コンピューターチューンして10万km以上走行したS660、圧縮測定したみた結果・・・。

It's been about six years since I started driving this S660, and it's clocked over 130,000 km. I had it computer-tuned around 30,000 km. So since the computer tune, it's now clocked over 100,000 km. It's already high mileage, and now it's been tuned, so I was a little concerned. This time, I'm going to do a compression test and, at the same time, replace the spark plugs. #s660 #α #honda #highoctane #computertune #highmileage #compressionmeasurement #compression #sparkplugreplacement
