Hitachi 18000 Ring Parts Kit Review

After trying this product on my car, I can confidently say that my engine performance has improved significantly. The parts in the kit are of high quality and are easy to install .The increased horsepower and torque are noticeable immediately. However, the kit is a bit on the expensive side..

As already mentioned, an O-ring, grease and a master key were missing. The rest worked fine, but there's no point in changing everything at once.
