PMO 46mm Carburetor Kit for Porsche 911 — 2.8–3.0L Performance Set-Up | Air-Cooled 911 (PM-O804-0)

The PMO 46mm Performance Carburetor Kit is the natural next step for 2.8-3.0L Porsche 911 engines with cam, compression, or displacement upgrades. The larger 46mm bore moves more air than the 40mm carbs without sacrificing low-end drivability, and PMO's USA-machined precision means no flat spots, no air leaks, and proper accelerator pump response from idle to redline.

Why PMO Beats Weber and Solex

• Made in USA — billet aluminum machined in California, not Italian casting quality
• 46mm bore — proper sizing for 2.8-3.0L cammed engines
• Precision throttle shafts — sealed bearings prevent Weber-style air leaks
• Proper accelerator pump circuit — no off-idle flat spots
• Available rebuild kits and jets — PMO supports their carbs for the long haul
