DSG paddle replacement for VW, Audi, SEAT, Skoda models

Why change
S-tronic paddles?

It's all about the attention to detail. And what is more important than the controls of your car that you see and touch every single time you drive?

Our new DSG Paddle Replacements are exquisite CNC-machined billet aluminium blades, beautiful to look at and cool to the touch

The +/- symbols are delicately cut out of the top of each blade.

By extending the size of the blades above and below the steering wheel spokes, it makes pulling that next gear easier in tight turns when your hands are busy with the steering.

AUDI B9 S/RS BILLET OIL FILLER CAP For Audi 2.9TT and 3.0T TSI EA839 engines

Why change
Oil Cap?

The RacingLine Billet Oil Cap for Audi's V6 EA839 engines is beautifully over-engineered in customary RacingLine fashion to give an exquisite feel and exceptional product experience. 

Never again will you worry whether you tightened your oil cap fully - as this billet aluminium cap clicks hard and locks into place.

The precision engineering ensures absolute tightness when fitted, even with the heat soak from a high performance engine.

This cap will ensure that you'll never again have the problem of 'weeping' oil leaks from the standard cap - a known issue with all TSI engines.

A new rubber seal is included with the new oil cap - meaning it's ready to fit!

Why change
Oil Filter Housing?

Tired of staring at your cheap, brittle plastic oil filter housing every time you lift your bonnet? Us too, and that's why we've come up with our beautiful billet Oil Filter Housing to replace it.

The Filter Housing accepts the factory engine oil filter to maintain simplicity and keep that OEM fitment for your future oil changes.

Brake fluid cap for golf R, Audi S3

Why change
brake fluid cap?

The RacingLine Brake Fluid Cap will hold your brake master cylinder at perfect pressure equalisation to ensure that your high-performance braking system is performing exactly as it should. 

Especially with big brake kits on track, rapid pad wear can create negative pressure in the master cylinder

Our replacement Brake Fluid Cap has a better pressure equalisation system than the factory cap, ensuring zero pressure variance

This is an engineered, billet replacement coolant cap to replace the cheap plastic one.

Don’t confuse this RacingLine full replacement cap with other cheap covers - which simply stick on over the plastic cap. We think your car deserves better than that.
