Valve Cover Gasket

Product Details

Keep your BMW’s engine sealed and running at peak operating efficiency with Febi Bilstein’s premium rocker cover gasket. High-performance driving and relentless heat demand reliable engine sealing. A worn or hardening valve cover gasket allows crankcase oil seepage and unwanted air intrusion, which can throw off fuel trim balance and compromise throttle response. Febi Bilstein 188666 is manufactured from heat-resistant polyacrylate (ACM) to withstand aggressive heat cycles and oil exposure without hardening or cracking. Engineered as a direct fit for OE reference 11 12 8 638 124, this gasket gives track enthusiasts and street drivers the precision fit and heat tolerance necessary to maintain proper crankcase sealing under demanding conditions.
