The cowl hood ledge area on the R33 and R34 Skyline is a vulnerable zone where factory access holes can allow water, debris, and road salt to penetrate if left unsealed. This genuine Nissan OEM Cowl Hood Ledge Body Plug is the correct molded rubber cover designed to perfectly seal the 20mm hole in the 64100DB location. With a 30mm overall outer diameter, it creates a secure, weather-tight barrier that restores the factory protection and helps maintain a dry, clean engine bay and cowl structure.
Precision-molded for exact fitment and long-term durability, these plugs are essential during any cowl screen replacement, underhood restoration, or routine maintenance. Over time, missing or deteriorated plugs can lead to hidden rust, water accumulation, and expensive repairs to the hood ledge and surrounding panels. Installing the correct OEM plugs prevents these issues, preserves structural integrity, and keeps the vehicle looking factory-fresh under the hood.
At Terra Firma Automotive, we supply this genuine Nissan OEM Cowl Hood Ledge Body Plug as the authentic, direct-fit solution for R33 and R34 Skyline owners. Sourced directly from Nissan, it guarantees precise dimensions, proper material flexibility, and the quality that aftermarket alternatives cannot match. Whether you are performing a detailed restoration, addressing rust prevention, or simply refreshing the engine bay, these 20mm-hole plugs are a small but critical detail that protects your Skyline from environmental damage and helps maintain its long-term value and originality.
