With an advancement in automobile technology, higher quality/performance has been required for automobile component parts. NPR products are used in all kind of engines with high quality backed up by proven technology and an abundant lineup.
Nippon Racing Japan products are all made in Japan by the highest standards and with the best production methods available.
Most JDM Nippon Racing Japan products are made in the same factory in which large car manufacturers (including Honda) also buy their OEM parts from.
Nippon Racing Pistons are made using 2618 alloy and a proprietary centrifugal spin casting process. As well as a 6 step heat treatment process to insure a piston as hard as many forged pistons, but with a much lower expansion rate.
Teflon Coated Skirts Reduce Horse Power Robbing Friction and Piston Slap
Less slap = less noise, less cavitation (or liner pitting) and means longer cylinder liner life.
Teflon is the slipperiest material known to man. With a film of oil on the Teflon we now have a very smooth riding piston in the liner.
Wrist pin center to dome height has been matched to within .001"
Dome displacement has been matched to within .005 CC
This results is near identical cylinder compression, yielding more horsepower and better efficiency.Trust the genuine Nippon Racing brand that is really made in Japan.
What is this model of piston for ?
This piston is used in the B16A JDM Civic SIR engine - Standard compression
This piston is an upgrade piston for the B16A2 engine as there will be a small compression increase
The piston is available in standard bore size of 81mm / 0.5mm oversized , we highly recommend accurately measuring the cylinder bore size before ordering
This is a press fit piston to suit the standard Honda conrod only
Picture is of a generic piston set might vary from actual product
