Installation Notes and Tips

Clean the injector bore and mating surfaces before installation. Inspect the injector body for wear, scoring, or contamination that could damage new seals. Lubricate the O-rings with clean engine oil or an approved assembly lubricant during installation to reduce tearing and help the seals seat evenly. Verify the injector and seal profile against the removed parts before reassembly. Standard Ignition SK105 is listed for servicing one injector, so confirm the exact application before ordering.
