Oil Filler Cap Billet Aluminum for VW Golf MK7 GTI and Audi S3 Engine Bay Upgrade

Upgrade your engine bay with precision and style using the Volkswagen Golf MK7 GTI Billet Oil Filler Cap, designed for VW, Audi, and MQB-era enthusiasts. This cap replaces the plastic OEM piece with a CNC-machined billet aluminum part that combines performance, durability, and a premium feel under the hood. The cap is over-engineered to deliver a refined experience, offering a tactile and satisfying “click” as it tightens, so you know the seal is secure every time—even after intense track days or long highway drives.

Crafted from 5-axis CNC machined 6061 aluminum and hard anodised in gloss black, this oil filler cap not only looks the part but also resists heat, corrosion, and wear for a long-lasting finish. An internal spring mechanism provides consistent clamping force and an audible confirmation when fully tightened, giving you confidence that your engine is sealed properly at all times. It’s a complete replacement for the OEM plastic cap, delivering a reliable seal, improved durability, and a premium upgrade to the engine bay’s aesthetics.

Designed for a broad family of MQB vehicles, it fits Golf 7 GTI & 1.8 TSI, Golf 7 R, Audi S3 8V, Audi A3 8V 2.0 & 1.8, Audi TT/TTS 2014+, SEAT Leon Cupra 280, Skoda Octavia vRS 5E, Polo GTI 1.8 (2015+), and Audi S1. The part aligns with the OEM reference 06G103486 and is ISO 9000 certified, reflecting a commitment to quality and consistent manufacturing standards. The cap’s color scheme combines gloss black with subtle red accents for a distinctive yet tasteful upgrade that complements performance builds.
