A billet housing replaces the cheap plastic housing of the Mahle KL 97 Fuel injection Fuel Filter. We have a 10 micron Fuel injection Filter, which handles 60 psi and is twice the Filtering area of the smaller, 40 micron Filter in the KL 97. So the Filter can't split and leave you stranded. Ours filters 4 times better, and goes much longer before clogging. And it's fully rebuildable, so you could clean anytime if needed. You can just run this and no other Filter, if you choose.
