APremium Iridium Platinum Spark Plugs for BMW 320i, 328i, X3, X5, 428i — OEM-Grade Ignition

Overview

Upgrade your BMW with A-Premium Iridium Platinum Spark Plugs. Meticulously engineered to align with OEM performance expectations, these plugs aim to deliver crisp ignition and smoother transients across a broad range of BMW gasoline engines. Rather than promising guarantees, they offer the potential for reliable starts, improved combustion feel, and steady throttle response in daily driving and spirited sessions alike.

Crafted for modern engines, they pair a fine iridium tip with a robust platinum core. This combination supports dependable ignition under varied temperatures and loads, while maintaining resistance characteristics tuned for precision control of the ignition event.

Engineered for Ignite and Longevity

Key technical attributes support consistent performance over time. The center electrode tip uses Iridium, paired with a Platinum core. The design includes a resistance of 5000 ohms, a gap of 0.032 inches, a reach of 26.5 mm, insulator height of 50 mm, and a thread diameter of 12 mm. These specifications are chosen to balance spark reliability with durable operation across BMW’s 2.0L gas engines and related models.
