what year is your tahoe?

edit: nevermind

41-803 is the AC part number for the stock replacement CR43TS, but in platinum.

CR43TS is the copper OEM style.

1 is the Rapidfire number.

ACDelco’s RAPIDFIRE Platinum Spark Plugs fit engines that require conventional or platinum plugs, offering quicker throttle response, smoother idle, greater corrosion protection, and greater longevity when compared to conventional spark plugs.
Available for most vehicle makes and models, and several marine applications, the RAPIDFIRE Platinum Spark Plug design features:

Ribless insulator that improves the plug-to-boot seal
Tapered and columned center wire electrode with a platinum pad that reduces the firing diameter and helps improve the firing efficiency by concentrating and directing energy needed to fire the plug with less voltage
One-piece integral suppressor seal that helps reduce radio frequency interference, meters spark plug energy to help provide long electrode life, and seals against compression leakage
Gapped to the engine’s original vehicle manufacturer’s specifications
Thirty-day, money-back guarantee and three-year limited warranty
