If you're the proud owner of an S14-equipped, chances are you're passionate about enhancing your vehicle's performance and longevity. One crucial upgrade that can significantly improve your driving experience is Turner Motorsport's WPC Rod Bearing Replacement Kit, designed for enhanced durability and wear protection. Prevent costly mechanical failures and increase engine life with our WPC-Treated Performance Rod Bearing Service Kit!

Enhanced Durability: The WPC Performance Rod Bearing Replacement Kit is designed with superior materials and manufacturing processes.

Preventative Maintenance: Proactively replacing your rod bearings and bolts with the WPC Performance Kit can prevent potential engine failures. As engines age and accumulate miles, wear and tear become inevitable. These components help you address this issue head-on, preventing costly engine damage and repairs down the road. This is especially crucial for BMW E30 M3 owners who value their investment. Long-Term Cost Savings: While the initial investment in a WPC Performance Rod Bearing Replacement Kit may seem substantial, it's a small price to pay for the long-term benefits. Preventing engine failure and costly repairs can save you thousands of dollars over the life of your vehicle, not to mention the peace of mind that comes with knowing your BMW is built for reliability.

Your vehicle is equipped with numerous gauges to allow you to have a better idea of what is going on under the hood. By monitoring these gauges, you can prevent premature engine damage due to low oil pressure or high coolant temperatures. If one isn't functional though, you are in the dark as far as that system goes. One of the most vital is the oil pressure. Replace the sensor to get your gauge working properly again.

Multi-Layer Steel gaskets are comprised of multiple embossed layers of both proprietary high-temperature coated and uncoated stainless steel, requiring less clamp load, creating less bore distortion, and conforms load distribution across the sealing area. The embossed outer layers of our head gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The MLS Gasket (Multi-Layer Steel) features an active combustion seal on multiple layers. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing.
