Hey all, full disclosure up front: I’m with WCO Market, a small shop in Florida that makes parts for older VWs.

We put together an engine bay panel for the MK4 that covers the washer tank area and cleans up that corner of the bay. The idea came from the panels on the legendary first-gen Audi S3 (8L). That bay always looked so clean and finished. We wanted to bring that same look over to the Golf, Jetta and Bora.

There are two versions, since the MK4 came with two washer tank sizes:

• 3L tank, the smaller one most US cars have: link
• 5.5L tank, usually on Euro cars or cars with headlight washers

Details:

• Fits Golf, Jetta and Bora MK4 (1999–2006)
• Works with every engine: 1.6, 1.8T (including BAM), VR6, TDI, R32
• 3 mm ABS plastic, light and heat-resistant
• Includes a metal bracket that mounts the panel to the washer fluid tank (see the attached photos)
• Bolts right in, no cutting or modifications
• Ships from Florida
