## Description

NGK Iridium IX Spark Plug

Review: Worth the extra money - NGK Iridium Nines are great plugs. I run them in multiple motorcycles and cars. I needed a new plug for my Honda lawnmower and decided to splurge. It’s probably overkill for the application but I will never need to replace it!
Review: Easier starting and Improved idle - NGK Iridium plugs are a real improvement over all other spark plugs. The fine wire electrode improves starting and idle quality. Fuel economy is also likely slightly improved.
