There are a lot of older BMWs out there without the original antenna
still in place. If you aren't respraying your car and patching the hole
there hasn't been a simple solution to keep the hole watertight until
Ensure your antenna cutout has not been modified and is the OEM diameter.
An unmodified cutout will measure approximately .85 inches (2.16 cm) in diameter.
Everyone has tried going to the local hardware store and picking up
an American standard sized plug to fit in a metric hole. The solution
seems like a cheap easy fix until you realize it doesn't fit properly
and it doesn't seal the opening to prevent water getting in. You can
use silicone but that gets messy and never seals perfectly.
We found these simple antenna delete plugs that are the best solution
out there. The antenna delete plugs are simple plug and play
installation. They keep the hole the original OEM size without
modification and best of all, THEY WATERPROOF THE HOLE WITHOUT
This antenna delete plug is the highest quality plug available with
co-molded plastic, the center is made of hard plastic with locking tabs
while the outer layer is soft rubber that seals the hole. Although
the price may be more than a 63 cents from the local hardware store, the
end result is worth it. Treat yourself and get an antenna delete plug.
Remember this plug fits ALL E30, E36, E28 and Z3 models.
