Review on 🔧 Spectre Performance PCV Breather with 42845 O-Ring by Jorge Russo

After I put it to the test on my automotive project, I was supremely disappointed by the lacklustre performance of this emission system accessory. While it supposedly helps with engine ventilation, it ultimately did more harm than good. The only upside was the ease of installation, but that's hardly worth the price tag when it doesn't do the job.
