Racingline Billet Fuel Cap (Screw-in Style Cap)

Racingline Billet Fuel Cap (Screw-in Style) – VWR190000

The Racingline Billet Fuel Cap is a precision-machined upgrade that replaces the standard plastic factory fuel cap with something far more satisfying to use. CNC-machined from a solid billet of 6061 aerospace-grade aluminium using 5-axis machinery, then hand-polished and anodised in a deep gloss black, it’s a small detail that genuinely improves the everyday experience of owning your car.

This is the screw-in style cap, designed to replace factory fuel caps that thread into the filler neck. If your existing cap screws in rather than clicks in via a bayonet fitting, this is the correct version for your vehicle.

What makes it different

• Machined from solid 6061 aluminium billet, hand-polished and anodised in gloss midnight black
• Integrated pressure relief valve to maintain balanced fuel tank pressure
• New rubber O-ring seal and locating tag to fully match factory cap functionality
• Designed to sit neatly in the factory locator on the filler flap while refuelling
• Closes with a precise, engineered ‘click’ every time

Why upgrade your fuel cap?

The factory plastic cap does its job, but it’s one of the parts of your car you physically touch most often. Swapping it for a CNC-machined billet aluminium item adds a tactile, quality feel every time you fill up, and the integrated pressure relief valve ensures the tank stays properly balanced. It’s a finishing touch that complements other interior and engine bay upgrades nicely.

Fitment

The screw-in style cap suits a wide range of older and smaller Volkswagen Group vehicles, along with several Porsche models. Confirmed applications include:

• VW UP GTI (2016-2019), Golf Mk5 & Mk6, Scirocco, Jetta V & VI GLI, Polo 5 (6C/6R)

Important: Always confirm fitment before purchase. Use the site’s vehicle lookup tool or check the “Vehicle Fitment” tab for the full list. If your factory cap is a screw-in type, this is the correct cap for you. If your factory cap is a click/bayonet type, you’ll need the alternative Racingline bayonet-style cap instead.
