Our take on the A-Premium 7397 Iridium Platinum Spark Plugs (8 Packs)

The A-Premium 7397 is an iridium and platinum spark plug sold in packs of eight. It is aimed at owners of older GM V8 engines, including Cadillac, Chevrolet, and GMC trucks and SUVs, as a lower-cost alternative to OEM plugs. Iridium center electrodes last longer than copper plugs, but this is a budget brand with little independent test data. Reviewers often mention that the plugs fit as expected and that the engine runs smoothly after installation.
