Large 4-5/8″ Polished Aluminum Shelby Cobra Style Gas Fuel Cap

This is a 4-5/8 inch polished aluminum fuel cap styled after the classic Shelby Cobra, built as a quick-release, bolt-on upgrade for a classic car's gas filler rather than a factory replacement cap. Construction and finish The cap is machined from aluminum and polished to a bright finish, which gives it both the shine of a show-quality part and the corrosion resistance that bare or painted steel caps lack over time. Its 4-5/8 inch diameter is sized larger than a typical passenger-car filler cap, matching the look of the original Cobra racing fuel caps rather than a stock replacement part. How it works The quick-release design lets the cap come off and go back on without threading, which is both the source of its racing look and a convenience at the pump. Because it is a style upgrade rather than an OEM-fit replacement, check that your filler neck's diameter and thread or latch style matches this cap before ordering. Who it suits This cap suits a restoration, hot rod or custom build where the owner wants the Cobra-style polished look on the fuel filler, on a vehicle whose filler neck accepts a 4-5/8 inch quick-release cap of this type.
