Install these spars after reading a Honda forum where they compare the 7V power stripes with resistance vs the 8V power stripes. No resistance and the reality is that my acura integra accelerates much better with the 7 v power stripes increasing the strength and fuel economy in addition the car left the piston I recommend them in honda engines
