Sav-A-Thread is the easiest way to permanently repair stripped spark plug hole threads. Virtually all engines built today have aluminum cylinder heads. Combining this with the growing number of do-it-yourselfers and the need for quick, easy, on-the-spot repairs makes Sav-A-Thread a must for every store and shop.
- Three insert lengths are available to accommodate all spark plug reaches.
- Positive mechanical locking feature means the insert will never come out!
- The piloted reamer tap means no drilling is necessary and perfect alignment of the tapped hole.
- Includes: Tap p/n 5329-14; Installation Tool p/n 5332-14; (6) Short Inserts p/n R5326-14S-6; (6) Normal Inserts p/n R5326-14N-6; and (6) Long Inserts p/n R5326-14L-6.
Note: Heli-Coil recommends removing the head before installation to insure chips do not enter cylinder.
