I bought these from ebay and have no use for them. These are STD Bore which means your cylinder walls do not need to be bored out by a machine shop. I provided a link to a auction by the same seller and same pistons. I can not provide a link to the actual auction I purchased them from because it was more then 90 days ago. The price in the auction is the same price I paid. These pistons are still brand new in the box.

Asking $110 shipped.

Here is specs copied and pasted from the auction

These pistons are designed for High Compression All Motor Engines with a Compression ratio of 10.92:1 to 11.57:1

B16A Block and Head 10.19:1

B18A/B Block and Head 11.57:1

B18C1 Block and Head 11.36:1

B18C1 Block and B18c5/B16A Head 11.10:1

B18A/B Block with B18C1 Head 11.57:1

These pistons have Holes in the wrist pin bosses to improve oiling and superior lubrication.

Piston skirts are fully coated for added protection aginst heat.

Oem honda pistons only have 20 percent of the skirt coated.

These pistons are domed to match hondas b16b piston.

40 Percent stronger than OEM honda cast pistons.

These pistons have been tested to support over 350 WHP with the proper tuning and supporting mods.

Wrist pin center to dome height has been matched to within .001"

Dome displacment has been matched to within .005 CC

This results in near identical cylinder compression, yielding more horsepower and better efficiency.
