I bought it with a genuine part number conforming article, but the size does not fit and it can not be used. I could not return it because it was dirty, after all I purchased genuine parts. Parts fee and time are wasted.
Purchased for replacement of valve stem / oil seal of No. 4 cylinder. Although it was found that genuine can be obtained at the trace (also the price, about 2,000 yen in 8 sets), feeling that the hole of the seal part and the wall strength showed it is much better than the genuine article (truly made in Japan) There was something like a scratch on a part of the seal part of the defect part of the defect, a small amount of oil entered from the part of the seal part burning, and occasionally the smoke was coming out of the exhaust. Also, the plug was constantly wet.
