Very nice replacement caps for my WRX GT

Great replacement caps. They all install easy. The coolant cap is a bit too tight. Requires a screwdriver to pop it off. Little sanding on the container fixed the issue! The color is a really nice. Pairs with my Subaru nicely!

Engine Bay Caps & Dip stick

Purchased the wrinkle red engine bay caps with the matching dipstick. Quality is top-notch, and the install was very simple and easy to follow. HIGHLY recommend for sprucing up your engine bay from those nasty oem yellow caps.
