The 1/2 plenum spacer is fully compatible with the engine cover but is too large to fit the stock strut bar. With the engine cover in place the engine bay looks completely stock with the only difference being the strut bar is not installed. Use the copper if it ever snows in your area.Features:

Warm and stretches to fit without feeling tight, my favorite lightweight knit hat.

Pure 100% Cashmere Beanie for Men - runs very small.
Size: One Size, Color: Black
A soft cashmere which is ribbed. However it is advertised as a Mens hat but size is very small for a man. Would be a better fit for a petite woman. Looks here like it has a turn up ribbing at bottom, but it does not.

Quite short so had to return item
Size: One Size, Color: Classic Grey
I loved the color and texture, but unfortunately, it was quite short so didn’t provide enough coverage.
