Question 1

What is Delrin?

Accepted Answer

Delrin is an acetal homopolymer resin, also known as polyoxymethylene (POM). It's known for its high tensile strength, creep resistance, and tolerance to heat and chemicals, making it suitable for demanding automotive applications.

Question 2

Will this fit other Subaru models?

Accepted Answer

This COBB oil cap is specifically designed for the WRX, STI, and Forester XT. While it may physically fit other Subaru engines, confirm compatibility before purchasing.

Question 3

Is this just for looks, or does it improve performance?

Accepted Answer

This oil cap is primarily a cosmetic and durability upgrade. The Delrin material resists heat and chemical breakdown better than the factory plastic cap, but it does not directly improve engine performance.
