Our new billet fuel pressure regulator fits all E30’s including the M3, all BMW’s with motronic M30 and M20 . These fuel pressure regulators are necessary for cars with increased HP to insure adequate fuel supply. Even on unmodified cars, a slight increase in fuel pressure will usually show a performance increase.
Note: These are a remote mounting type due to clearance issues inside the engine bay. We include a fuel rail adapter which others do not.
