2025 C8 Stingray of the Year Finalist - Unmodified
2024 C8 of the Year Finalist - Unmodified
I got the one from GM for a non-Z51 with NPP, P/N 87818050. A word of caution, be sure you have the plaque lined up perfectly before you let it touch the area you're placing it on. It looks simple, but it doesn't take much to be off in one direction a little bit and once the adhesive contacts the surface, it's not moving. You can remove it with heat, but the thin aluminum distorts easily ruining the piece. Ask me how I know.
Thank god the area where the plaque is to be placed is embossed as that helps substantially in it's correct installation.
I find it strange that the C8 has always had the embossed area, at least since 2022, yet the plaques that go there have only recently been made available.

The real question Corvette owners should ask is: what preventive measures can we take to avoid an outcome like the L87 failures?
One approach is to increase oil change frequency, especially under high thermal load, to prevent viscosity breakdownand maintain optimal hydrodynamic film strength. Using a higher-viscosity oil (e.g., 0W-40) for track days or even daily use may improve the coefficient of heat transfer and offer better bearing protection under sustained stress—mirroring GM’s revised guidance for L87.
Consider periodic used oil analysis (UOA) through a lab to monitor metal wear, thermal degradation, and additive depletion—providing early insight into engine health.
While there’s no confirmed risk to LT2/LT6, smart oil strategy is cheap insurance.

Some how this post has to do with engine plaques, really.
