Air Pump Injection Plugs – 4 cylinder

$13.50

Description

Clipped and pinched rails. Bolts. Big dollops of silicone. We’ve seen it all when it comes to filling the air injection holes in cylinder heads once the air pump has been removed. A more elegant solution are our plugs! Properly threaded 7/16-20 plugs with tapered threads that require no additional sealant, these plugs are threaded into your air rail injection holes with an allen wrench and clean up the appearance of your cylinder head significantly. These plug kits are for 4-cylinder engines such as the MGB and are $13.50 with free shipping in the Continental United States via USPS Ground Advantage.
