It's all about that detail. Replace that cheap plastic washer cap with the stunning MMX billet washer fluid cap finished in anodized gloss black. The perfect addition to an already comprehensive range of under-bonnet dress up parts. Purpose-built to replace the factory plastic cap, it delivers a refined feel and a premium under-bonnet finish that far surpasses the OE part. Each washer fluid cap is precision-sealed to ensure a perfect, leak-free fit. Unlike simple stick-on covers, this is a full replacement designed to integrate seamlessly. Using the latest CNC 5-axis machining, every cap is meticulously shaped, then hand-polished and gloss-anodized for durability and lasting beauty.
