I was going thru my stash of parts and found a spare AutoBoy Japan "High Power Plug Kit" I imported that someone may be interested in...
The AutoBoy High Power Plug kit is a billet adapter that allows the use of an NGK ER9EH racing spark plug. The ER9EH is TINY compared to a standard plug. The volume area around the ceramic and electrode is approx 3 times less, which raises compression.
AutoBoy notes "power and torque you can feel by installing High Power Plug kit..."
I was skeptical, but wanted to try it out- it definitely works; the increased compression and better fuel burn can be felt by installing this little part, -I briefly installed it on my friends STOCK NS (3200 miles on odo) to test it out...

Price is $60 shipped for the high power plug kit in the USA, and i am including a NEW NGK ER9EH spark plug for a spare. ($18)
I cannot use it on my NS since my RS Lips bore and head install.
