PPI is proud to announce our patent pending injector bore repair kit for BMW engines.
Please make sure to use the drop down menu and select your correct engine or we will ship a N54 kit by default. It is a different repair sleeve for each engine and a N55 kit will not interchange with a N54 kit.
Kits include only the following, correct drill bit, correct tap matched to our sleeve, repair sleeves, drill guide, and an air hose to blow out combustion chamber to ensure no shavings made its way into the cylinder and if so, this will blow them out.
A customer made a nice DIY video which can be found here.

Disclaimer: this kit is to be used to fix a ovaled or worn out injector bore in the head as a chance to keep from having to replace the engine or cylinder head. This kit involves drilling and tapping the injector bore hole. By installing this kit you do so at your own risk. If you are not comfortable doing this we strongly advise having a shop do this. It is typically 1-2 hours labor time.
