EMPI 40mm HPMX Dual Carb + Washburn Big Windows Bundle | VW Type 1 Dual-Port | Save $50 (BDL-HPMX40-BW)

EMPI 40mm HPMX Dual Carb Kit + Washburn Big Windows Bundle — VW Type 1 Dual-Port

If you're stepping up to dual carburetors on your Type 1 Beetle, you already know the catch — once those HPMX trumpets sit where the stock single carb used to live, getting a wrench on a spark plug or syncing the carbs becomes a knuckle-busting job. We solved that in our own shop, then started selling the solution.

This bundle pairs the proven EMPI Deluxe 40mm HPMX Dual Carburetor Kit (#47-8317-0) with our Washburn Big Windows (11" x 7.75" laser-cut steel access panels). Buy them together and save $50 off the combined price.

Vehicle Fitment

• VW Beetle (Type 1): All years, dual-port engine — the EMPI kit fits Type 1 Dual Port.
• Best for: 1600cc dual-port builds stepping up from single-carb to dual, and daily-driver Bugs that want performance without losing serviceability.

Why Choose Washburn's?

We built the Big Windows in our own shop to fix the exact problem dual HPMX carbs create: no room to service plugs or sync carbs. The window dimensions were designed around dual-carb fitments like the HPMX setup, so this is the combination they were made for.

Key Features & Benefits

• Real service access: Big Windows give 11" x 7.75" of clear access to each carb through the rear wheel wells — no more pulling carbs to change plugs or jet.
• Tuning made easy: Syncing dual HPMX carbs becomes a 10-minute job — drop a synchronometer through the window and go.
• Built for each other: The Big Window dimensions were designed around dual-carb fitments like the HPMX setup.
• Quality components: EMPI HPMX hex-bar linkage, dual-port intake manifolds, and stainless button-head hardware on the windows.
