The floor pan and sill areas of the R32 and R33 Skyline are constantly exposed to road spray, moisture, and debris, making proper sealing one of the most important factors in preventing hidden rust and interior damage. This genuine Nissan OEM Floor Pan Sill Side Plug Hole Cover is the correct molded rubber plug designed to seal the 20mm access hole in the 74981WC location. With a 30mm overall outer diameter, it creates a secure, weather-tight barrier that restores factory-level protection and helps keep the interior and structural metal dry and clean.
Precision-molded from durable rubber, these plugs maintain flexibility and sealing performance over time while resisting heat, oil, and environmental degradation. The number of plugs required varies by model and series — earlier R32 models typically need 13, later ones up to 17, while R33 models range from 12 to 17 depending on the specific variant. Replacing missing, cracked, or deteriorated plugs is a simple but highly effective step during any restoration, rust-proofing project, or underbody maintenance, preventing costly corrosion issues that can spread into the cabin or structural areas.
At Terra Firma Automotive, we supply this genuine Nissan OEM Floor Pan Sill Side Plug Hole Cover as the authentic, direct-fit solution for R32 and R33 Skyline owners. Sourced directly from Nissan, it guarantees precise dimensions, correct material, and factory-level quality that aftermarket options cannot match. Whether you are addressing existing rust concerns, completing a full underbody refresh, or simply maintaining originality, these molded rubber covers are essential for protecting your Skyline’s structural integrity and keeping the interior dry and free from contaminants.
