Review on Engine Injector Removal Puller Kit SF0053 for Audi, Skoda: Must-have Tools for Car Repair Garage and Installers by James Duffield

The Subaru dealer charged me $153 for the labor to install gaskets. I've never done this before. The Humble Mechanic YouTube channel has a video using this particular kit. The video is titled "Replacing Injector Seals on Direct Injection Engines". Everything else in the kit is super extra and you only need a small cone. This is exactly the same diameter as the BRZ direct jet nozzles. The smallest donut doesn't fit on the cone. So start with the knurled ends towards the injector, go to the middle one and put it on. Invert the donut and gently twist to compress the seal. Let it sit for a few seconds. I saved over €100 and would definitely recommend it. I recommend getting a caliper and measuring the diameter of the injector tips if you're buying this for a different engine. I can confirm this works for GT86/FRS/BRZ.
