RS3/TT-RS Throttle Body Kit - CTS Turbo

One kit fits them all: the CTS Turbo Throttle Body Inlet Kit now covers every 2018-current Audi RS3 and TT-RS 2.5T running the DAZA and DNWA engines. This improved 8V, 8V.2 and 8Y/8S design delivers a larger, more aerodynamic inlet with a 56% internal volume increase, CAD-optimized and cast from aluminum, with all critical parts CNC machined for perfect fitment.

What is included

• Cast aluminum throttle body elbow with billet aluminum spacer / boost tap
• Large-bore 2.75" throttle inlet pipe with custom silicone couplers and t-bolt clamps
• Boost tap with one 1/8" NPT and one M8x1.0 machined port (fittings not included)
• Two extra 1/8" NPT bungs on the charge pipe for water-meth nozzles
• Hoses and fittings to install on 2019+ DNWA engines

Why it works

• CAD optimized for maximum flow, 56% larger than factory
• Direct replacement between the cold side of the intercooler and the throttle body
• HP gain of up to 20hp on a stock turbo, even more with big turbo upgrades
• Compatible with factory, CTS Turbo and most popular intakes (not compatible with Eventuri intake)
• Compatible with factory and aftermarket intercoolers
• Works with 1-bolt and 2-bolt MAP sensors; DV flange based on factory design
