Bostech ISK102 Fuel Injector Seal Review

Installed on 8 injectors and working well after 2 months. Color coding as with factory seals. The only reason you need this kit is for the o-ring on top that seals the bulb tube on the injector. The OEM kit has everything else. Advice. Do not remove the upper retaining ring when installing the upper ball tube o-ring. 3 stars for the dubious installation of the upper black o-ring in the fuel rail hole. They seemed to have too much play compared to the OEM gasket, but so far so good.
