Ultimate BMW B58 PCV & Ignition Refresh Kit

Product Details

Cure the B58 whistling idle and completely reverse the collateral damage. This comprehensive kit repairs the torn PCV valve and replaces the oil-fouled spark plugs, heat-stressed ignition coils, and brittle vent hose in one complete top-end service.

When the integrated PCV diaphragm on your B58 engine tears, it does more than just create a loud whistling noise under the hood. The ruptured valve allows the engine to pull raw crankcase oil vapor directly into the intake manifold and combustion chambers.

By the time you diagnose the PCV failure, your engine has likely been burning oil for hundreds of miles. This thick oil vapor heavily coats the spark plugs in carbon, leading to rough idles, hesitation, and misfires—even after the PCV vacuum leak is fixed. Furthermore, the extreme heat trapped near the firewall on the B58 architecture naturally degrades the ignition coils over time.

This ultimate refresh kit is the definitive "while you're in there" solution. It utilizes the highly sought-after Genuine BMW PCV fix kit (allowing you to repair the valve without replacing the entire expensive valve cover) and pairs it with a fresh set of OEM spark plugs and ignition coils. We also include a brand-new Genuine BMW corrugated CCV breather hose, as the factory plastic line is notoriously brittle and almost always snaps when you attempt to move it out of the way during the PCV repair.
