Inline PRO Custom M11 to M12 Conversion Transition Tap Kit K / B Series VTEC B16A B18C1 K20A/Z K24A

**SPECIAL ORDER. CONTACT BEFORE PURCHASING**

Inline Pro Custom M11 to M12 Conversion Transition Tap Kit for M12 head studs.

This custom transition tap kit is used to easily convert the existing M11x1.5 threads to the larger M12x1.5 threads for the M12 head stud upgrade.

Super easy to use. Just chase the old threads and convert it to the next larger size for superior holding power.

For the K-series K20 K24A engines, there's no need to drill the block or the cylinder head and uses the stock dowel pins.

For the B-series B16A B18C LS/VTEC engines, there's no need to drill the block but the cylinder head stud holes will need to be slightly opened up to clear the larger M12 studs.

Includes: One custom M11 to M12 transition tap and one extended reach M12x1.5 bottoming tap.

*Please note: "This is not a repair kit and cannot be used on damaged threads!"
