NGK IX Iridium Spark Plug Box of 4 (BPR7HIX)

NGK is well-known for making reliable ignition components, and their Iridium IX spark plugs are a popular choice for drivers looking to get more out of their engines. These plugs are designed to provide a more consistent and powerful spark, which can lead to improved acceleration and better fuel efficiency. If you're working on a modified engine or just want to upgrade from standard nickel alloy plugs, the Iridium IX series is a solid option.

The fine iridium tip on these plugs is six times harder than platinum, giving it excellent durability. This means you can expect a consistent spark over a longer period, even in high-temperature engine conditions. The tapered cut ground electrode also helps with starting and idling, making your engine run smoother overall. Plus, the trivalent metal plating on the plug body helps prevent corrosion and seizing, which makes them easier to remove during your next service.

This set comes with four spark plugs, enough for most 4-cylinder engines. They fit a wide range of vehicles, including some older Porsche 912 models, various Aprilia scooters, and many ATVs and motorcycles. Always double-check the fitment guide to ensure these are the right plugs for your specific application.
