"Decided on this aluminum housing for my 2009 Rav4 after frustrations with the damage-prone Toyota plastic cap.

"I tried other oil filler plugs for my '88 Chevy Camaro with Spectre valve covers, but they were either too loose or just wouldn’t fit. This one, however, has the extra-long shaft necessary for these valve covers and fits perfectly. The quality is solid, and I’m glad I finally went with Spectre’s own product."

"I was honestly impressed by the quality and how sturdy this oil filter housing cap feels, especially compared to the original plastic one.

For the price, it’s a fantastic upgrade I’d absolutely recommend."
