Product Details

When installing this relay upgrade (longer glow times )we recommend that you also install new glow plugs and ream the carbon out of the glow plug holes. New plugs can better handle the higher heat generated by this relay's glow times.  And don't forget - when replacing pencil glow plugs always ream out the glow plug holes to extend glow plug life.

Please Note: NO Returns on electrical parts that have been installed.
