Very good point. To add, if i may, newer vehicles also use secondary (even tertiary) oxygen sensors to control mixture. Newer Land Rovers have known “third” oxygen sensor faults that will cause either a lean or rich mixture. They’re not just worried that the cat is working, but will richen mixture to increase catalyst temps to make the cat work more efficiently.
I tried change the plugged an wires i coudnt brake em loose in less I put a cheater pipe on them an still had to put lot effort bust loose ant never seen that tight should I let a shop do it r do I keep proceed n any suggestions be greatly appreciated thanks ✌️

Platinum plugs have longer life and stronger spark. But they are expensive though…
