BMW M2 G87 / M3 G80 / M4 G82 Aluminum Oil Cooler Guard

Engineered for BMW M2 G87, M3 G80, and M4 G82 owners, this CNC Aluminum Oil Cooler Guard protects your oil cooler from stone impacts, asphalt debris, and stray hardware during track days and aggressive street driving. Manufactured in Europe and quality-controlled by BYC Performance, this BMW G8x aluminum guard bolts directly to OEM mounting points — no cutting, no drilling, no modification required. The oil cooler is one of the most vulnerable points on the S58-powered G8x family; the factory plastic cover provides only minimal protection, while this CNC aluminum guard delivers track-day-grade defense.

If you're building a serious BMW M3 G80 tuning or BMW M4 G82 modification project that includes track days — or you simply want added insurance for your oil cooler — this aluminum oil cooler cage is built for you. CNC-machined 6061-T6 aluminum is lightweight yet extremely impact-resistant. Black anodized finish offers long-term protection against corrosion and UV fading. Given the high thermal load of the S58B30T0-powered G8x family (M2 G87 — 460 hp, M3 G80 standard — 473 hp, M3/M4 Competition — 503 hp, M4 CSL — 543 hp), oil cooler damage poses serious engine risk. This guard minimizes that risk.

Key Features

• CNC-Machined Aluminum: 6061-T6 aerospace-spec alloy. Light yet durable; proven defense against track-day stone strikes.
• Black Anodized Finish: Long-term protection against corrosion, scratches, and UV fading. Matte black look integrates with the engine bay.
• Track-Day Ready: Protects the oil cooler from stone strikes, asphalt debris, and loose hardware during track sessions. Prevents overheating and oil leaks.
• Airflow Preserved: Optimized hole pattern ensures necessary airflow to the oil cooler; no measurable temperature increase.
• Direct OEM Fit: Plug & play installation on factory mounting points. No cutting, drilling, or adhesives required.
• Universal G8x Compatibility: Fits M2 G87, M3 G80, M4 G82, and M4 G83 — all S58-powered G8x M cars.
• Complete Hardware Kit: Stainless steel bolts and washers included.

Stock Plastic vs. CNC Aluminum Guards — Why Upgrade?

The factory BMW G8x family ships with only a plastic cover in front of the oil cooler. This plastic cover serves an aerodynamic function only; it offers no real protection. During track days or high-speed driving:

• The stock plastic cover cracks or shatters under stone impacts
• Broken plastic can damage oil cooler fins
• A damaged oil cooler leads to oil leaks and engine failure
• S58 oil temperatures reach high levels on track days — under this thermal load, oil cooler damage is a serious risk

CNC aluminum guards deliver:

• 6061-T6 alloy offers impact resistance comparable to steel
• Full protection of the oil cooler from environmental damage
• Optimized hole pattern preserves airflow
• Corrosion-proof anodized finish
• Proven solution for track days and daily use

Installation Notes

Installing the BMW G8x aluminum oil cooler guard is straightforward and requires no drilling or cutting. General steps:

1. Raise the vehicle; remove the front bumper undertray.
2. Remove the factory plastic cover in front of the oil cooler.
3. Align the aluminum guard with the original mounting points.
4. Secure with the supplied stainless steel bolts (torque: 6-8 Nm).
5. Reinstall the front bumper undertray.

Installation time is approximately 20-30 minutes. Professional installation is recommended, though intermediate DIY is feasible.

Care & Maintenance

Wash the aluminum surface periodically with pH-neutral car shampoo. The anodized finish is highly durable; brush away gravel and asphalt particles after track sessions. Resistant to pressure washing.

FAQ

Does this guard fit the F80 / F82 / F87?
No. F-generation cars use different engine-bay geometry; F-generation owners should contact BYC for oil-cooler guard options.

Do M3 G80, M4 G82, and M2 G87 share the same guard?
Yes. All S58-powered G8x M cars (M2 G87, M3 G80, M4 G82, M4 G83) share the same oil cooler location and mounting geometry.

Will it cause the oil cooler to overheat?
No. The optimized hole pattern ensures necessary airflow to the oil cooler. No measurable increase in oil temperature.

Does installation require drilling?
No. It bolts directly to original mounting points. No cutting, drilling, or adhesives required.

Is it suitable for track day use?
Yes. 6061-T6 alloy offers proven defense against track-day stone strikes, asphalt debris, and loose hardware.

Is a carbon fiber version available?
Yes. A Prepreg Carbon Fiber version of the same part is available in our catalog. Carbon is lighter and more visually striking; aluminum is more impact-resistant for track use.

Shipping time?
In-stock items ship within 1-3 business days via partner couriers.

Warranty?
BYC Performance offers a 12-month manufacturer warranty on this product.
