    So glad these are available as they fit perfectly in the holes left by removing the air injection system. Looks like they came from the factory. Thanks!

    Perfect for Defender 3.5L

    I removed the original carbs and intake from my 3.5L (gas) Defender and needed plugs to block the original air injection ports at the exhaust manifold. I was directed to The Wedge Shop and they were a great help. I needed 8 plugs and these fit perfectly

    These are a much better solution than the previous owner's pinched off air rail. Quality parts that fit correctly.

Thanks again guys.
