Racingline Performance Silicone Boost Hose Kit - 2.5TFSI (2017 on)

The RacingLine 2.5 TFSI Boost Pipe Kit for Audi RS3 8V.2 & 8Y and TTRS 8S is a five-piece kit to replace the factory soft flexible rubber pipes and replace them with beautiful reinforced silicone and aluminium replacement versions. The kit is a direct OEM replacement: simply remove the factory hoses, and replace them with the five uprated pipes.
The Aluminium Boost Pipe has a 70mm outer diameter vs the factory plastic boost pipe's 63mm OD. This maintains intercooler diameter outlet all the way to the throttle body. The Aluminium Boost Pipe also removes the factory wiring loom clearance dent – ensuring smooth laminar flow is maintained.

The Intercooler Outlook Hose incorporates two Convolutions and Stainless steel band – allowing for engine movement without risking hose collapse.
Stepped internal joint transitions give a port-matched laminar airflow path, greatly reducing turbulence versus other non-stepped designs. Of course the RacingLine hoses are pressure tested far beyond the turbo’s capabilities, allowing the system to maintain performance under extreme temperature and high-boost conditions.

By minimising these restrictions, the smoother airflow and optimised hose routing ensures that the turbo meets less resistance and can thus perform more effectively - moving a larger volume of air and minimising turbulence.
Constructed from reinforced high quality silicone, guaranteeing great rigidity to prevent deformation under high boost or heat loads. Fluorosilicone interior surface resists oil and petrol permeation providing extra protection against deterioration.

A great upgrade for any remapped 2.5 TFSI running higher boost than standard.

Compatible with the following Vehicles: 

Audi RS3 8V Facelift (2017+)
Audi RS3 8Y (2022+)
Audi TT RS 8S (2016+)

I was delighted with the quality and color
Size: X-Small, Color: Lilac
This is a super cute, and frankly, fairly high fashion little hoodie. The price was great for what it is. Really nice soft (terry?) inside. Double fabric hood. Really soft. It has an oversized cut which makes it easy to get on and off, but is just the right length to make the sizing look great and intentional - it doesn't look too big. I love the color. It's high quality, and I didn't notice any shrinkage. Even the hood is cut in a chic way. Not your average kids' hoodie.
