$20, stainless steel brake booster heat shield for s13, I do believe it fits s14 as well (not 100% sure).
Brand new as well.
Significantly reduces booster temperature by insulating booster from hot manifold and turbo, I noticed a huge reduction in brake fade.
Just as good as adding stainless lines.
