The only tool needed is a spanner or ratchet # 12.
You have only two bolts to unscrew, and of course 4 injectors to remove.

now, you can fit your new injectors. place some rubber grease on seals. Connect them to common rail (just push them in, be carefull with the seal !)

when four injectors are plugged to common rail, fit the all thing back on the cylinder head. make sure injectors are well fitted on the cylinder head. screw the two bolts with your hands

I would personally want to remove the inlet manifold brace for better access, but it's not required. For the sake of a bolt and a nut, I would whip it off though

Lol haha, was hesitant to comment and found it weird no one commented. Also quick question, how many CC are stock injectors and does anyone have some? Good condition or new
