This adhesive is rated for 500F (260C) short term (mins/hours), so if instructions are followed the coin should remain secure under high temperatures. However under certain extended high temp track sessions the adhesive could fail. I have never experienced this personally, but if you do experience a failure contact me and I will get you a replacement.
Note: Mugen oil caps and valve cover only shown for reference. Only includes oil cap coin. Shipping cost may need to be adjusted depending on your location.
INSTALL INSTRUCTIONS:
-Each valve cover oil cap threading is unique, make sure to install oil cap onto valve cover a few times, hand tightening and removing a few times to get it to settle into a position when fully tight. Best to let it go through a few heat cycles with the cap on without the coin to let the seal heat up a few times, and remove and retighten cap by hand before applying coin.
-Install when the engine is completely cold. Thoroughly clean the oil cap surface with isopropyl and dry, remove adhesive backing paper and apply coin at the angle you want. Press and hold firmly. Let the adhesive cure for at least 24hrs before driving.
"Bond strength is dependent upon the amount of adhesive-to-surface
contact developed. Firm application pressure helps develop better
adhesive contact and improves bond strength.
To obtain optimum adhesion, the bonding surfaces must be clean, dry,
and well unified. Some typical surface cleaning solvents are isopropyl
alcohol/water mixture or heptane.*
Ideal tape application temperature range is 70°F to 100°F (21°C to 38°C).
Initial tape application to surfaces at temperatures below 50°F (10°C) is
not recommended because the adhesive becomes too firm to adhere
readily. However, once properly applied, low temperature holding is
generally satisfactory."
