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. WPC treatment reinforces the surface of the bearings, making them highly resistant to wear, which is essential for aging engines like the S14. This durability ensures your engine will stand the test of time, even under strenuous driving conditions. Improved Performance: By reducing friction and wear, WPC-treated rod bearings allow for smoother and more efficient engine operation. This translates into increased power and responsiveness, providing you with a more exhilarating driving experience. Whether you're tearing up the track or enjoying a spirited weekend drive, you'll notice a difference in your vehicle's performance. 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. Included in the kit:

These Motorsport valve springs are from the Sport Evo 3 model but can be used in all E30 M3s (and others). We found that the stock original valve springs can be too weak when used with upgraded cams and this genuine BMW Motorsport part is an upgrade over the original design. Valve springs also get weaker over time so these are the perfect replacement when refreshing the S14 cylinder head. A weak spring can lead to a burnt valve seat or even a bent valve. These are also the stock springs in the M88/S38 and Euro S50B30.

Priced per valve (price includes 1 inner and 1 outer).
