Wagner Tuning S58 Oil Cooler Kit for BMW G80 G81 M3 & G82 M4

By Wagner Tuning
£799.00

The Wagner Tuning Oil Cooler Kit for the G80/G81 M3 and G82/G83 M4 is a high-performance upgrade engineered to improve thermal stability on BMW’s S58 engine.
Designed to replace the restrictive OEM oil cooler, this uprated unit features a larger, more efficient core that delivers enhanced heat dissipation and more consistent oil temperatures during high-load driving.

Ideal for tuned, track-driven or hybrid-turbo G8X builds, the Wagner Oil Cooler Kit increases reliability and reduces the risk of oil temperature spikes — keeping the S58 performing at its best in all conditions.

Key Features

  • High-efficiency aluminium oil cooler core

  • Increased surface area for superior heat rejection

  • Significantly reduced oil temperature rise under load

  • TIG-welded construction for strength and long-term durability

  • Direct-fit upgrade utilising OEM mounting points

  • Supports Stage 1, Stage 2 and hybrid-turbo S58 setups

  • Enhances reliability during track, drift and fast-road use

  • Perfect complement to other G8X cooling upgrades (radiators, charge coolers, manifolds)

Why Choose the Wagner Tuning G8X Oil Cooler Kit

The S58 engine produces substantial heat when driven hard, and the factory oil cooler can quickly become overwhelmed — especially on tuned vehicles.
Wagner’s Oil Cooler Kit delivers a major improvement in cooling efficiency, helping to:

  • Reduce oil temperature spikes

  • Maintain consistent lubrication under sustained boost

  • Protect engine components from thermal stress

  • Ensure stable performance during long track sessions

With its high-efficiency core, precise fitment and motorsport-grade construction, this is one of the most effective cooling upgrades for performance-focused G8X owners.

Installing / Notes

  • Direct bolt-on installation

  • Professional fitting recommended

  • Works with OEM or upgraded radiators and charge coolers

  • Oil system should be properly bled and topped up after installation
