The S58 Spark Plug (Part #12125A4EF60) is a high-performance M Performance part specifically designed for BMW’s S58 3.0L twin-turbo inline-six engine. These are the factory-spec plugs found in the G80 M3, G82 M4, and F97 X3M.

Key Specifications

Manufacturer: Genuine BMW (often manufactured by NGK/RB).
Heat Range: Engineered specifically for high-boost, high-compression applications.
Electrode Material: Features a high-grade precious metal (iridium/platinum) tip for superior durability and a consistent spark under extreme thermal stress.
Fitment: Primarily used in M-models from 2019 to the present.

Why They Matter

These plugs are critical for maintaining the tight ignition timing required by the S58 engine. Using the official part number ensures:

Pre-gapped Precision: They come factory-set to the exact gap required for stock or mild-stage tunes.
Heat Dissipation: Faster heat transfer away from the combustion chamber prevents pre-ignition (knock).
Reliability: Essential for preventing misfires, which are common in high-performance BMW engines when utilizing aged or incorrect spark plugs.

Note: Enthusiasts running aggressive Stage 2+ or ethanol (E85) tunes often "gap down" these plugs or move to a colder step, but for stock to Stage 1 builds, the 12125A4EF60 remains the gold standard.

Do we ship abroad ?

Yes we do, to almost anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UPS so you can track the package online and could reach America within 48 hours providing its in stock !

However there are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Russia, Nigeria, Macedonia, Syria, Ukraine, Lebanon.

Why is postage on bulky items to some countries expensive compared to some other companies ?

For both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.
