Spark Plugs NGK Iridium IFR6J11 x4 - SUZUKI SWIFT 1.5 05>on: Amazon.co.uk: Car & Motorbike
No issues at all, the main reason that i have installed these plugs are, it can last for almost 70,000KM, there is no need of plugs replacement. In swift, there is no tappet adjustment or any of other type of tunning required except oil change, oil/air filter change.
Hence to avoid the hassle to visit the workshops after every 5,000KM, it is the best option. and i also feel the increase in mileage and smooth in drive with irridium plugs.
