They don't stock these, they don't stock Ruth's. It's like they don't want me getting lifetime plugs from them.

Talking to an FCP rep: "What do you mean a 3 month spark plug change interval isn't normal?"

Maybe the profit margin isn’t as good on these once they buy them at wholesale 🤷‍♂️
Lets keep speculating wildly.

I heard they won't stock them because the plugs cause emissions readiness problems.

Some good info on plugs heat range, gap, projected/non-projected, etc.:

So dropped in the new plugs after I got my car back yesterday from the great timing chain fiasco of 2022, feel fine to me.

I assume it builds boost faster, has increased throttle response, and an idle smoother than a babies bum now?
