Used 250 amp Littlefuse Mega Fuse (2.7" L, 2.0" bolt hole spacing, 0.64" tall lugs), OEM equipment from various BMW vehicles.  These are great as replacements for your originals, or as something like a fused high output alternator upgrade.

I have several available, as pictured. The auction is for Quantity 1, unless you order multiple. The cosmetic condition varies, but all should be in good working order. They are offered here with a quantity discount so you can keep extras on hand for peace of mind.

Combined shipping savings available.
