Highlighted Ingredients:
- Resilicore Heat-Shielding Technology: Patented tech for heat protection from cuticle to cortex—more intense than ever.

What Else You Need to Know: Resilicore heat-shielding technology is a breakthrough innovation inspired by resilin—a natural protein that can withstand extreme temperatures. Unlike traditional heat protectants that only coat the cuticle, the size and molecular makeup of Resilicore allows it to penetrate deeper than ever before, into the cortex where heat damage can occur, forming a protective shield that fortifies from within. Created for all hair types and textures. Can be used on extensions.

- Reduction in hair breakage
- Heat protection up to 450℉/232℃ from the cuticle to cortex

In scientific testing after application HeatBounce on damp hair and exposure to 450℉ (232℃) flat iron on dry hair

Do one oil change myself and it’s more than paid for.
Color: Silver, Color: Silver
It is 74 mm. It’s nicely made of cast aluminum. It has a rough cast finish so it shouldn’t be difficult to hold on to. It does fit my Lexus filter and the price is very reasonable. It also fits the oil filter on my 1999 (antique) Harley Davidson Heritage Classic. Which is the primary reason I ordered it. I don’t know this for certain but I suspect it will fit all HD EVO engines. That would be 1984 through 1998 except the Heritage which didn’t change to the 88 Twin Cam until 2000.
